Running two Amps with one Pedalboard - including Effects Loop

[@jimwilliams746]

Very clever. The effects loop send breaks the signal when you switch between amps. Effectively you are sending you signal to the amp but you can't hear it because it never returns to the amp.

[@kopan14]

how about running 2 amps into 1 cabinet with attenuator in between ?

[@warrenmooney9422]

I would be careful with that. Not sure what cabinet you have but I would recommend that you stay away from that unless you have a 4x12 cab and the left and right speakers are wired completely independent from the each other. Anything short of that I would just use two cabinets.

[@frankwebster9110]

Thanks for this video! It's great to know there are others out there pushing whats possible!

How could i hook up two amps with one pedalboard and only one of the amps has an effects loop?

[@projectmonk9673]

Once you have both amplifiers connected through the ABY pedal, how do you change amplifier channels at the same time???

[@azjammin6663]

Yes this is my question

[@badoverman]

What if you want to have the fx loop on with both amps at the same time?

[@GuitarsAndSynths]

I have a Morley ABC Switcher pedal and have a question. How do I send output of my pedalboard that is connected to input of my amp to the pedal? Sorry to ask a dumb question but the inputs only allow one cable from each amp. I want to send pedalboard-> amp-> Morley switch pedal input A and then on amp 2 send output of pedalboard 2-> amp2 -> morley pedal input 2.

[@orangerecords_studio]

is it somting I don tunserstand : i want to hear, and hvae siganl from both ! amps, now just one and one. So how does that work =?

[@D3THR0K]

It seems to me that this pedal can only play A or B separately. Is is possible to use both amps both A and B simultaneously? So that both amps are using the same FX loop at the same time.

[@duchyofdrive2922]

Hi. Yes, this is only a either/or solution. If you want to run both in parallel, I guess you would have to put in more budget to avoid hum problems.

[@D3THR0K]

@@duchyofdrive2922 any suggestions?

[@duchyofdrive2922]

Can't think of a stock product. Maybe try looking for a stereo AB/Y. Otherwise going custom might be an option. Have good experiences with dscustom.net.

@@duchyofdrive2922 awesome, thank you!

[@rzapol]

If anyone is still paying attention gonna reiterate a previous question. With a passive stereo splitter should I expect volume and or tone loss?

[@duchyofdrive2922]

Hi. Sorry, missed your previous question. For me, it was fine. Didn't notice significant changes. At least none I couldn't get rid of by tweaking EQ and volume a bit.

[@jimhoman4415]

A wiring diagram would be awesome. it's a little hard to follow without seeing where you were pluging in on the amp side.

[@derek9658]

agreed i am lost

[@jordicuello2410]

Cool video, many thanks for sharing. I bought the Palmer Tino to switch my amps, but I did not consider the fx loops to split modulation pedals. I wonder if I can do the contrary you did, I mean that the main signal will be managed by the Palmer Tino, and for the fx loops, I’d like to try with 2 double jacks: one to connect to the output of the last modulation pedal to both SEND fx loops, and one more double cable to connnect both RETURNS to the first modulation pedal. Do you guys think it could work??

[@guitarelic]

Thank you for the video. I do have a question. In case a multi effect guitar processor has only 1 output which means I can't use 2 Amps if the Amps doesnt have an fxs loop (4 cable method). So can I get a "Y cable" to use that on my guitar Multi effect processor and its going to be connected from it to a (loop station) or whatever device that has R & L and thats going to split the signal to stereo, is that correct? Example: I will have the input from the multieffect unit sent to a loop station R & L (input) and have the amps coming out from the loopstation as stereo out R & L.

[@duchyofdrive2922]

Hi @Guitarelic. If I get your description correct, a simple A/B Box should do the job for you.

[@panicrev555]

Or you could put a stereo pedal after the distortion to split the signal and use stereo effects in and out of the two effects loops.

[@1978ronin]

Does this works if one of the amps doesn't have and FX Loop?

[@jezza46]

I’d like to know this as well.

[@marfio0584]

Hi there! How do I know if my amps have a serial or parallel fx loop? I ve got a Marshall 2000 dsl 50 and a Carvin combo club master 112.Thanks!

[@duchyofdrive2922]

Hi. If your amps have a pot where you can adjust the amount of effect in the signal, these are parallel effects loop. If not, it is most likely serial. With a parallel effects loop, you can try to adjust the effects level all the way up. This should cut the dry signal and make the loop more or less serial. But some amps still route some amount of dry signal even if the effects level is all the way up. Guess you will have to try without effects plugged in. If the amp is silent when having effects on full, it should work with this method.

[@marfio0584]

@@duchyofdrive2922 Got it.I have no pots on both amps so hope they are serial. Thanks

[@marfio0584]

There is only a loop level button next to the fx loop on the jcm 2000..

[@adamrepetowski4573]

What if I want both amps to run at the same time and both loops on/off at the same time.

[@duchyofdrive2922]

That would be much more difficult and more expensive. Especially if you want the loop effects routed to both amps at the same time. I looked for those switchers and couldn´t find one. Closest thing would be the Ampete 222, but with that, you can only route the effects to one of the two active amps (wet/dry).

[@michaelpiercey7316]

@@duchyofdrive2922 To add to this. Im trying to think of a way to run my Twin reverb, Into my super six (which powers a leslie) , into my dual showman. I’ve seen some pedals from Lehle that offer three amp switchers. But is it even possible to have the three amps on and effects loops and all three amps going at once? Or would this require some wacky 3 headed cord and some modification to the amps?

[@Jeff4014]

@@duchyofdrive2922 i dont really get what you say?... isn't just enough to buy the first white device that you showed in the video and then for the fx loop buy the black one and run both devices at the same time?

[@aljuric5887]

Duchy! Please help! Hitting the Onion switcher everytime i want to engage FX Loop in other amp is extremely inconvenient when going into/out of a solo. Would it work if the switcher was permanently engaged? So when i switch amps on-the-fly the FX Loop is already angaged on the other amp.. Please help! - Love your work and thankyou for it 😊

[@danielmsignorini]

Also I have another question, is there ground loop issue with this setup? Any hums?

[@duchyofdrive2922]

Hi there, for the tuner and drive pedals, I just use a Y-cable after the last effect in front of the amps. Since the switcher cuts off any signal in the effects loop of the amp that is not in use, those are muted as well. I also didn´t have ground loop issues with this setup.

[@marfio0584]

Hi! Did you notice some signal or frequency loss in this setup? I wanna try to send a couple of pedals (strymon flint and a way huge delay pedal) in both fx loop of a Carvin club master combo and a Marshall jcm 2000 head. I didnt really understand about serial or parallel fx loops in amplifiers..It can work in both cases? If this works as I hope, you let me save a lot of money!! Thanks for this video🙏

[@andrewclark6578]

What is the brand of the switcher?

[@duchyofdrive2922]

They are called "Bright Onion Pedals"

[@timgoody1]

Hi - great video, really useful. I wondered if there were any issues with losing guitar signal strength with the y-splitter cable? If so, is the answer to use a mono AB for the front of the amp instead of the y?

[@duchyofdrive2922]

Hi @Tim Goody. I never had any issues with the Y cable. I used it to avoid an extra step on the pedalboard. I guess you could test the setup for signal loss with an ABY switch.

Hello, great video! Would it to be possible to run one pedalboard into two effects loops? I have a Mesa Boogie JP-2C and Peavy 5150 and would love to figure out how to use both effects loops at the same time.

[@duchyofdrive2922]

Hi there. Should be possible with some kind of stereo ABY. Can´t find one after a quick search, but I guess you can have one custom built. Maybe there will have to be some kind of ground lift on one of the channels....

[@soulicide8150]

Hey Greg the answer is yes. I currently run my Mesa mark 4 and my EVH together with 4 cable method for each amp using 7 cable method running stereo. Check out plague sythe studios here on you tube. “7 cable method “ or “4 cable method stereo “ is the tittle. Highly recommended channel. Ryan really know his shit and has some awesome content you might find useful

[@personalfreedom2700]

Can you just use 1 stereo pedal that has 2 ins and 2 outs… and from the effects loop on each amp.. thus: *From fx loop 1 the send goes to input 1 of pedal. *From fx loop 2 the send goes to input 2 of the pedal. *From fx loop 1 the return goes to output 2 of pedal. *From fx loop 2 the return goes to output 1 of the pedal.

[@steveo4253]

I was thinking the same thing. Does anyone know if this works ?

[@danielmsignorini]

When using that switcher, do you still need an AB pedal from the tuner and drive going to the front of your amp or does the switcher do that too?

[@FrancisJulien418]

Danked sir! One question: I assume you connected two ''combo amps'' in this exemple? So you connected the two amps to your pedalboard and also chained the fx loops with your method. Very very nice. Now, if you only want to use ONE cabinet? Same goal here: pedalboard going in front and in fx loops of boths amps but with only one cabinet. (Probably needs one more XY pedal to switch amp1 and amp2 into a single cabinet?) Thanks a lot! Very instructive, I have been searching for this! peace

Hey dude kool vid...you were touching on some points where I’ve hit a brick wall In my own chain. I was hoping you could lend a hand. I’m trying to use my mooer ge300 multi fx amp modeller (going out of the XLR outs using 2x frfr powered speakers as cabs) and a katana artist in a two amp blend using and ABY to split both. The powered speakers sit either side of the katana... so 3 speakers are in play. This part is easy enough everything is split through the ABY... great I have two essentially .... But when I stomp an Fx on the ge300 it only comes out of the powered speakers. And like wise if I stomp an fx in from the katana using the GAFC it only plays through the waza speaker on the katana. How can I sync the fx of both units without phase issues ... but it is paramount that the modelling from the ge300 does not colour the artists dialled in preset and vice versa. I mainly want the katana to be a dry rig... I want the all the modulation delay and reverbs to come from ge300. But when I stomp the distortion and wah of the ge300 I want it to play out all 3 speakers. Like wise for the katana if I stomp in a distortion from the GAFC I want to hear it out all 3 speakers. Is this possible? Cheers.
