well i gotz these two amps laying around.
Acoustic 260 100watts

and
Peavey Transtube Studio 112 65watts

now, i would like to use both of these amps at once, how may i do this?
bi amping i think?
help a brother out here shortscale.

get something that splits your signal.

you might even have a pedal that does it already, i've got like three that can split one signal into two.

i'll look around for one of those..
but couldn't i just take a guitar cable and plug it in to an input?
b/c both amps have 2 inputs.
i don't want to fuck my amps up so i'll ask every little question before doing anything.
like the passive on the acoustic to the low input on the peavey and then the high input to my signal chain to the guitar?
(acoustic>peavey>big muff>danophobe trem>jaguar)

Do not plug the amps into each other, just plug into both the amps. That signal chain is backwards and doesn't provide any details on how the amps are hooked up, and is 3/5ths irrelevant (pedals and Jaguar). As best as I can figure it you want to send the balanced line out of the Acoustic head into one of the inputs in the Peavey, which will kinda work but sound like shit because it's all the wrong impedance and you've got superfluous amplifying/tone stacking going on.

Just get an A/B/Both box or a stereo chorus/stereo delay with 2 outputs and plug into each amp's input. I think you'll find it's largely pointless though, I've done this for fun with everything from a pair of solid-state 8" 15 watters to 2 Marshall tube halfstacks and it never sounds that good, just really rounded or powerful, really just introduces a bunch of new problems with the sounds masking each other as well.

josh is right in a way. with some amps you could just plug the guitar in one amp and then patch from the other input on the same amp to an input on the other. in many amps the input is just a parallel connection to the other input which in this case would have a guitar signal being sent to it.

the only problem is that here they're not just parallel inputs. they're Hi/Lo on the Peavey and Passive/Active on the Acoustic. so yeah, it won't really work right. you'll have use a separate splitter of some sort.

it actually works fine dude.
sounds wayyyy better than they did on their own.
way more balanced.
i've been experimenting by turning the bass and mid up on the acoustic and the mid and treble on the peavey
i'm still investing in a splitter nonetheless.

I think you can "jump" the two amps like you do on old marshalls

for instance, i run my bassman like this

Guitar > Bass input 1
Bass input 2 > Guitar input 1 [via a patch cable]

its a parallel connection and it runs both channels just fine. People have been doing that on marshalls for ever

I'd still recommend using a pedal with stereo outs though

interesting. so how are you hooking it up then? which amp do you have the guitar plugged into?

the acoustic goes into the low gain channel in the peavey, and the effects chain goes into the high gain channel.

ah ok, I guess that would work. the signal is probably just going through the initial pre-amp stage in the Peavey before it goes to the Acoustic then.
