Very nice. A no BS answer with no bragging and showing off all your equipment. Good video. :)

This is a fantastic video, so many videos on youtube extol the virtues of these setups but fail to adequately explain how to achieve it. This is so clear and well done, thank you so much

By far the best explanation, without a ton of small talk, and with actually useful information.

About the phase, if you don't have a true ABY box: you can hook an overdrive or a boost before one of the amps. That should reverse the phase. About the ground loop issue, if you don't have a true ABY box: insert a buffer (a non-true bypass pedal) before one of the amps. That will kill the ground loop (without killing you in the process).

How did youtube know I've started thinking about running two amps. Get out of my head. Nice vid, dude.

Congrats! I'd never actually SEEN phasing before!

Great video with simple technical breakdown. I ran ABY & direct interface back in the 80s & you could piggyback off those as well. Look forward to more from you. Thanks

thx for posting. i know little about this but the way you explained made more sense to me than the way it jas explained in the past. i'm definitely going the wet dry route for now on.

Thanks for the very good explanation, very nicely done!!

Great video, so clearly and well explained. Thanks for posting

Awesome video. Great job at keeping it simple and understandable

This is the best video on how to running 2 amps. Thanks

Very informative. Well presented as well. Thanks!!

Simplest and best video I have saw on the subject.

thanks, cool demonstration of the speaker phase!

Nice visual of in and out of phase! Thank you!!

Thank you for this video. It was very informative and helped me figure out the solutions for using two amps.

One of the better video lessons. Thx🤘 cheers

Really nice, simple to understand explanation. Cheers.

Extremely helpful, thanks!

Excellent info! Very appreciated🤘

Thanks for your info and experience. Very clear and helpful

Awesome, well-reasoned, thoughtful video. Thank you for sharing your knowledge on the subject. Looks like I need a Radial Big Shot. Seems to do everything I'll need.

Great video.!. I've been interested in how to run two amps together,along with getting that ping pong effect. Your tutorial was easily understood. I've been playing guitar since a kid.. But running 2 amps is something I've never put much thought into. KZfaq.You gotta love it.

Thank for this video! Very helpful.

Just for anyone who doesn't understand why a sound guy, the guy who's suppose to give you your sound to the audience and we'll, doesn't pan...Panning is pointless for live shows. Even if sound guy put you in stereo like you want him to. One amp through left main, other amp through right main. The audience on left main speaker won't hear the right pan on right main speaker, and vice versa. Which is exactly why sound guys don't do it and a lot of time don't even run in stereo. The few people that are exactly in the middle. Literally right in the middle might hear it but that's a very small percentage and the sound guys goal is making you sounds good to everyone not a very small percentage.

Bro great video in teaching us! Learned all about it, thank you so much!!!

Thanks for the heads up man!

best simple video...watches a few others .did not really understand. Im just starting and this was the basics thanks again

nice, easy explanation and helpful. Thanks

Nice video-I was just hearing about the amp phasing yesterday. Go O's!

thanx for the education session, very helpful. Cheers bro !

Very good explanation mate, cheers

Great vid. Thanks for making it.

Shocking lesson. Thanks

@axescent: You did a fantastic job on this subject

good work buddy. appreciate that

Good points about rehearsal vs. gigging in stereo

Thanks for the info. I'm getting the HOTSHOT

Solid info, in plain English. Bravo. Thanks!

I was looking for a proper way to go stereo as I plan to trigger soft synths through guitar jam on ipad and not to loose the original guitar signal and sound. I even checked out Parker guitars and other piezo/conventional solutions and was quite close to a needless purchase. So thank you very much! Cheers!

Thank you man. I enjoyed it. And am glad that learned more than I expected. Really well presentation. If I apply this, man it would be fantastic.

Perfect !!!. Thank you.

Thanks for this video!

This video saved me of making a big mistake. Thanks for sharing!

super helpful thanks brother

Dual mono with a tiny delay (4-6ms) on one amp is awesome.

Thanks for the info!!

Thank you very informative!

Good knowledge,keep it up

Awesome video, especially the part about being out of phase. I was always wondering what the hell was going on with that! Makes perfect sense now.

If you have problems with ground loop hum I recommend checking out the hum-x. Works wonders for me!

My Blackstar has a ground lift. and I also have a Humx. I play in a lot of older buildings. so I just wanted to prepared. but now I want to hook both amps together. cool video

Sonny you just saved one of my amp speakers 😂 sometimes it pays to not experiment and actually look for an answer

Great video, subscribed!

Very useful, thanks mate :D

Fantastic very informative

Great vid dude thx

You are sooooo good at this. You should make videos!

Awesome vid man, thanks a lot. Hey, what about using the fx loop to enslave amps? Any tips?

Incredible job explaining this. There is one other safe method to interrupt ground loop. Disconnect the ground on one audio cable and it will still drive the input with the tip connector alone. I hope you are still doing well. It's a pretty old video and no new videos for over 5 years.

very clear ,thanks

Charm City represent and good video. I know what to get now !

I was starting to mention the 'other way' and how to do it safely but stopped since you made a statement about it right because it's too easy to do it unsafely... ALSO, ground loops inside the guitar itself is an issue I've fixed for a lot of people over the years as well (and also don't forget that [cliché example, lol] that strats are noisy, low battery in active setups can make a lot of hissing, etc... aaaaanyway, lol, there are a lot of damn variables and examples...lol. (and this comment is to everyone btw. Great video man!!

Great video

my Peavy rage amp has a pre amp out feature! works great,too!

Great explanation. Two questions though. 1) Say I DID want to run stereo out of my stereo effects pedal into two different amps. What would need to go between my pedal and my two amps in order to avoid ground hum? I think you didn't fully answer that since that's rarely able to be done at a venue, but I'd still like to know! 2) To run a wet/dry signal path: The last three pedals in my chain are chorus > delay > reverb. I'm thinking of ending my dry signal chain after the chorus and ending my wet chain after the reverb. However, this seems it would present the same ground loop issue. So I guess the two questions are really just how do I run two different signals into two different amps without ground loop? Because the Radial BigShot only has one input.

Lehle has a stereo ABY called the little dual with a phase and isolated ground. Its awesome

Excellent video. Is it possible that phasing is reduced with different amps or by applying different effects to different amps?

Great video, thanks man. Go O's!

If you use the a/b switch to play over a loop, you can have an orange micro crush or another amp with aux input. You plug a preamp with effect modulator in chain with your looper into the aux input and the A section. You plug B section in your pedalboard into the amp. The looper will play in aux input while you switch directly in the amp for your lead tone. There is many way you can do it you can put your effects before the a/b switch and only a preamp and looper after in section A. And go direct into the amp in section B

Great information, especially about staying safe. Well done. Phil NYC / Jersey Shore Area

Appreciate the video thank you

Great video! I do wonder as some may have access to the speakers…some grill clothes come off and you don’t see much moving. You probably could put something over the speaker that’s thing, to see if it’s sucking in or out. My brain crapped out for a bit figuring it out. But the key was to see what happens when the nite resolves. Here you’re just doing half time type strums. I was just hitting a long E. So I figured when the note resolves, if the speaker pops foward…out of phase. If the speaker pops back when it resolves in phase. I personally just do A/B only one amp at a time. Because running two amps…if you turn one off, volume will drop. However, it can be nice to punch a heavy gain one in and out. That’s how I like to do it! One amp mostly clean and gets the entire board. Dirty amp is dirty, and has no effects. So when switching it’s just a lot tighter sound to get out of say 3 effects pedals stacked…without having to have a Gigrig or scene programmable board. This one helps a lot! As I was having issues in a room figuring it out. I’ll have to get a cloth and stretch it out over the cab to see which way it’s pulling. It’s a bit difficult just looking at the speaker for me sometimes. And some grill clothes are just solid and don’t move at all.

On stage, I used to use a splitter to go to my Marshall Bluesbreaker on one side and a Roland 120 Jazz Chorus on the other. I could toggle between them for clean and distorted passages or both on for balls out.

Thanks for the knawledge

That’s was a kool video man

Good video.

I totally get it now after you explained how phase is basically polarity and by switching positive and negative wires on the lead you can get around not having a phase switch pedal. Nobody explained it like that before.

Nice video. Essentially all you need is an audio transformer to lift the ground hum. It has to be running as a true ground isolated circuit. then the phase switch is also easy to put in too, as this just switches the output from the transformer. That being said the problem comes if you are running different pedals after the Y switch. Then the phase may be reversed by distortion and overdrive pedals. And will give you a true out of phase between the two amps, or in one amp running in parallel input mode. I've thought about running a transformer with every pedal that flips the phase, through a pedal switching board that i'd have to make. Thoughts..

good job thanks.

Thank You!

Thanks mate.

thanks that helped tremendously, now i know the problem. ground loop hum. gotta buy new pedel-cheers.

Thanks man!!!!… very informative!!!!…. I got this thought in my head that I could use a fender bass amp and a fender 2 x 12 at the same time …..I mean …why not. It can’t be that bad but ….I don’t know how to do it so thanks man most likely it’ll be horrible but I’m gonna try it

Thanks for this video. I'm a neophyte when it comes to this stuff. Is there a way to use an expression or volume pedal to control the level of both amps? For example, if I want the cleans of a Fender amp and the distortion of a Marshall, is it easy to use an expression pedal to control the mix level of both amps? I think this would be better than a drastic switch between clean and distortion.... more of a transition. Thanks for any insight.

Hello! great video!. I have a question I want to run my Peavey Classic 30 and Peavey Bandit in stereo with my pedals, so I own five stereo pedals (line 6 mm4, marshall reflector reverb, digitech digidelay, tc electronics nova delay and my digitech jamman stereo looper). In your video you showed that you run the chorus on stereo onto the amps. But in my case I dont have enough cables to run all of my pedals in stereo starting from the first one to the last one. So, does it make any difference if I only run one or two of the last pedals on stereo out to both amps? Thanks a lot! :)

Thanks !

Thanks man

Neutrik makes very small transformer isolators that work fine, Palmer makes one as well, and it has jack in/jack out. With Neutrik you need a female XLR - jack for it to work.

nice hat!

Great vid for sure......But don't you also need an aby with transformer isolate switch that toggles from isolate to direct for extra safety?

Thank you great

Really wonderful informations but I have a question, I sometimes use my fender hot rod deluxe with a fender mustang V2 for stereo setup and my signal goes out from the last pedal in chain ( ditto looper x2) my latest pedals in the chain are :strymon Timeline, strymon flint and the ditto looper x2 with stereo output. With this configuration I have no problems about phases or rumors. Am I ok or do I need an ABY pedal because sometimes it could be happen having some phases or rumors problems? Sorry for my English 😬

Hi there. Thanks for the video. I'm wanting to run a wet dry setup. I have a Mesa Boogie 2x12 a Peavey classic 30 1x12. I want to use my Mesa as my main amp for drives and use the Peavey to put the delays and reverbs in. I also want to be able to run my delays and reverbs in my Mesa too though when just using the one amp or if I'm using the two amps? Not sure if it's possible to have it switched between a wet dry to stereo with the flick of a button? At least I want the wet dry plus the use of the mesa with the delays (in the fx loop of the mesa) I am new to this kind of setup and it's blowing my tiny mind on how to do it. I've got a sore head with it all. I'd love to be to do a wet dry stereo mix. I thought I'd ask you as you seem to be pretty informative to a lot of the other rack videos. Thanks

Hey Man great video. Thanks! I was wondering if you could clear this up for me. I have a mesa head and a diavlo head that I want to run together. I bought the bigshot aby pedal. The only pedals that I use are an OD a noise gate and a ditto. I also have an HX stomp. Currently I have the noise gate and the stomp and the ditto in the mesa fx loop and the od just in front. I want to be able to hook the randall up and have it be exactly the way the mesa is now but be able to use both amps at the same time. How do I hook this up?

Nice Video, thanks! Greetings from London! When we use both A& B and both the sound is coming out of 2 amps, is the guitar signal being split into half and going into the 2 amps? Or is it being replicated? If it is split, don't we then lose signal quality which would then impact overall sound and playing dynamic as you are not getting all that you are putting in from either of the 2 amps?

thank you.

Beware the inexpensive ABY box because splitting your input signal essentially cuts your amps signal so significantly that your tone suffers. Get one with some sort of buffer.

This video is great, thanks. But, in case of 3 combo amps, wich way do you recomend?
