How To Use Two Guitar Amps Together [Connections, Phase, Polarity & Why Analog Dry-Through Matters]

[@michaelwebb4082]

This is kind of a full circle video for me. The only reason I found you guys was because I searched KZbin for a video on how to use two amps about 5 years ago. I had absolutely no idea about effects pedals, other than something like a zoom 505 or a digitech rp100. I had a pod xt live at the time and when I found you guys, it completely changed my life. Here it is 5 years later and I’m such a gear nerd, I have over 40 pedals, 9 guitars, 7 amplifiers, and I am so much more educated on everything guitar and gear related. You guys are and have always been the best guitar and gear related channel out there, bar none. Love you guys, and keep on doing what you’re doing!

[@tleewandel]

I have to use a phase select block in my Quad Cortex when I use 2 amps W/D, and when I use my Chroma Console (with stereo outs, go figure) I have to use a humdinger in order to switch the phase as well.

[@Real-time22]

Same here😂😂 and to make things worse, UA makes some killer looking and sounding pedals at 400 ma each …and then there are the Gigrigs.🤘🏼👀💵💰

[@robertwillett4122]

Once you figure out the polarity and the ground lift to have no hum. There's nothing better than ( I call it ping ponging) a good chorus, delay, or an ambient type of effects. But it can be difficult. You must educate yourself. It's incredible. You guys did a great job.

[@buffalofeathers]

As someone who IS into this, it WAS gold! Thanks, gentlemen!

[@jbels41]

This was so over my head, but there is nothing better than two people being passionate, educational and funny!

[@simoneh4732]

I've always avoided the ground/earth loop by having both amps plugged into the same power strip/bar so that they are on the same ground potential. My understanding is that the hum actually comes from two amps being connected to different grounds which usually have slightly different ground potentials, and then when the loop is made, current will flow from one ground to the other through the amps, and that gets amplified as hum. Having them on the same ground greatly reduces this so that I haven't had hum problems by just using a pedal to split the signal. I happen to be lucky that what comes out of both amps is in polarity too.

[@martynrandall7652]

Your right about everything plugged into 1 socket. They don't mention it maybe because they won't sell as many humdingers? Lol

[@billtravis523]

Nice addition of a simple way to bypass the dangerous and humming ground problem! I've been eyeing a triple-socket, heavy extension cord from the workshop for getting amp and pedals powered quickly with only one cord to plug in when I want to practice. (I always unplug from the wall when I'm not playing.) Your input adds a reason beyond simple, one plug convenience. Will be mindful to not overload the wall outlet with the items plugged into the triple end.

"Why?" "Because it's Awesome!" Roll credits...

[@lynette9021]

Really, today's question is, "How can you NOT use two amps?".

[@1970sman]

You are joking?

[@evanmiller2579]

Learned everything I know about two amps from this show. Biggest mistake I made was flipping polarity on the gig rig to get the amps in sync and then going into a stereo reverb pedal (Boss RV500). Since the two signals going into the pedal were out of phase, the reverb volume was almost non existent. I thought something was wrong with the pedal. Once I figured it out, my best results came from doing everything on the board including going into stereo pedals and then putting a humdinger on one of the stereo outputs only. That way I could kill hum and flip polarity if necessary. Have a great weekend.

[@gyugug]

Excellent episode once again chaps. For anyone hasn't tried this, it's a game changer. Another thing - the more diverse sounding amps you use, the wider the sonic spectrum - for example I use a Roland JC120 with a Kustom 100. Another thing - as Mick rightly mentioned - it doesn't have to be TPS wet/dry e.g. I use separate fuzzes on each signal path - wet/dry fuzz is a new dawn! Cheers :)

[@tyronemckenna2541]

And another thing! lol

[@jamiebarr9810]

I am still very much an Absolute Beginner on this, after watching the really in-depth vids, I really needed this! Next trick - find a suitable amp for home playing to match with a Blues Jr and add a Humdinger to my board!!! Much love, guys.

[@ajb625]

I only play in the house, and have always used two amps. When people ask "why"?, I answer "Why not? I've got 'em!". And yes...such a big sound with minimal volume! Someone went through all that trouble to make the amps...we should use them!

[@jamiebarr9810]

What two amps do you use?

[@joeschlicht]

Same here. I actually have three amps, but one isn't turning on right now. Hope it's just a fuse. But to your point, two amps sound huge! I'm currently playing a tweed deluxe clone and a handwired AC15 split, and I'm only just over 2 on the deluxe volume and less than halfway up on the AC15 and that's plenty lound for a rehearsal with drums, bass, and keyboards. Almost too loud. It's crazy how big it sounds for two small amps.

[@hoboroadie4623]

@@jamiebarr9810 I have a different basic rig that I call the Cerberus. There's other stuff, the Brotary and the Echo Array and cetera, but the basic Cerberus is one small amp running a little Vibrato, and two larger amps running dry through a Panning Tremolo. ATM I have a little bedroom rig with one twenty Watt Virtuoso and two thirty Watt Conquerors. Sometimes I run different sorts of Amps off the Tremolo, I am getting a UL760 that will sort of match Tremoloing against one of my Defiants, over a wet Conqueror. And the farm is hopefully about to thaw out enough to get out there and hook up the big iron. 👍

[@johnpierson8398]

Yes, this video is absolute gold! I'm an EE and and an old guy and have been playing guitar for 50+ years. What I really think is great is your clarification of polarity versus phase. The terminology is mixed up in many peoples understanding and how products don't always use the terms consistantly. And in this world of awesome digital effects pedals, the analog dry through issue is now becoming a common issue. I recently bought an Eventide H90, which I think is quite incredible. But in a recent episode, I heard Mick say the lack of analog dry through made it a non-starter. I now understand why this does not work in a "TPS Dual Amp config". The H90 is still awesome, but not in all configurations. Eventide claims that they had more phase problems with with analog dry through and therefore did not implant this in the H90... Super great episode!

[@ThatPedalShow]

Indeed. And there’s merit in Eventide’s argument when you get into some of the incredible stuff it does - pitch shifting especially. But exactly as you say it’s all about context.

[@timothymeyer602]

Got maybe a stupid question. Are there safety issues with one guitar thru 2 amps? I ask because years ago I got zapped by the PA system

Hi Mick, hi Dan. I've recently been watching your episodes on wet/dry and wet/dry/wet rigs, so this episode has come at the right time and is the icing on the cake. Definitely going to try it out. I've pretty much always had a couple of amps, but only ever used one or the other as my "Go to amp"... but from now on it will be... "Go two amps!!"

Struggled with an old nemesis doing wet dry setup at one point. No one could explain what was going on. Was dealing with the latency because it wasn’t dry through. Glad they fixed that.

[@claytongouin5605]

Great episode. I've been using your videos for a long time to play around with my own hybrid stereo and wet/dry/wet rigs in my spare bedroom studio. While I was aware of issue of polarity and phase, this really helped me understand some problems inherent in different pedals and why issues of signal routing might not always be as simple as flipping the polarity.

I've been running two amps for years with the Fulltone True Path ABY switcher. It has a "Phase" switch. Nope, it's polarity. Thanks for the clarification. I work for an electric company in the US and have studied phase and I never realized it was actually polarity. Now you need to explain to everyone vibrato vs tremolo. I had that wrong for years too.

This video comes at a very fortuitous time as I’m in the process of yet another pedalboard makeover. Will definitely be digging into the specs of any potential pedals to join the party. I’ve yet to jump into playing out with a wet/dry or stereo rig but I love the idea of it, so keeping it as a potential option is always at the front of my mind. Once again, many thanks for your years of service. So much incredible knowledge offered up to us and I’m so very grateful. Cheers!

[@scottcurry4116]

I love this show! I’ve watched every two amp show you’ve made and I learn something new each time. I’ve run wet/dry for about a year due to TPS. Analog dry through explains an issue I have with the Strymon Flint. The reverb is analog dry through but the tremolo isn’t. So when I use the reverb, it sounds great, but the tremolo always sounds off! Thank you! Lastly, I have the Humdinger and it is awesome. I had a Lehle Little Duel II, which was nice, but the Humdinger takes up less space, is less expensive and its buffer adds a clarity that the Lehle didn’t. I also have a Wetter Box coming in a day or two for more fun. Thanks again for your shows!

[@danottley2627]

You finally convinced me to play with my polarity even though I thought I was in phase all the time. Well.. Turns out I was wrong! I used the inverter module on my zoia to flip the polarity, but once I found out I had to flip it I just swapped the two ends of the cable to my speaker.

[@kevinlt143]

Love the fact that while this isn't solely focused on bedroom playing, it does add an amazing depth to the sound that is hard to otherwise come by! My biggest issue here though is both my amps are solid state (not inherently bad, bear with me!) with lots of headroom. I boost into a low gain drive, and instead of more gain, I get more volume (and a bit more gain). I'm not driving the amp, pedals have high headroom, it's a an interesting "bedroom headroom" problem (to sort of steal Orange Amp's coined terms).Would love to see some episodes exploring bedroom tones (there have been a few over the years...)

You can also go wet/dry/wet with that combo: Use a humdinger or similar to split after drives and any mods you want to go everywhere. Send the dry to the AC15 and the isolated out of the humdinger to your wet effects, running stereo into the JC40. I prefer to kill fry into the wet amp but see what you like more!

[@unclemarsguitar]

Lovely video on the foundational fundamentals -- it was this channel that got me into TPS wet/dry (and w/d/w) years ago, and since then I've run into seemingly every conceivable problem not covered by this video -- we need a followup! On: 1. The difference between transformer isolation and simply lifting the ground on one leg of the split signal. "Ground lift" switches disconnect the SHIELD of the signal cable and expose it to all kinds of EMI/RFI noise that is often WORSE than just the ground loop hum. 2. How/whether it is possible to eliminate loop hum AFTER a stereo pedal that is only mono in > stereo out to two amps. MOST stereo delays/reverbs are actually mono (one channel) DSPs -- they sum the stereo input signal as part of the analog to digital conversion, which can create its own share of phase headaches! How do we, you know, ACTUALLY USE stereo-out pedals with two amps without hum? 3. The problems that are introduced if you send your isolated leg of the split signal through other pedal(s), rather than directly into the amp. This is especially troublesome because pedals dump their noise to ground through the cable shield and when you plug in an "isolated" ground-lifted signal cable with the shield disconnected, there is nowhere for that noise to go except into your audio path! So how do we get a split signal chain with different effects on both sides of the split (rather than just one) without any noise/loop hum? Does the isolated leg of the split ALWAYS have to go directly to the amp? These are the problems anyone who ventures down the glorious 2-amp path will inevitably run into, and sooner rather than later. Would LOVE to hear how you leg-ends deal with these scenarios!

[@ThatPedalShow]

1. Too complicated to worry about in rock’n’roll. Mick here. Dan has solved it on his latest gen GigRig products (they’ve moved away from transformers) but it’s something that’s never bothered me. And most shit //really// bothers me. 2. Just put the Humdinger, isolated side only on one output of the stereo pedal. Solved. 3. Been running wet/dry at 100-200 watts for years, and never had a problem with this because a) I use Dan’s power that is properly isolated and never has any noise and b) use good quality pedals that run silent on Dan’s power. The isolated leg can go through other pedals as well, as long as their power is isolated too. Hope that makes sense!

[@lightonthelandscape]

Wow, that was excellent. Before watching your "Wet-Dry & Wet-Dry-Wet Amp FX Setups Explained video, I had a Radial Big Shot ABY - and I previously have split the signal at the end of my signal chain into two amps and left it at that - it simply beefed up the sound with delays and reverb going through both amps. It's fine but It's you mentioned, it can get a bit mushy with bigger delay/modulation effects. Splitting wet/dry (splitting before modulation/delay and reverb) seems to creates clarity - less mush and I feel it has a bigger sound for some reason. Really interesting. I use a vintage Deluxe Reverb (silver face) and Little Walter VG50 amp. Sometimes I use the DR with a Vox AC4 HW1 for a very different tone at smaller venues. Killer sound. Without you guys, I'd still be living in the land of Mushiness without knowing how much better it can be to split the signal wet/dry. Thanks guys.

[@mattg082]

Splitting is great to wet/dry! I have an ABY BABY I’ve tried at the very end, and then also as a split before effects. Wet/Dry…I use a Sky King(Fender circuit) and a Ampeg VT40 for the more distorted big parts. Sky King is wet/Ampeg only boost and distortions. I found the same as well! Having dual mono with both wet, can get mushy unless you can tap dance fast. What I like is being able to have a nice clean wet Fendery tone going on. Then when I want dirt, just tap B on my ABY…all effects are gone and I have a great beefed up tone. Personally, I don’t always run both amps on at the same time…even with wet/dry. Unless they are of similar cabs, and amps styles. It causes one amp to sound good volume wise, kicking in the second it’s too loud on stage. Then you turn both down and using one or the other….now it’s too low. I’ve settled on just A/B for now…but still run wet dry, as it’s way less pedal tapping. Also found I need far less dirt pedals this way. But for gigging purposes, I keep a lot of drives as I’m not lugging two amps often. Just for studio use, practice or a big show. But def the way to go is to split it wet/dry for more diverse sounds, and less tap dancing or using a very complicated routing system to program. A lot easier than turning off 3 stacked wet pedals, and then turning on your distortions for one amp.

[@rayrifice2595]

Mark Knophler was around Billy Gibbons once wanting to know how he got his fat tone so he could use some special sauce on Money For Nothing. So Billy would not tell Mark. So what Mark did is he had one bad ass amp he put in a soundproof box and he mic’d it up and ran that signal through his board and to his other amp. Then later on Billy Gibbons asked Mark Knophler how he got a fatter tone than his and Mark wouldn’t tell him!!! 😂

This is such a valuable resource, and so well done. Thank you! I recently switched to wet dry for live and boy did I have a hard time figuring out what pedals flipped the phase when active.

[@ThatPedalShow]

Mmmmmm. Niiiice!

[@eingeschränktesLichtraumprofil]

cool episode! another big difference between phase and polarity is: polarity is not frequency depending. everything is just mirrored on the time-axis. out of phase is frequency depending. if the latency is i.e. 10ms which eaquals 100Hz, everything that is n*100Hz is amplified and everything that is 2n/(n+1/2)*100Hz is eliminated.

Thanks for revisiting this chaps. I don't have two amps, but i do have an amp with an attenuated output and i run it alongside a plugin "amp". My version of wet/dry, but a bit more attainable 😊

I play at really low volumes at home and honestly having 2 amps is a great solution. Lush full sounding vibes at lower volumes. Right now I am using the HX Stomp to manage it but before that it was a Radial Twin City which is a GREAT pedal.

[@mattg082]

This is one thing I realized…if at home you’d first think two amps will be double loud. But in reality having say 2 Roland Jc or whatever…you can get the volume very low, while still enjoying it! Also not bother anyone as much as pushing one single all louder. I don’t do stereo in the studio, but I like running stereo at home on two small amps! It’s quiet and just like listening to a stereo at home at tv volumes. Fuller and less volume to turn up.

As an audio engineer I love having a ton of control over the mix of my wet effects in my overall sound. I paired a Goodwood Audio Interface (sorry Dan) with my board to allow me to go to two amps without any of the gremlins that come form running two amps. But it also lets me run my signal in mono if I want to just use one amp.

So well explained and makes sense of why it is such a minefield if you don’t know what you’re doing… (Like me!)

[@mikmc]

Ive bought and sold a few really nice amps over the past few years (only ever owned one at a time) amd recently got "the amp", a Hamstead Artist 20 and have been very happy with it. Now after seeing Dan demo a 2 amp set up at Pedal Empire in Brisbane in December and now this video, im on the lookout for another amp 🤦‍♂️🤣 I have a UA Golden which has analogue dry through so guess ill try that method first. Thanks Dan and Mick for spreading the word of the lord (the tone lord)

[@LockRocker]

It's official, many of us are unphased by this video. Such good work is likely the result of having a secret Lab!

[@richardcrowther8568]

Fantastic video, learnt loads, I was a bit confused on polarity and phase, not any more! Thanks guys

[@willwetherington]

Well, don't I feel dumb. You mean to tell me I could've been doing this the whole freaking time? I just tried that amp to amp method and Holy Shit it works. Thank you so much guys! I guess I got super lucky. No phase problem and no hum.

[@anthonycarvale]

Me too! 68 Deluxe Reverb Reissue and an Orange Super Crush 100. This is so fucking cool lol

[@curtisivie8535]

Great video. I want to try to do a wet dry setup, but it has always seemed too much for me to deal with at the very outset because I don't understand polarity and phase. This is the exact kind of video I needed to give this a shot and feel like I have a chance at success.

[@pabcrane]

What a brilliant episode; Mick and Dan you do this type of exploration of a subject with a fabulous mix of didactics and practical demonstration so well. I started experimenting with wet/dry/moist/stereo options after seeing your videos over the last six years (!) or so. It opens up so many sonic opportunities and as you've shown consistently it can be fantastic mixing two different amps into a gestult entity. Something else I've been experimenting is using two Laney LC15Rs - one with a Celestion Gold 10 and the other with a Greenback 10. It's been really interesting to hear how these speakers interact with all else being equal. (And as one amp is silver and the other black they look pretty nifty together as well!) Apologies for lengthy comment but i do want to thank and congratulate you on a well-done video, it really consolidated the information I already had perfectly.

[@ThatPedalShow]

Nice one Paul. We bet those two Laneys sound cracking together!

[@StrymonPyman]

Thanks guys. That’s really helpful and informative. May have to give it a couple more run throughs to get my head around it fully!

[@cmoore484]

That was gold. I have been using stereo outs on pedals for 20 years. I’m gonna have to get a humdinger

[@pauleddy5146]

Boys, you can reverse the polarity of one cable too. Needs a specially made cable where you switch +/- polarity on the cable end of one side. I must add, sorry, that this can happen with manufactured cables and you'll be chasing your tail trying to find the problem . . . until you use another cable that you KNOW is wired properly. You can then mark that cable as reversed polarity and use it to remedy reversed polarity issues where a single cable would make it an easy fix.

[@billtravis523]

Good to know for future troubleshooting!

[@johnfrewin7717]

In a world of super high end boutique gear, the magic box that makes TPS wet/dry possible is really affordable,I have a Humdinger on ( actually hiding under)both of my boards ,and can say that I expect them to stay there despite every other Pedal getting swapped out over time- many thanks👍🎸

[@sesa2984]

This just came to my mind, but not having a good stereo in my house, I have small radios. One time I noticed that when I turned on one small radio, another was still playing, tuned to the same station in the other room (very nearby). It sounded AMAZING. Just combining the tiny frequency ends that each 2-3 inch speaker didn’t share made for a really full and pleasing tone. So I think combining two (or more) already good sounding 12 inch speakers must be amazing. I’m ready.

[@billeblen5176]

thanks oh so much. been thinking about trying a two amp set up and what you have discussed has been an eye opener. keep up the great work.

[@jonathanmackie4884]

Beautifully explained gents. I now understand exactly what I need to do to solve all my dual amp issues... sell all my gear and buy a motorbike!!! Just kidding (ish). I am an og viewer from back when you started. Unfortunately medical issues have put paid to my playing, but when I saw this I had to watch as I got into the 2 amp thing from watching you guys and it was truly awesome. Couldn't play worth a damn but my tone was top notch. Nice trip down memory lane with the push me pull me dance...

[@jsarty54]

Been running 2 amps out of the back of my boss ME 80 for couple years , love it !

[@SusanBadura]

Mick! Nailed the intro. Loved the TL;DR, but I’ll go ahead and watch the whole thing. 😊

[@tonyz4292]

Great episode!! You guys ever do a episode about the difference in tone between 8/16ohm speakers- been down this rabbit hole lately, bought the same speaker in both ohms and I swear there’s a difference, am I losing it?!

[@ThatPedalShow]

Nope. You’re not losing it. Totally a thing!

[@rocnpops62]

Thanks so much for taking the time to explain this so thoroughly. Much appreciated guys.

[@spharr]

Excellent video as always. Thank you for taking the time to demonstrate that lag caused by digital effects owing to A/D and D/A conversion - which I'll come back to later. One thought re polarity and phase. It seems you are mixing cause and effect here a bit. A switch in polarity (using the 2 speakers example) causes a phase shift of exactly 180° between the sound waves coming out of the speakers. We all understand 180° as a flipping over or half turn. So we name that effect we hear when we change the polarity as a 'flip in the phase'. Changing the polarity can occur in many parts in the signal chain, as you demonstrate. What you can do with a digital stereo delay to get a TPS wet dry effect and avoid that annoying phase shift owing to the A/D conversion is to use a L/R stereo delay but set the effect mix of one of the channels (e.g Right) to 0 and this goes to your dry amp. This way the 'dry' component of both channels is still in phase. Obviously not as ideal as analogue dry through but a compromise that works.

[@JDon8110]

Epic. This vid made me want to comment. I've been hearing you talk about 2 amps for a bit so I tried it a few weeks ago. Wow ! It's probably the most jaw dropping enhancement to guitar I've tried. My second amp is a crappy practise amp I had lying round so it almost doesn't seem to matter what it is. Just blending in a different sound and having some width is superb. My only wonder is it less focused in a band situation where perhaps a tight focused sound may fit in better with the rest of the band

[@ThatPedalShow]

Depends on the band. Very dense mix, maybe it’s too much. Smaller band with people who understand light and shade - there’s NOTHING better!

[@jwhouwers]

I’ve learned som new things again, thanks guys!

[@rogereijk2612]

Thanks Guys, this is one I was waiting a long time for 🎉🫶 Thanks to you I was already doing a good job by using a splitter with isolation / phase switch. I am using the TPS dry wet method, using a Brunetti Mercury EL34 and a Marshall Valvestate. They sound great together, although I’m thinking about swapping the Marshall for something else … The analoge dry through thing was new to me, luckely my Strymon pedals (Timeline, Big Sky and Mobius) all have it. I hope it’s always on, I have not checked the settings 🤪😂. Thanks again and keep up the good work, its very much appreciated 🙏🫶

[@emmettpavey8318]

I love using two amps. lately I have been running an orange tiny terror and orange ad 5 both with 12ay7 in the first positions. just a glorious sound. I use a Lehle dual sgos to manage evrything, works great.

[@eearts]

Great SPIRITUAL discussion guys 🎉

[@Killer-Machine42]

came here to see how to fix my "fx mix" polarity problem on my Marshall TSL (knob mixes dry signal with fx return signal for wet/dry adjustability), and also learned why some of my pedals changed my tone when I didn't want them to. very educational

[@samuelhatman8995]

Two excellent players gift the world with Guitar Craft's Technologies down to the level of Nuance! They then proceed to demonstrate in nearly laymen's terms, the need and effect of the knowledge applied properly is Profoundly Profitable, Enjoyable, in Beautiful Tones! There... Dan and Mick... my gratitude sincerely! I see below, I am not alone. Thank you gentlemen. Merch time!

[@sebastienboisvert3268]

Great stuff....been using 2 amps since forever. I think I got it right but this vid really clarifies a lot of stuff. Thanks

[@LouisMalagodi]

Great video, this stuff is hard to explain and takes years to wrap your head around. Two terms I think were (understandably) missing in this video, from a sound engineer POV, were 'Phase Cancellation' and 'Comb Filtering'. Phase Cancellation is what you hear when one source is out of phase with another. Different degrees of out of phase and how similar the sources are will determine what frequencies are cancelled. Two exact same signals with one 180 degrees out is complete cancellation. Comb Filtering is what you hear with Mako D1 going to one amp. Comb Filtering is frequency cancellation when there is a millisecond delay on one of the sources. The amount of milliseconds will determine what frequencies are cancelled (_hz and every octave of it)

[@ThatPedalShow]

Thanks for this Louis!
