Now our guitarist wants to couple 2 amps together. one is a peavy and one is fender. Now bearing in mind that he wants to use either or both of them at the same time. I know Boss do a special selector switch but is rather expensive here in france.

So it over to you all for your welcomed guidance.

Cheers then

One or the other is easy, any ol A/B switch will do it...both together will create the need for volume changes to keep the level consistent...

A lot of the A/B boxes over here seem to let you select one or the other but not both (god knows why the french have to be different- no comments please LOL)
I'll dig a little deeper

I know that the volume will be a problem, but both at the same time will be for added punch and solo parts when needed

Cheater's way, is on an old fender, there's two inputs per channel. Plug your guitar into input 1 of channel 1, and connect a cable from input 2 (of same channel) over to the input of the second amp. He would have to reach over and change volumes by hand, but it works quite well.

If they have differing stages of gain, then they may be out of phase with each other, but I doubt very much if that would pose a problem with two different amps.

Me thinks, also, that once you get it going, it'll be both on all the time. Two amps sounds WAY better than one. Once he switches back to one amp, everyone will be wondering why the sound went thin.

The last guitarist I actively gigged with had two amps, one for high end and one for low end...I still want to push him down...

An A/B/Y switch is what you need. Morley makes the one I've heard about the most.

Yup, that's the one I use for this exact purpose . Built like a tank, that puppy is !(unlike their wahs, which I've been through a couple of.)

TAd, thats the one I used as well. But indeed the trick pjk mentions is a great work around when ya need to tie 2 amps together. Works with Marshall as well as several others. In the day before big PA systems that was how the big guitar sounds in stadiums got done. Tied a stack of amps together with a stack of cabs and your good to go. I never got past the 2 amp 2 stack phase. That was more then loud enough.

Hi peeps,A good way to stop buzzing and earth loops is to stick an instument mike in front of one amp into the other.Ive always found that cable/amp coupling seems to take some of the signal off the guitar and even if it doesn't you think it does.

i wouldn't reccomend the morley a/b/y. i tried to use it in an a/b/y setup for recording and found that it introduced a horrible noise into my signal. i now use the radial tonebone jx2 pro switchbone a/b/y. it costs a lot more than the morley but it's about 10x the product.

just thinking back, I was playing in a basement with a guy that was playing through a champ, and a bronco. The sound was great (for a basement). Both were overdriving, and a little reverb from the champ, it sounded great.

just thought I'd share that =).

You could get a stereo delay pedal (mono in and stereo out) and then on the left out make a home made on/off pedal or something.

Stereo chorus pedals have the two output thing and sound great with two amps,but does the crowd notice after six pints.

I used to do this with an Ernie Ball Stereo/Pan pedal. The pedal all the way back would be one amp, all the way forward the other. Or, there's a switch on the side that switches it to a regular volume pedal and allows both amps to be on at the same time. You'll probably need to lift the ground on one of the amps to get rid of ground loops.
