"You keep an eye out and you can get it from the side of the road for free" is the type of thing I like to hear
You can tell, he don’t live in a gated community
Hahahaha yep Thanks again brother.
Correct Gabe, In fact I used to live in a trailer park.
🤣🤣🤣🤣
Loud bang and bright flash....😂....I can relate...
‘Good enough for rock ‘n’ roll’ is my new fucking motto and I want that on a sticker or a T-shirt or a hat… Hell I might get it as a tattoo! You are my hero
Thank you for watching and taking the time to comment Towmotor. I don't remember where I heard that phrase? but its a good one. I surely never forgot it and it helps me not be too critical or crazy on details when I'm building something. Its just got to be good enough for rock and roll, were not playing Mozart in the Phil harmonic. LOL
@@heavymetalATC "close enough for rock n roll" was a Nazareth album
That Hendrix homage at the end was uncanny.. The tone and your vibrato are spot on..
hahahaha I resemble that remark sir. Ill meet you on the next one and dont be late.
Dude, I’m not sure if it’s your delivery or if you actually were slightly drunk, but I was laughing my ass off the whole time. Brilliant!
he's just southern, reminds me of Hank Hill
@@personalPickle Hahah, that's exactly what I was going to say, he's just southern, lmao.
Man , I love your style. Thanks for the help. Your video is exactly the kind of tech support I'm looking for. I'm building a distortion/overdrive using a liberated Telefunken ECC 83 out of an old Grundig stereo console and what leftover parts I've got lying around from working on guitars and junking TVs and DVD players. I have little or no cash and no way of obtaining much in way of parts so the tips like , "you can put in a piece of cardboard" is the shit I'm looking for in DIY video's. Again , thanks and keep on keeping on.
Thank you so much for watching and taking the time to type out such a kind comment Travis. I know how it is trying to do a lot with a little bro. The only reason I can justify or even do the stuff on this channel right now is the youtube checks couple times a year. Ive done gotten pretty far with them now though with a shop to work in etc. soo Maybe ill have a much easier time getting this info out to yall and doing a ton more cool stuff myself.
Thanks again bro truly...
it's folks like you taking the time to write a kind comment like this, that grown this channel despite my going ghost for 6-10 months at a time, that allowed me to buy that little box in the video without having to beg my old lady and do without something infact I was able to get 2 and mail one to the guy that suggested it to me.
Its maybe time I realize what we all got here and start taking this channel more seriously, you have all definitely been more than good enough to me.
Thanks! Been sitting on an amp build for a minute and this helped me understand so much more. Look forward to more from this channel.
I came for the tube preamp how to and ended up learning pedal building principles! I love this video!
This is the 2nd video I've watched by you and this is just the diy content I want to see. Definitely subscribing
Same!
Thank you so much Razman I really appreciate the kind well thought out comment as well as the subscription. I have been unfortunately absent but I should be back to making videos very soon. Thanks again.
This is hands down the most informative channel on here it's just what I was looking for
This is a really cool project. I found it because I decided to build a Valvecaster this evening, but now I'll be building this in the near future, too. The rest of your channel has interesting and useful videos and I really like your presentation style. I'm now subscribed.
Awesome Zeph thank you for watching and taking the time to leave such kind words as well as subscribe. I will be uploading new videos very soon.
i’ve been at building for a few years jsut copying schematics , this is the Best video i’ve seen ! it’s makes things makes sense simply and effectively , thank you 👍👍👍👍
Thank you so much for watching and taking the time to write this kind comment Ash. The one thing that helped me the most was just messing with an ebay breadboard. You can build and existing circuit on it. I like simple fuzzes and just start swapping parts and plugging stuff up everywhere while it running, see what it does different or if something let's the smoke out... Swap caps for bigger for more bass and gain or smaller to tighten it up... Either before or after a gain stage add another transistor stage... Etc etc clippers in different spots. You can make a boost into a fuzz or a fuzz into an overdrive. With just a single bias resistor and cap change. Thanks again for the kind words bro truly and heck yeah dude just start stabbing some stuff in and melt some stuff etc etc. You might make the new "TS 808" or "fuzz face" of the new generation. It won't take long for you to get a good hands on idea of things and start wanting to tweak everything you got. I gotta tell myself it ain't broke don't fix it. 🤣
You are a diagnosed legend @@heavymetalATC thank you again if there was a tip of the hat emoji you would receive it.🤠
also all videos appreciated , and i agree with the idea that the pedal industry seems a bit sluggish and old fashioned and people who do come up with the “far out” ideas seem to get overlooked .Needs more innovation and experimentation which seems to be the whole point of electronics to me.
Excellent, educational, and lots of fun to watch. Thanks for sharing the project Clementine!
Thank you so much for watching and taking the time to leave such a kind comment Ben. You are welcome and I am so glad you found the info in the video to be of value. People don't always get the point of what I am doing on this channel and why but when someone does... it just makes my day. Thanks again Ben.
Glad to hear it! Looking forward to seeing more guitar myths dispelled and shenanigans had 😉
This is golden.
Your content is criminally underviewed my dude.
Thank you so much for watching and taking the time to leave such a nice comment motsiwel. This video has really picked up the views in the last few months. I will also be getting back to making videos soon so that will help for sure. Thanks again
Cheers from spain, mate! Your videos are amazing and I'm really inspired into building my own gear thanks to you. Keep up the great job you're doing!
Hola, Saludos desde el sur de los Estados Unidos. Thanks for watching and taking the time to comment Fran. I appreciate all the kind words of encouragement. If you ever have a question or get stuck on a project feel free to leave a comment.
Heyy, qué pedo tocayo
My dream amp was tube vintage one but I'm from a country which bottlecaps value more than the currency. Now I've got a 10$ diy tubeamp kit from ebay!! Thank you Tube Hero!! SAVIOUR!
Thank you for watching and taking the time to leave such a kind and inspiring comment Xavier. That is so great to hear. I am so happy anytime I can help someone figure out a way to get or make the things that were otherwise not in the cards for them. This should do well for you. It reacts so much like a tube amp a boost pedal or hot pickup will break it up and it will warm up any amp you put it in front of. This would be a great thing for artists to use into a PA when gigging it would totally take away the need for any actual amp on the stage. Thanks again I am so happy to hear that you found this info helpful. That's why I do this. You made my day.
@@heavymetalATC In my perspective, I have semi-hollow guitar for blues, which I don't use it with amp while practicing since the sound is audible without amp with semi-hollow electros. But for recording, plugging it directly to computer wasn't sounding right on my records even though I have a decent audiocard with shielded backplate in my desktop rig. I was just looking for a tube preamp for recording, not for practicing. Hence, 12AX7 are overkill for my case, 6J1's are enough for this. Cheapest one I found was 100$ in music store, but when I had the money, Item was sold out and the cheapest one was 250$ now. Your video solved this issue wholesomely.
System I have:
Creative X-Fi 24-bit 96kHz with custom aluminum faraday cage
Epiphone Dot Studio Carbon Black
Gold jack connectors
OS: Ubuntu Studio low latency kernel
Program: DJack Guitar Rig & Audacity
Brilliant, so glad I watched your video! I've learnt a lot and so inspiring, I'm going to have to order one of those Tube preamps (being a Limey, a valve preamp). Cheers and thanks for your helpful info!
Damn that was an impressive video. I stumbled upon your z-coil video when stuck in a rut of ‘guitar building and modding is expensive’ ++inspired
This is a project that’s now jumped to the top of my play time bucket list.
I love the smell of valves in the morning, brilliant outline explanation!
Excellent guide! Love the humour and diy-to-the-max approach. Thanks for sharing!
Thank you so much for watching and leaving such kind words CTV.
Man, this video is fun! Got me thinking about diy preamp/color boxes for studio recording and mixing. Subscribed!
Dude this is the first video of yours I have watched and you have told me more about tubes that I can understand and I have been trying to do just what I want to do thank you so much
Awesome Bro. I am so glad you found the info to be useful.
Very cool project! I need to grab one of these preamps and tinker with it as well!
Thank you so much for watching and taking the time to comment Kley. I am so glad you liked the video and were inspired to do some experimenting, that is always great to hear. Let me know how it goes and if you have any questions feel free to comment. Thanks again.
Nice work with the Cliff notes explanation. It did help make sense. I think this would be fun. Very inspiring..
Thank you so much for watching and taking the time to write a comment JR. I try to keep it accessible to most anyone. No need in using big words and leaving half the info out to try to seem cool or smart. That aint my style. The point of all this is to inspire and educate. If you try this project let me know how it goes and if you have any questions or get stuck on something feel free to leave a comment. This would make a pretty good first tube project. Its way safer and simpler than pretty much anything I've seen also you could buy a $5 class d amp board from ebay and get a speaker hook it to that and have a full amp. Thanks again.
Cool project! Great presentation, sir. I love YT for this type of content. Love your humor, too. I'm glad your Epi LP Jr. vid. popped up in my feed. Subbed. We all need to share your vids so that you can get the subs that you deserve!
That is Awesome! Well if I would have stayed on a regular upload schedule my channel would be doing much better. I have been working on things behind the scenes this whole time so I should be able to get the videos made alot easier coming back and maybe keep a decent schedule? Hahaha
Great stuff! Pedals and tube circuits are so much fun. I mostly use plugins these days but want to get back into hardware and perhaps some DIY. Love the enthusiasm.
cheers!
Wow. What a lovely guide... Perfectly explains everything.
Thank you so much for watching and taking the time to leave such a kind comment slametal. I am so glad you liked the video and found the info usable and easy to understand.
Hey thanks for this video It actually answered some questions for me but also I really like the way that you explained everything helped me out a lot you definitely got to new subscriber.. 👍🏻👍🏻👍🏻
That was awesome!!! I’m gonna do it man!! That was killer Clementine
Thank you so much Marlon! Let me know how it turns out and if you have any questions feel free to drop a comment.
Wow didn't expect to see a Pete Twofinger invention here. He's a very underrated channel
I learned at TON from Petey.
@@heavymetalATC Me too, I built my dream amp with help from Petey. I would maybe do a couple things differently with hindsight... someday.
hell i love this mc gyver kind of stuff you´re doin ! first the tape video and now a tube amp video ! :D
You REALLY know your stuff, really amazing
You just made me want to go back to school. If I would have had a professor like you I wouldn't have dropped out. You brought me back in bro. Thanks. Gonna go find some old Craig Anderton GP Best.
Thank you so much for all the kind words. MdShack. I never took any kind of education for electronics or music stuff. I just hack at stuff till I make it into other stuff. I never thought I'd really do this kinda stuff much. I would build parts casters and mess with speakers and amos and lots of car audio when I was young but I actually went to trade school for welding and fabrication certification. "Student of the Year" figured I'd get a job at TVA like many in my family but life and health forced me down a different accidental path and I must say it was fate. I LOVE this stuff. It's what I would be doing in my spare time anyway. Sometimes terrible things turn out to be the gateway to a more fulfilling, meaningful existence.
Oh and yes, the internet's... Thank the Lord for the internet's and all the people like Craig that shared knowledge for free.
Light bulb moment circuit overloaded!!!! Wow.. enjoy your videos.
Thank you so much for watching and taking the time to comment AR. I appreciate the kind words.
Man l love your demos. You are hilarious😂. Great show heaveymetalatc
Awesome video man! I just ordered one of those thanks for sharing your knowledge.
Thank you so much for watching and for taking the time to to leave this kind comment Chris. I would love to know what kinds of results you got from it.
Thank you, bI have been building electronic components for decades, and this is by far the easiest and best explanation I have ever seen.

I enjoyed every bit of this video. Thank you!
Thanks man. This is some kick ass guitarist diy shit. Will definitely give making one of these a shot. Thanks for the education.
What a genius. Thanks for the vid, mate. The explanation is absolutely a know how to teach.
Thank you so much for watching and taking the time to write such a kind comment Hobetto. No genius here just poor LOLOL! My buddy Petey TwoFinger showed me this device and my first thought was heck yeah I can make a tube guitar booster outta that. I really appreciate the interest and I'm so glad you found this information useful.
@@heavymetalATC I am kind of sure this device sounds much better than AA random ts9 clone. But my comment was much more focused in the divulgation of the principles of an amp. (And the tone stack calculator, that's cool).
I was personally interested in the anvil preamp. This sounds great, but it costs 400€, all the parts, including tubes. ATM i think I cannot pay that much, lol
'Lets see what it do!'
Instantly subscribed 😂 👌🏻
Sounds great! I'll have to try this. Thanks for the instruction!
Thanks for watching and taking the time to leave kind words Simon.
Dude your hilarious and informative at the same time. Subbed.
Thank you so much for taking the time to watch and leave such kind words Josh. I appreciate the sub and I will be getting back to a regular upload schedule soon.
Just found your channel. I subbed and am watching this video. Super informative and entertaining!!!
Thank you so much for watching and taking the time to write such a kind comment Mike. I appreciate the sub, I will be back to a normal upload schedule very soon.
This is perfect to plug into my "power amp in" on my boss katana. I really want a twin reverb style tone stack
How do u not have a million views my guy i love ur enthusiasm so much
Thank you so much for watching and taking the time to leave such a kind comment Cheesy, I really appreciate the compliment. We'll see if I cant make that happen. I'll be returning to a normal upload schedule soon.
I ordered the parts, and have an old radio im raiding for the extra parts I needed. I’ll post a reply video when I git r dun!! I appreciate the idea and the video!
Super video. Clementine. Awesome playing. Build the same last year. Now working on a ef86 preamp. Greetings from Holland. Paul.
Thank you for watching and taking the time to write such a nice comment Paul. That is awesome! I hadn't really considered this as an option until Petey showed me a link to the unit used. Then the gears started whirling and it happened fast. Let me know how the new preamp build goes and consider making some videos on it. You can use a phone or anything as long as the info is good and you get it to the ones that need to see it... people will be interested. I know I would be. Thanks again.
@@heavymetalATC
I like your channel. Feels like we got the same ideas of building. I feel that I'm still learning, and not able to film it yet. So sorry. But maybe in the nearby future.. I will sign up with your super channel. :).
I think I learned more starting at 17:40 than I have in the past ten years of tinkering with DIY pedals! 🤣🤘🤘🤘
That last part sounded cool!!!
Thank yous so much for watching and taking the time to leave such a kind comment David. That's my poor attempt at Hendrix going crazy sounds... LOL Thanks again bro.
This sounds fantastic. I wanna build one.
Gotta try this.
As usual great video man
Thank you for watching and taking the time to write such a nice comment Tamer. This is a really fun project and quite simple to get up and running. If you try a version of the project let me know what results you get and if you have any questions drop another comment.
thank you.youve opened up my understaning.th very basics and i am greatful
Thank you so much for watching and for leaving such a kind comment TFP. I appreciate the support.
Earned a sub with this one great work. Humorous and informative FTW.
Thank you so much for watching and taking the time to write a comment Huck. I appreciate the sub and I will be back to making videos soon. Thanks again
Good to know I ain't the only one ripping parts out of old TV and Radios at the junk-yard/re-cycling centre, I always have a screw driver and snippers handy, watch yourself though as old Cathode ray tube TV still have surprises for you like implosions and glass. Bring gloves. Great video and commentary , the box sounds amazing for "Hendrix Woodstock" time**!!
Hahaha naw theres a few of us out here looking on the side of the road like... too new, too new... maybe transistors? ahhh, Stop, stawp... STOOOOOOOOP, TUUUUUBES!!!!! hahaha and yeah ive touched the shiny end of a cap and hit the dirt :) only once though. Thanks for watching and taking the time to comment giulio.
Thank you for inspiring me again and again!
Thank you so much for watching and taking the time to comment Herfinnur. I appreciate your kind words. I find that inspiring.
This is awesome!!!! At about @19:00 bro starts channeling the spirit of Domble!!!! Saweett!! :D
There's a lot of good info in here that I wished I'd heard many years ago
I am so happy to hear that Zeph.
Dude! Fantastic video, really helped me make sense of things, and it made me laugh as well! Il let you know how I go with the build, cheers bruv!
FANTASTIC PLAYING! LOVE IT!!!
Thank you so much CarrotDugTooDeep. I do wish I would have remembered to tune the guitar but it was OK we didn't need tuning where we were going. LOL Thanks for the kind words.
Awesome video thanks bro I'm so building one of these 🤘
Thank you for watching and for taking the time to write an awesome comment XIX... Let me know how it went bro.
Great project. Subscribing too ! Supporting the DIY and yours is very interesting. At first I'm searching for this in stereo, trying to emulate the hotness of the old Korg Electribes !
Tell it like it is man ! The best you can do for your tube amp other than using tubes in your pedals is probably JFETS in Fetzer valve configuration. Nice to see someone that knows what he's talking about at last . I use a similar circuit in JFET style in the cavity of a Strat after junking the useless whammy set up and hardtailing it using trim pots. In UK its 'Hendrix at The Isle of White '.
Thank you so much for watching and taking the time to write this awesome and kind comment George. My buddy Petey built an amp a while back with the Fetzer valve preamp in it and man it really was a nice tone. I had a guy say on my comments a while back on a video about a diy alumitone made with copper sheet, you could use a Jfet to boost that and you might not even need a transformer and I was like HUH? Active 1 turn coil??? Yeah Isle of wight was right there at the end wasnt it. I need to get a wah to better replicate that sound... I had a crybaby way way back but I got a multi effects and I was like oh yeah I dont need all these pedals now... left it at a practice space with a couple of other things and you know how such things grow legs... and you realize you still need analog gear for that sound LOL
I smoke 2 joints in the morning!
I smoke 2 joints at night!
Yeah I heard that!
Good stuff man.
Love the experimentation. And if you dont know how to solder but want to try this out, take the time to learn to solder. It's really not that hard for the basics and there is tons ir info on RUclips. Ita a very handy skill to have fo a lot of things.
Very very helpful instructions sir.
Thank you so much for watching and taking the time to write such a kind comment bot5. I'm really glad you found it to be useful info.

Extremely informative with just the right amount of cheeky bastard. Sub'd!
Thank you so much for watching and taking the time to write such an awesome comment. It takes one to know one huh? LOLOLOL Thanks again bro I appreciate it.
@@heavymetalATC it does indeed good sir
new favorite channel
thanks ryan Im so glad you dig the info
Hi Heavy, nicely done.
Hey, thanks again Jeff. 🤝
Great video bud.
I've got a fender champ 25se that's hybrid, as preamp, tube power section and I've been wanting to find a good tube preamp option to mess about with and this is pretty inspiring man
Thats cool man those are neat little amps... Its funny how people will say oh yeah thats Hybrid i dont want no solid state front end... oh, like a $150,000 dumble overdrive special with a Jfet transistor driving it. I made a little hybrid solid state tube amp combo a few years back on the channel and I did a solid state front end going into a tube power section... like dumble and like that amp... most people seem like they think a tube preamp into a solid state amp would be better but... I thinks its just different. I mean hell anything can sound good. Those little solid state rockman headphone amps from the 80s made it on to all kinds of records.. Also Roland jazz chorus... fully solid state, clean as hell amazing sound. It is worth messingf around with one of these preamps though you can get some high signal going into that champ on the clean side and probably get it really talking on the slight breakup tube chug and chime Hendrix SRV kinda deal.
Incredible video
Late to the party but thanks for the great video and info! I've been building pedals for a few years but I had no idea these pre made pre amp boards were out there so cheap. Just ordered one and looking forward to experimenting with it. I really like your channel!
Very helpful info. Much obliged sir. Proper filthy licks at the end too.

Instant subscription from me- high-value advice for those with wallets as perennially bare as mine.
This is really great, and there are so many options to customize this module... I just ordererd one ;-) Really thanks for sharing ! Oh and if you're looking for new post subjects, I'm interested in every analog guitar effect, and even more if they run on vacuum tubes ;-) Thanks again.
Thank you so much for watching and for leaving such a kind comment Philippe. So how did it sound and what configuration did you decide to go with? Id love to know how this worked out for you.
So good. Thank you!
mad hatter guitars makes some really cool solderless guitar wiring harnesses, their parts come in handy for people who don't like soldering. I bet their stuff would work well with a build like this. I used their products to wire up a Dark Glass tone capsule preamp into a pedal enclosure, sounds great, and I didn't need to solder at all. Now I can use this preamp with any bass I like.
Thank you so much for watching and taking the time to type out this useful information Jonathan. I will try to remember to use share this info in future videos.. In fact Im going to put it in my notes and If/when I use the info in a video I will give you a shoutout. Thanks again much appreciated.
Brilliant video.
Thank you for watching and taking the time to write such a kind comment Supperconductor.
Great video!
You rule. Thanks for the education
Loved this video, especially the bit about ice cream. It's frustrating to go on guitar forums and see 90% of people chasing a sound from 50-60 years ago. Not that there's anything wrong with those sounds--like you said, vanilla is good--but there's much more out there than Hendrix and Led Zeppelin. We need to reference the past without being stuck in it.
Pretty good Hendrix impression
Thanks Woo, I find that style of guitar playing to be the most natural for me. Country licks and folk or jazz finger-style guitar playing... not so much it feels like a man with two left hands trying to clap.
Really enjoy your video :D... thanks so much.
Thank you for watching and for taking the time to leave such a kind comment Fausto Ramon, and you are very welcome. I am so glad you found this information to be useful or entertaining. Thanks again.
@@heavymetalATC yea. It is entertainment and useful, So useful that i built my own and i was able to do it because your explanation. I Really appreciate it
Thanks for this one man😊
thank you patrick.
Great vid for us noob want to be pedal modders!
The detail you go into is absolutely incredible. Would it be possible to be able to change the order of the gain stages by building a patch bay in it?
Thank you for watching and taking the time to leave such kind words Dan. Oh yes you could build a patch bay by connecting the in and out on each channel to jacks and then you could build different tone stacks in pedal boxes and just swap them out or use actual pedals in there in front in the middle or after the tubes or you could y them and run parallel.
This sound sweet, cool projet. Now I need to learn and understand better schematic 👌 thanks for the video
I do have a spring reverb box from a marshall, don't know how they work but wonder if this could be added to this pre amp maybe!?
Thank you for watching and taking the time to leave such kind comments Alex.
This is a pretty good start for tube projects. It would be decently simple to just wire it up direct and get it running without understanding schematics.
You could integrate a spring reverb into this but, I don't know if the small tubes have enough power to push the spring reverb directly. They usually want to see a decent amount of power to shake the spring. You could build a separate unit using the reverb tank and place it between the preamp and the amp. I have made one from an old amp reverb tank in a suitcase powered by a computer speaker amp and put it between the preamp and amp.
I recorded the entire build heres a link: ruclips.net/video/1t1sbeOMm3c/видео.html
I gots a Qui Jack in stereo installed on my guitar 😊 I bet I can wire this to work with that.
should turn this into a Tube Wah type dealy so you can make adjustments to the tone with your foot instead of fingers that would be cool, awesome video thanks may pick one of these up myself
That was bad ass. Im building one.
Thank you so much for watching and taking the time to leave such a kind comment David.
6j1 (6ж1, 6ж1п) is soviet tube copy. I had similar mock up with same tube (different AliExpress board) with bass guitar preamp in between the tubes. Didn't had a case, so it was noisy.
For example engl e530 has two tubes as well, is very similar device.
Thank you for watching and taking the time to comment Pakiw. Awesome! I had no idea what a 6j1 was or what it was based on. This is my first time dealing with these little tubes. I'm more used to 12ax7, 12au7, 6gh8a style preamp tubes. Have to say they sound pretty decent I was pleasantly surprised by the results.
Brilliant!
This video is a gateway drug to the rest of your stuff and (bass) guitar effects in general. Everything here is just at a level I can understand but I'm inching towards the deep end to do so. Is there a good book or 'site to flesh out the ideas you mention in this video? I bought that preamp off eBay and I'm going to have fun following the ideas you present here but I'd like to understand what I'm doing. I'm also going to make a bass P90 following one of your other videos. Great content!
Love your videos, and your teaching style.
What if this preamp could be switched between the tubes (or triodes, whatever) being parallel or series?
Thank you so much for watching and for taking the time to write a kind comment Brian, You could wire this in a way to switch from parallel to series it would require a little thinking but it may be most simply done with the use of 4 jacks one for each in and out but have the left out be one of those jacks that have an extra set of contacts that close when you plug the cord in and run a jumper from the output of left to the input of right with it or hell.... Naw...naw that's too complicated... just a simple on off switch to connect or break a wire going from the left out hot to the right in hot so that you can switch it on and use the left in jack and right out jack only now you are in series and just ignore the right in and left out jacks. but you would need to put a set resistor or a potentiometer on that wire the switch is breaking because running one right into the other with no gain reduction sounds like ass as you saw in the video. Ahh I hope that helps or is understandable that gave my brain a good twist.
Could you suggest some good resource material for learning the in and outs of amp circuitry? I have an elementary knowledge of basic circuits from my time spent long ago in electrical apprenticeship program, but would like to learn more for my tinkering habits. Love your content, keep up the good work!
Brother!!
You are funny as you know what!!
