Fender Tremolux KILLER - 1959 Guild 66-J Masteramp Goes "BEAST MODE"
HTML-код
- Опубликовано: 31 авг 2021
- In this video we'll do an electronics service, repair and modification on a rarely seen amp from 1959 that is remarkably similar to the tweed Fender Tremolux of the day. This amp was badged as "Guild Masteramp" Model 66-J originally, but who really made it? We'll explore the history of the amp and modify it to add some modern features like effects loop and cascaded gain stage that expand the tonal range and usefulness for live and recording. Was this amp made by Multivox amps in New York or Ampeg of New Jersey? Or maybe both?

UPDATE: The replaced CE cap can that was put in this amp by another tech is actually physically vibrating. I'm having to change it to discreet components on terminals after doing this video. Something is amiss in this can's construction. The physical vibration is so violent it's manifesting into audible noise in the circuit. Very odd. I've only ever seen this with power transformers before now that had loose laminations. I also think this amp could benefit from a choke. I can feel a follow up video might be in order on this one.
Will be interested to see the follow up and the vibrating cap, that's a strange one lol... Also, only found the video because I saw your post about it not getting views! I have notifications set to "all" yet still barely ever see your uploads. Methinks the screwtube gods are not happy with your practicing freedom of speech, fuck them... fuck them in their stupid asses...
I watch most of your content. the amp repair does interest me (although far beyond my ability) I have my original 5w red Marshall Mercury amp bought from my aunt's catalogue in 1972/3 still works and sounds great I also have a scala 2 channel amp also this doesn't work but it used to sound really nice till I lent it to a friend hope to get it repaired one day! 🤞🇫🇴👍
An inexpensive Hammond choke for Fender 6V6 amps would be the ticket!
That would be excellent, so we can see what the solution and physical layout looks like. Thank you for all your time and effort.
I was guessing the CE cap was bad. I’ve run into it before, same symptom.
Excellent video, Brad.......great historical review, nicely paced, and the repairs are well presented. Thanks so much !!
Coming from you, sir, that means everything. You are the best.
As a subscriber of both of you fine folks, I've learned a fair bit and let the magic smoke out of the things I void the warranty on a lot less, Thanks guys.
@@n3zyd The pleasure is ours, N3 :)
Hey Uncle Doug! 👋 We're just one big family of guitfiddle players and Amp lovers. You and Brad are really who I watch most of the time.
@@n3zyd i'm a Long happy Subscriber of Uncle Doug and just recently subscribe Brad's channel,both are my favorite and i learn a lot from both Greats😍😍🙌🏻🙌🏻
Ahhh, Brad you are back to chanting those magic words that bring me peace...resistor, capacitor, transformer, rectifier, and my favorite - variac. You and Uncle Doug must be shamans!
These are the videos I enjoy most. I’m dumb when it comes to this stuff but I love watching you do it.
Thanks so much for watching, man. Glad you dig these. The viewership has gone way down of late, so you comments mean a lot.
Hey I didn’t know what a transformer was when I first started watching Brad. Now I have 4 homemade amps and even built a couple for other people! You learn more than you realize after a while without even trying if you find it interesting. Uncle Doug’s a great companion channel if you need some tutorials.
Some pretty wild mods in this. Seems like most old amps need grounding work. Glad your back to these type of videos. Thanks, this was fun.👍
Thanks for watching, man. I appreciate it. Glad you enjoyed.
it's really cool to see the insides of something like this... all of those old style parts and circuitry... great to you hear you playing it at the end... good-looking tele in an offset body...
The guitar is a Zio custom. I call it the "Meteorologist". :D It's become one of my favorite guitars.
Check out Zio Guitars : www.zioguitars.com/
This was a fairly complex repair and re-design. No wonder it took so much time to perform, record, edit, mix and present. My Dad always said, ‘ Don’t let the bastards get you down!’ Peace out brother. Wonderful video.
Great to see him using a proper mic to record the amps now. He's a good player and so much time goes into fixing these things, it's worth accurately hearing the results.
Great video Brad, you seem more at peace and focused. Its good to see you kicking some amp ass. I rarely comment but have been watching for many years. In fact I picked up a nice reel to reel today that I plan on converting and will finally get to use the variac that I bought on your recommendation. Wish me luck.
My favorite kind of comment is hearing that my tinkering has inspired someone else to get into doing this stuff. Depending on the model of reel to reel, it could turn out to be a great amp for you. Good luck!
I could watch you give history lessons all day.
Epic job. Love your methodology and thoughtfulness when considering what to do. Mod sounds great, and even better that it is switchable back to stock. Nicely played sir!
Man, I wish I could go back in time when things were much simpler.
Thanks for the upload. I throughly enjoyed the watch.
Been watching you a few yrs now, you have taught me alot !! I would have to say your one of the best players for an amp tech ever. You can tell the guitar was probably your first love and led to the amp fixing, ? not sure but you rip for sure. love all the content. Thanks for all the work and sharing so much. best tech channel out there.atleast for me..
Excellent mod! Getting the most out f it while retaining the original sound minus the built-in ground issues. Well Done!
I need to figure out a way to block notification for this channel while I'm at work. Not going to get sucked in, no, really, well just a few more minutes...
My only goal in life is to cause people to forget about work and watch me work instead. :D
See this kind if thing is up my alley. Too many times, it's just about guitars, but amps make a big difference in sound too.
I don't know a thing about electronics repair but I watch yours because I like your process. After your comment about lack of views vs amount of work involved I watched in a different way. Big props to you for production and editing sir! I probably was taking for granted all your editing, backing music, creative scene cuts and merges, and sound, especially considering you're a guy working in his basement. (Hey I might not be fast, but I AM slow🙂) Anyway nice job. The amp sounds amazing. And the look (and sound) of that Zio with it is perfect!!
One of your better videos Brad. Absolutely top notch. Thanks!
Nice work, Brad - really impressive you can just splice in a cool mod like that. Sounds great!
Glad to see you back in action.
Really informative! Thx man. Greatings from Germany, the country without vintage amps.
Not just a comment for comment sake, We always enjoy your amp videos. And the playing at the end never disappoints. Rock on brother.
I am REALLY glad to see you back in your' game! I continue to pray for you on your' other issues.
I'm a fixer. I refuse to be broken.
These are strange times I thought this video like all your amp mod or repair videos was top notch as always I have watched all your amp mod videos multiple times your one of the best at it
inspiring to see you doing these mods brad, goes to prove that these amps had
flaws in design that are not beyond redemption, the sounds are bang up to date
and dragged kicking and screaming back into modern life with your TLC,
fantastic work as usual ,keep it coming ,sitting here watching the river flow!
I like taking amps that are forgotten or overlooked and making them shine. I mean, sure, Fenders are great and all, but something like this is an underdog. I like underdogs.
Hey Brad, I had zero interest in Amp repairs & mods before I came across your channel a year or so ago, I normally plug em in & pray they sound great..........But your Videos keep me super interested & given me "new ears"....Thanks Man
This video was a marvel to watch. Well done!
excellent video Brad .. You really Made this amp Shine !!
Great video - I have learned so much about valve amplifier tech watching you & Uncle Doug.
Great video brad! I really enjoyed this one its been a min stay safe and keep rocking.
One of your best mod videos ever!! Great to see you back and focused!!!
I've produced several amp vids recently. None of them are getting seen.
Well looks like you got a lot more views over the weekend. Glad to see it.
I always love your vids and your live chats.
Please dont stop
Hey Brad. Been watching your videos for awhile and finally subscribed! I’ve been watching RUclips for years and you’re the first channel I’ve subscribed to. No reason it’s just how I roll! Saw your post about your latest video and had to subscribe. Please keep the amp repair videos. I don’t know anything about amp repair but find the videos entertaining and I think I learn some things! Just wanted to show some support.
Great update to a sweet old amp Brad! Nice job.
wow this is great these amps are rarely talked about!
Totally enthralled by the whole process - Great vid.
Glad you enjoyed it. Thanks for watching!
Thank you for the great video Brad
I have a cutting board size piece of granite that I got from my parents leftover new kitchen counter. Works like a charm as a little soldering station. You can’t burn it and it never heats up.
This is so amazingly versatile. Love it.
Damn!!! That amp is sweeet!!! Great work Brad
Sweet Amp nice clean up job looks excellent sounds amazing. Beast mode indeed
Man, that thing sounds awesome. Such a such a killer sounding OD tone
Another fantastic video Brad 👍
Keep them coming Brother 💯
That's a real nice sound. Thanks for the video.
Thanks! I wish I had not forgotten to turn up the room overhead mic during the demo. I usually like to mix a little of the Beta 87A condenser in to get ambiance of the room. Makes it sound less "boxy" to me. Closer to the actual sound of the amp. But it turned out ok.
Another great video Brad….I watch your channel for a number of reasons….I’m a guitar player/collector/nut……I also love how you are sooooo good at what you do….if you do see this I’ve always been curious where you acquired your unbelievable VAST knowledge of amps/electronics …and third you have a great personality….and seriously lately love your versions of Everly Brothers songs…be nice if you could do another couple completely….all the best from CANADA 🇨🇦
Same as Dan Macintosh's comment, i typed in "new guitologist posts" and this and a few more popped up!
Ill keep watchi g your excellent content as long as i can find them!
Sorry youtoilet is goving you such problems!!
Keep on posting for as long as you can, you have many appreciative fans that would seriously miss you and your insru tive videos, your rants and observations too!
Awesome video dude!!!!!
I didnt have time for long video during the week but the weekend ! Great amp never seen a Guild amp sounds real nice !
Brad great ideas /information - loved the singing also :-)
Excellent video!!! Sweet amp!!!
this is a great video and a cool amp. i think you're in your prime with these oddball amps. would definitely want a sequel in how you handle the vibrating cap
Heck yes! Nice work.
Excellent video
The "Beast" mode sounded awesome. Keep up the good amp work :-)
I know the feeling when trying to pry a wrapped lead out of a tube socket or something, and it breaks. Been there, done that at least a couple of times.
Beast mode for the win. Nice job!
Great video and killer sounds at the end
Thanks man. Good to see you as always.
What a cool history lesson, good stuff
Beat channel is asome. There is hint of sound old Jimmy H... Sound. It does really smooth feedback too. Really Good work.
Great vid bro
Great job . Full view .
What the hell you have a really nice voice!! Good pitch and tone
I wish you would have thrown something into the effects loop. I really wanted to see you dial in a great reverb/delay tone on a vintage amp. Great video Brad, and great playing too!
Brad, good video, 👍, when you have a 4 section filter can, you have a common ground for the power amp, and the f/e. That doesn't work in my experience. You may want to try to separate the
f/e ground from the filter cap. I've had the same issue many times with the 4 section can. I just use 3 with the common ground, and use a separate cap for the f/e supply. Cheers
Thanks for the comment. I have had so many experiences with different amps and I think you might be right. Some amps don't seem to mind, but now that you mention it, maybe that's worth experimenting with. I need to get back in this one anyway to replace that vibrating can cap. I think the fault is probably physical in the construction in this case, but I'll mess with the grounding scheme more if it persists.
Yeah man, nice work \m/
Love the Weller soldering guns. I have 2 of them that I use. I have a power regulator that I built to plug the guns into so I can set the temp. I like your can idea. I'm gonna borrow that if you don't mind :) The amp sounds great! I see the addendum about the cap can. Looks like a Part II is in order. Cheers, Brad!
I enjoyed the tech content mixed with the history!
lovely amp !
Second time watching this. I *loooooove* the history at the start, would very much welcome a history dive any time you actually can for some of the really awesome pieces of gear you get :D
Maybe I'm just also a history nerd, who knows
I love history too. And detective work.
@@TheGuitologist I've always said that the love of detective work and mysteries combined with electronics is one of the things that drove at least me to repair work, especially on older or 'vintage' pieces. You often get to indulge all three with vintage electronics repair, and it's the history aspect that makes it extra special at the same time.
I've got a few bookcases worth of books on electronics and engineering etc going back to the 1860s. Often find hand written notes in them, newspaper clippings etc. Combining history and electronics makes me very happy haha :D
Love that your passion for it all shows and shows in the quality of work you do. There are others in the same field on RUclips, but each is unique and so no one else does these videos as you do :)
Great amp great video
loved your vocals
Nice of you to say. Thanks.
I had a friend 20 years or so ago that had the Marvel 25. Until this video, id never seen another one. Thanks for the flash back ;-)
Wow yeah that was an awful lot of filtering going on there.
I agree, i wish more amp companies would mark the tube sockets and what they do clearer.
I can't believe he had me engaged for over an hour. Good job!
Long videos are certainly a risk. Not many viewers have an hour or more to watch a RUclips video. Glad you enjoyed it!
I love you man!! Brad, I don't know if you get enough compliments or not. Here's one. You are the guitologist no doubt and much much more brotha! Thanks for your videos!! You ROCK 🤟😆
🎼 🎙🎤🎸🎻🪕🎺🎷🥁 🎹 🎛🎚📟 📻🔌🖥 ⌨🖱
Mr jack of all trades! 😊 I usually don't complement enough people I watch on RUclips. I've watched you since way back in 2013 I believe. Been a long time! I'm glad I subscribed to the guitologist. Have a good one!
thanks for the words of encouragement. Sometimes you spend days or even weeks producing an hour long video like this and it just flops. No one see it because the algorithm just buries anything associated with me anymore. It's nice to hear a few people still get something out of the videos.
@@TheGuitologist brad, as long as your videos are on RUclips, I will continue to get more out of it than I ever would without you.
@@TheGuitologist Brad, I keep my notifications on.
🤟😆👍
Beautiful amp.
Yur gonna have to hold on to that amp for another 20 years to "monitor" for that noise. :)
Hahaha. I'll speak to the owner about that. Maybe he'll agree. :D
Is excellent video brother
I loved the unexpected Thrash music about 38 minutes in! Great video as always Brad!
That was pretty badass! Don't know who it was but it sounded 'homegrown'. Like 8-track reel to reel homegrown. \m/(>
Watching I learn, but still get lost lol. Each video I learn a bit more thanks for the detailed information.
My vids are not meant so much as tutorials but as entertainment and inspiration. I will sometimes get geeky on the technical stuff, but if you want the real technical breakdowns, be sure to subscribe to Uncle Doug's channel.
@@TheGuitologist thanks for info and I will look into his channel. However even though your videos are for entertainment I still learn so thanks again.
@@TheGuitologist love uncle doug too
Nice job :)
Thanks Robert. Good to see you.
I love these videos
great Brad! i really like this mod , it's kind like having a super lite marshall now, but the option for a clean tone too , i guess...
i would like to add a passive fx loop to my 5e3 conversion , but i'm afraid the signal out of the normal channel pot as send would blow my pedals 😁😁, great job anyway , enjoyed the video a lot 🤟
Nah. You should never have any issues with the signal after one gain stage. The only way your pedals could be affected at all is if the first coupling cap in the amp shorted, but that's not likely.
@@TheGuitologist cool i might try then , maybe i add a separate box , it's kind a odd amp , pre amp is apart and connected to the power amp with a cable, so i can just disconnect it and run the signal through the send return box , or just add a solis state fx loop and feed it with the last nod , think it can work ! thanks👍🏻
@@antonix_81 That’s normally all an FX loop is. Some amps even label them “pre-amp out”/“power-amp in” instead of “send”/“return”.
@@OtherTheDave yeh kind like the matchless dc30 one uses
Art of War is a nice touch sir 👌
I would Love for You to rebuild my Ampeg Reverberocket 2 amp to what you did on this amp. SWEET SOUNDING old amp. GREAT Video Brad
So enjoyed watching and more importantly learning... people the world over are losing their shit over covid.... everyone is a bit distracted. Awesome vid again super informative... thanks man. Geoff. Australia. 👍. Can't be doing to bad..the other amp god.. Uncle Doug was watching. We make content no matter what subject. For ourselves. Keep ya chin up mate. Cheers.
job well done.
Great work! Gotta be careful using a soldering gun..pretty easy to overheat and maybe damage components. Also the tips get soft once they heat up and are easy to bend if you try and pry with it or push too hard against the joint.....been there done that .
Thanks for an interesting video! Cheers!
This is true. I have to remind myself not to use it to pry like I sometimes use the iron.
Dang that sounds good.
Ok I finished it as per my comment on your post, great video, great chat, great song, do you have a link for it, and the amp sounds great and your playing, too!
The locusts in the background make me yearn for warm dry weather again. In South Carolina, it’s hot but better than this wet cold shit we’ve been having lately :)
Brad, good call on the filament wires.. however, i always put effects loops in between the pre-amp stage and power amp.. reason being as the type of effects you run in an effects loop are modulation, delay, verbs, etc.. things you want post tone stack.. to effect the whole sound and not change it before or mid stream.. then you can use the return as a power amp in, to bypass the entire pre-amp too.. or the send to take the pre-amp signal to a outboard power amp.. very useful to send to an amp/cab sim or straight to a board or for recording/mixing.. the way you have it, you might as well just run all pedals/effects before the input like you would distortion, compressors, etc.. as always, great content and thanks for creating for us.. btw, how's the school board meeting case going, hope the dropped the charges.. sorry if i missed an update.. we care about you man.. we stand for the same principles
The FX loop that Brad put in is going to be useless. It's the dumbest thing I've seen on this channel. It just doesn't make any sense.
I appreciate the comment. Good to see you again, by the way. There are no additional stages of preamp after the loop besides the PI. I accept the criticism, but also, the benefit of placing the loop where I did is that you get an additional "mode" to the amp by allowing the Return to double as an instrument input and still have tone controls. So you can still use the loop as you suggest to affect more of the amps' overall post "gain" tone while maintaining the third "mode". That was my thinking anyway. Not saying I'm right though.
@@TheGuitologist I'm beginning to see sense. And in the end, what matters is how the owner is intending to use the FX loop. If this solution serves the needs of the owner then it can't be wrong.
@@TheGuitologist I mean, it just takes a chassis-mounted 4pdt switch and you can move the loop between the two locations, right? Then both you and the OP can be right and wrong at the same time.
That’s gotta make this some sort of advanced quantum mechanical amp, right? 😂
I was just thinking part of rattling or noise owner could have been hearing was a loose bell on that speaker since it fell off on the way in transit. Along with other stuff you found. Will wait to see the follow up but it does sound good.
Off topic, but yesterday I found a "Fender Harvard"! I had to share. I didn't even know they existed!
Uncle doug on youtube just worked on one it was a fender tweed Harvard
Was it on RUclips? lol
@@graxjpg No
I was about to say...Uncle Doug's latest is a Harvard.
@@TheGuitologist yep and I heard it and it sounded really good and also the amp you worked on today sounded good too
I was trying to show my love for your channel. So I went with your last suggestion on your list, when the cops came I told them about your RUclips- one of the officers appreciated my suggestion and found my antics funny the other two did not. I ended up taking a ride In the back of a cop car and spending 72 hours in the hospital for an emergency evaluation- 🙃 I told them I was crazy but not a threat to myself or anyone else- most of the time. They just couldn't believe I ran down the street yelling Long live the Guitologist naked sober in 30 degree weather. I said to them yes I was sober it may have been why I thought doing that was a good idea.
Moral of the story kiddos - don't get caught running down the street naked, go home and put your clothing back on before the cops come. You can still tell them about the channel. But you won't have to get Ep"ed by the cops.
Sometimes you need to think inside the can.
Touche!
Brad you are a badass buddy, I live too close to you not to stop by sometime. I built a pickup winder a while back and I’ve been dicking around with different alnicos it’d be cool if you installed one and gave me some feedback. I guess I’m partial to your channel because I’m a huge tinkerer and builder of things. Also a huge fan of your political views, I just can’t wrap my head around how the world has gotten to this point as well. Keep doing what you’re doing brother it absolutely doesn’t go unnoticed!!
That original wiring looked like a train wreck! Talk about bandaids. I'm an electrician,but electronics is a completely different "beast" enjoyed the vid, I'll keep watching👍
Beast mode is gnarly! That’s a metric shit ton of gain for only two stages!!
Thanks
Thank you Alan! I really appreciate it.
It looks like SANO grill cloth, I have a SANO 30W. SANO did some work with AMPEG. SANO amps are well made.
