![How To Use Two Guitar Amps Together [Connections, Phase, Polarity & Why Analog Dry-Through Matters]](http://i.ytimg.com/vi/LH9FO1EMIPQ/mqdefault.jpg)
Did michael bay direct this video?
No doubt lol.
And starring Frankie Muniz
For real, I felt like I was watching a transformers movie!!!
This is why his movies are over budget. He's using Marshall amps for explosions.
@@fredache5015 yeah! Malcolm lives forever!!!
He just said "so you dont blow yourself or MORE IMPORTANTLY your amplifier" haha
love that haha
Priorities...
To be fair I didn't cost 2k lol
What are you about 12/13 years old?
I dont mean to be off topic but does anybody know a method to get back into an Instagram account..?
I was dumb forgot the account password. I appreciate any assistance you can give me
Excellent and informative video.
For years I've done the PA side of things and back line has always confused me.
With a PA you follow the same guidance for matching the ohms but you use an amplifier that's at least 25% bigger than the speaker cab and always turn the power amp to full. This allows the cab and amp to deal with peaks in signal without clipping. The complete opposite of guitar amps. I've recently found out that guitar amps are designed to be driven hard and the cones are constructed to take it. This video filled in the last gaps. I knew that guitar gear would blow in certain circumstances, now I know when. Thank you.
im just gonna buy a combo amp damn it
I tried that for years but combos rattle and tend to be hard on tubes, trust me…. I really tried to stick to combos but there’s a reason pros don’t use them much outside the studio
@@alexmurphy5289 I was going to buy a combo but I decided that it's much cheaper to upgrade with a separate cabinet. The guy at the music store was visibly pissed that I wanted to return it
hahahaha🤣🤣🤣
He speaks too fast and show imagens too fast
alright never mind i’ll just play with my amp turned off. no risk of blowing up.
Save on electricity too.
I got to a lot of tutorials and videos. And I must say that this is by far the best explanation video i've seen. Lots of tutorials stay on the surface and usually show some equations without getting in to actual examples. This lets you with no real response to your actual problem. Thanks a lot
This is so helpful, although had to relisten, review it a couple times, thank you very much PMT!!
Great job explaining. The explosions were good to show damage the amp could get from wrong not connecting to the right ohms ..
Excellent information, and a very impressive explosion. Cheers from Canada!
The explosion is the most important part.
Finally someone explaining this in English, literally. Great video. Made it easy.🤘🏼🍻
Very helpful video, thanks for the upload! :)
Thanks. I had this pretty much figured out but I wanted to make sure I wasn't thinking incorrectly. This cleared it up.
Informative and funny, love it ! I miss that you explained what happens with the impedances when you LINK cabinets, one chained to another.
you’re a life saver! both figuratively and literally!
Actually
My mind blew with how simple this is.
Thank you. And beautiful graphics. Cheers.
Extremely helpful video. Thank you so much
Thanks , this was really helpful!
What a show, loved the nuclear animation, good job and thanks!😁
Perfect crash course, solved all questions I had that Everybody else gives a half answer to
I spy a Pompeii sticker on the strat matching their colors. 😉 Also, good video. I feel more informed about selecting and connecting amps and cabs than I had anticipated when I first clicked on. Always used combo amps before so this is exactly what I needed to know. Thank you.
You just liked your explosion effect… It was awesome!
This was very informative! Thank you!
nice and clear explanation. thank you sir!
It’s not gonna make an explosion, it’s just gonna make the a super loud pop! But still you don’t want that, thank god I watched this video! I learned so much, Thank you Sam!
Excellent video. Thanks!
Two thumbs up! very well done
Every guitarist should watch this video!
great explanation
Thanks for the info man!
Very informative, thanks! I missed the scenario where you connect an extension cabinet to a combo amp... any chance to have a video on this?
been looking for this as need to hook up my amps and cabs after having work and move done around the home
thanks this really helped a lot
I love the explosion effect !!
Brilliant educational video with great added fun element. Loved it, great work.
Good explanation. Greetings.
Hi, thank you very very much, thanks to you I finally get it! 👏
Totally. Great video.
5:30 "But always remember the golden rule, never exceed the minimum load stated on the back of an amp."
Exceed the minimum? Did he mean go below the minimum?
So 8 ohm amp + 16 ohm cab = OK
8 ohm amp + 8 ohm cab = OK
8 ohm amp + 4 ohm cab = Destruction
Exceed the minimum, there's definitely something I don't like about that phrase.
SHould ALWAYS exceed minimum load rating ha
Is really how it goes?
@@paginini yeh its Minimum,so ya cant go Below it
Lesser ohms = More power, More explosions
Good to hear a bit of Thomas Mcrocklin at the start of the video!
Excellent thank you
This was so helpful.
I'm going to go drop my "new" Peavey CS-400 on my foot again...
Brilliant video, i wish i understood any of it
Those effects made my day 😂
Thanks for a very clear explanation. However what about the effect on the volume - if any - when you connect an extra speaker to e.g. a combo with an internal speaker. Will the sound be bigger, louder? How would you describe the effect? Basically, what's the effect of connecting an extra speaker to the sound?
Thanks man!! That high Hertz with the nuclear bomb, drove my Jack Russel nuts!
Hi! Nice video Sir. Thank you!
I do have an Ashdown Five Fifteen Bass Amp Combo at 100 watts of power.. It has an extension speaker feature and it says at 8 ohms..So If im going to add an extension cabinet to it, i do need a cabinet at 8 ohms and max power handling not less than the 100w.. Do i get it right?
5:20 'Never exceed the minimum load.' So if minimum load is 8 ohm, DO NOT plug into 16 ohm slot. Exceed means more than. 16 exceeds 8. So no more than 8ohms. But 'minimum' means at least. So 'never exceed the minimum' means use exactly 8 ohms. No more, no less. Either I am correct, or someone needs to change the wording.
I’m confused too because of that
It's okay to run an 8-ohm amp into a 16ohm cab, you just won't get the amp's full power, and it may sound worse, you can't run a 16-ohm amp into an 8-ohm cab, you will nuke your amp. as long as the impedance of your amp is same or lower than the cab, it should not damage anything. Try to keep the same though for the best tone
dont run a cab with a lower impedance than amp it will proably die
he means exceed minimum load going below or going on the negative side of the y axis.
Yeah, 100%. Everybody is patting this video on the back for clearing everything up, but I'm more confused than ever. If my amp head has a load of 4 ohms and my cabinet is 8 ohms, this video told me that is both good and bad.
Hey, So I have Mesa Term-O-Verb Combo, using the 8ohms slot.( 2x16 ohms Celestion Speakers).
I want to add a 4x12 cab, says 8 ohms on cab, do I use the other 8 ohms slot on amp to feed the cab?
thanks man
very helpful
It's all about limiting the electrical current from the amp. High impedance means low current, ok for the amp but won't be very loud. Lower impedance means higher current. That's why your amp can blow, the low impedance speaker isn't controlling the current to a safe level, but allowing too much- and high current means maybe enough power to kill your amp. It's more likely to blow a fuse which every amp should have. Or keep the current controlled with the correct impedance speaker or higher.
Hey Dave. If you can read my comment I just left above maybe you can help me. You seem to know exactly what you’re talking about and yeah my hundred whitehead and JCM 900 4X12, isn’t very loud so I’ve already switched back to my 212 solid state. I need help
Hey Man, had a blast and thanks But, You can't always get what you want. But i do have the MV50 Clean! Thanks Again brother. Bluesman62 Cheers mate.
I didnt know I needed this but I do LOL
Okay. My 5w combo has an extension out. I thought I could get the internal and extension to work together. But plugging into the ext out cuts off the internal speaker. I want to mod that jack. The speaker is 8 ohms. What impedance should the external speaker be if I do this mod?
thoroughly enjoyed those explosions
Plate impedances on a valve amplifier are high, so an output step down transformer is employed, and the transformer secondary is connected to the speakers. The secondary tap for whatever impedance should have a shorting tab to short the secondary when a load is not connected. If the secondary is left open, the amp may be harmed, so for a valve amp, the thought process is the opposite of a transistor amp with a low output impedance emitter-follower or source-follower output device. So to recap.. transistor amp (ohms too low NG) and valve (tube) amp (ohms too high NG).
😮👍👨🏻
One thing to be aware of when combining amps into a single cabinet... A year ago I burned one output on a power amp by using that exact Vox amp in the other channel of a stereo cab. I thought it was really strange and started measuring with a multimeter. Apperently the Harley Benton cab I'm using has connected sleeves even in stereo (I guess they saved a few euros on a smaller switch with less poles).
This combined with the Vox which apperently sends phase shifted voltage through both tip and sleeve made it so that my stereo power amp, which I've been using for years with this cab with no problems since the sleeve is 0 volts in both ends, got voltage from the Vox through the connected sleeves into its 0 and burned the amp.
So from now on I'm always gonna pull out the multimeter to check whatever cab I'm connecting two amps to. If it beeps when you measure the two cables' sleeves, don't do it.
I've been thinking of running my AC30 with a Marshall cab (maybe a 2x12 or maybe a 4x12} but I'm curious if I can do that without blowing it up. Is that possible? I've seen Dean Deleo from STP do it and it's AMAZING sounding but I also don't want to destroy my AC30. LOL!
@@SimpleManGuitars1973 Hard to say, I don´t know anything about the AC30 specifically.
Love all the explosions! LOL!
Hey Sam nice video. I have a question I’m trying to use a amp that has 40 watts with 2 4ohm speakers. I want to use external speaker and still use the built in speakers at same time. Is there a way to do this without giving up to much wattage? Again I want to keep both 4ohm speakers working and like to use a 12in or 10 in speaker as external. What is the best way to connect to those speakers inside to get sound out to external speaker
Hello! I'm going to build a small guitar amp (a kit) that delivers up to 7W. My question is what kind of speaker should I use to get all the "juice" from this kind of amp? Thanks!
If you have a bass amp head that is 1000 watts continuous at 4 ohm and the cab is 1600 watts peak at 8 ohm, will the cabinet blow up if the amp reaches its full volume?
I got question. I just bought marshall origin 50head and i turn it on without a cab to see if it works in case if doesn't to bring it back to store. So, did i damage my amp by turning it on without cab, because it is valve amp?
Thanks for the explanation of solid-state amp impedances.
My Egnater 15w Tweaker head has 2 outputs - 1 labeled "main" and 1 labeled "extension". I'm connecting 2 cabinets, 16 ohms each. Should I a) connect the main output to 1 cab and the extension output to the 2nd cab?, or b) should I connect the main output to the 1st cabinet, and then daisy chain the 1st cabinet and connect it to the 2nd cabinet? Would both set-ups work, and in both scenarios would I set the head to 8 ohms? The manual is confusing - the written instructions imply option (a), but the diagram makes it look like (b) is correct. Any help would be great. Egnater is not responding to me. Thanks!
One question: is my amp head safe even if is connected with right ohms and it's a 50w head connected to a 120w cab with the volume all the way down? while the sound is coming the line out to the interface to the DAW?
Im buying blackstar ID60 and I'm gonna plug it in the bugera 212ts. The cabinet has the power of 160 watts. Can I get the 160 watts out of it using only 4 ohms?
What about when you're connecting multiple cabs together (from only one output on the head)? If I am running a cable from a tube head into and 8 ohm cab, and then a cable from that cab into another 8 ohm cab, which output should I connect it to on the head (4, 8, or 16?)
if your really unlucky and get it wrong with the power rating, the Speaker will/can catch fire, happened to my friend, I was there .
So im looking at an ampeg svt 410 bass cab at 4 ohms what amp heads can I use? Cause I'm having a hard time following this
Can you please repeat how to turn a tube amp into a nuclear weapon? Instrument cable on speaker output it was? Can I destroy the earth when I additionally plug a speaker cable into the instrument jack? And what happens if I plug a second cab into the FX send? Would some kind of paradox appear and end the universe? Thanks.
Run the cab-out, to the input and dial for ALL the gain.
Awesome information, now , I have a single mono output jack marshall cab and two valve heads that I want to merge into one, one head is 20w and the other is 5, i also have an aby switch pedal and a digitech rp1000 , and I want to connect both the aby and the effects processor to both heads and both heads or viceversa, and my real question is how can i get the sound of the two heads if my cabinet has only one mono imput jack?
I think you missed an opportunity to talk about some cabs allowing you to plug 1 16ohm into another 16ohm and then into a cab to utilize a single 8ohm output on the amp
Great Video! So I have an orange th30 just like the one shown in the video. Can I hook up one 16ohm cab and one 8ohm cab??
im very curious with this idea, modeling amp with a speaker cabinet, is it a good idea? will it work? or will it just go boom?
Hey, question for ya! I have just got a new Vox AC30 S1. All I have hooked up is my strat through a SD1 overdrive into the amp, and the amp and guitar pedal plugged into the wall. My amp is hot to the touch after about 35 min of playing. Have I done something to cause the amp to overheat, or is there something I can do to assess what’s causing it to get hot after such a short time?
Hello , thank you for this informative video, according to this, i can plug my ba210 vs ampeg combo to a 280W Peavey 8omh cabinet right with no problem?
Quick question, im trying to learn and came across something i want to make sure of before hooking up 2 cabinets. At 4:28 you show a second 16 ohm cab show up, wouldnt i want both left and right to give 16 ohms each? Would i not keep the switch on 16? Because, again idk yet, but by switching it to 8omhs you now give 4 each cable???? Please get back to me asap as i would like to see the full capability of my amp head before our next gig 😁
I have JCM 900 4100 and 1960AVintage cab. At the back of the amp i set switch to (4)16 ohms impedance and at the back of the cab I plugged the cable to right side (16ohms) and turned it into mono mode. Did it correct or wrong?
Thanks for the help. I just bought the Peavey Invective MH which is switchable between 16 ohms and 8 ohms, the cab I bought is the EVH 5150 2x 12 60 watt, it says 16 ohms. Which switch should I have the Peavey head on 8 or 16??
Thanks 4 video man u scar me with all the blowing up 4 real lol!
I have a Marshall DSL 100 HR amp that has a 1X4 ohm output jack. I am using it with a 4x12 Marshall cabinet with a mono/stereo switch. The right input of this cabinet is rated at 4 ohms in mono. Is it safe to go with the 4 ohm amp to cabinet setup or is it best to stick with the 16 ohm jacks on both?
question: i have two tube amps and two 2x12 cabinets. how many ways can i connect these for optimal audio result?
Warning to those watching at 3 am in the dark, my life flashed before my eyes watching that intro
some fender circuit can handle 4 ohm impedance when you plug and 8 ohm external speaker and the stock speaker is 8 ohm as well.... Example Blues deluxe reissue now on the market... and it's written on the manual.... but still all vintage fender amp can manage...for instance fender tweed deluxe 5e3
QUESTION.
I have two PPC212OB 2x12 orange cabs.
And a orange crush pro 100
Can I run my amp through both those cabs?
If so do I use both plugs on the back on the amp or daisy chain them.
You forgot running 2 mis-matched cabinets like an 8ohm and 16ohm cab. I think the impedance is 5.3 and you connect the 8ohm out to the 16ohm cab and the 4ohm out to the 8ohm cab. They have those series/parallel impedance boxes now where it eliminates the mismatch problems.
PLEASE HELP 😩 !!!
Can I connect my Marshall code 100watt combo amp that only has one cab output at 8ohms to my line6 4x12 cab with two inputs that look like this ...
8ohmsRight---STEREO---8ohmsLeft
🔘 🔘
4ohms mono
(Use this Jack only) So is there anyway possible for me to plug my 100watt code combo amp with only the one 8ohm output to this cabinet that has a left and right input ???
Can I use a “Y splitter” ??? PLEASE HELP !!!
I WILL TRULY APPRECIATE any assistance I can get ... Thanks ... 🙏GOD BLESS🙏 !!!
will/can this work to hook a pa system at the same time
because i have a Marshall 50mg fx i want to hook a pa system to use with a mic (marshell for guitar pa for mic)
what im trying to do is get is an equal vol for both guitar and mic with out having to do them separate or should i use the loudspeaker hook up to plug it in and if so then what should i plug it in to?
I like the explosions haha
I have a Marshall tsl 602 and it has stock 80 watt Marshall wolverines in it. They sound muddy and my amp lacks sparkle, mids. What would be great speakers to bring this amp to life? Any help would be greatly appreciated. Thanks cool video too.
Hello . I've got a question , can I use both speakers outputs of a Rivera Knucklehead 100 ( MK1) into a Marshall Lead 1960A in stereo mode, 8ohm's, as I do with the Marshall 9100 dual block ? Thanks in advance.
Omg I’m still confused.
I have the Blackstar HTV stage 60 and I want to get the 212 cab extension, how would I go about plugging that in? It’s in the plugged into the 1x8 right now is it going to go into the 1x16 with the cab extension?
Hi! I’m new to this, so I appreciate any help regarding one question: I have a stereo guitar amp head (25w/Chanel) + stereo cab (both ENGL). Can I connect 2 cables to the head and then to the 2 inputs of the cab in Stereo!
Hey all got a rockerverb 3 100w and an orange ppc212 open back, 1 v30 speaker and 1 creamback. Do i use 1 speaker cable or 2 to get the most out of the amp? For the one 2x12 cab. Still a lil confused!
I have 4 x 12 fender cabinet with the M-80 but my amp head making noise when I turn it on so what tipe amp head you recommend me for those 4x12” cabinet speaker ?? thank you
Hi! I have a engl fireball 25. It has two inputs. (1x8 and 2x16). Right now using one 2x12 cab 16ohm. Would I be ok to run two 2x12 16ohm?
so i have a peavy 2x12 cab mono input is 8 ohm and stereo is 16ohm, i wanted to gte the marshall dsl1hr but the output says 16 ohm. so i basically wouldnt be able to run this head with this cab?
hi i have a marshall 8100 valvestate and on the back it says "100 watt RMS/4 ohms"
does that mean the 4x12 needs to be a max of 4 ohms or ? i have a marshall cab but ohm meter is showing out put of 28 ohms, so i just need to know what ohm works with this amp head. thank you
hello. I need your advice. I have a Gibson ga5 handwired point-to-point singlended amplifier output 5watts and the speaker says 4ohms
can I use external speaker at 8ohms?
say if i had an AC15 Vox combo tube amp, would i be able to buy a cabinet and extend that amp through that cab’s speaker? i’m pretty sure that the speaker on the ac15 itself wouldn’t be active anymore as i use the cab but what’s important is that i’m able to retain the settings and use the actual amp of the combo to change my sound and stuff
im looking at buying a blackstar ht5 head that has 8 ohms out.i have a old art 825 rules breaker amp,which is stereo 8ohm for each side .i would like to use the head and just the speaker of the art amp.could you hookup and y cable out of the ht 5 watt head and go into to each side of the amp?
One thing I didn't understand. I have one 4x12 speakers 16ohm each one. I must consider so this is a 4 ohm result? Thus, considering the 16 ohm jack on the orange amp, it just may be used in a 1x12 16ohm speaker, is that?
