i'm working on a similar setup for my rack... it's 2 preamps into a single poweramp. the "connection logic" for your proposed setup sounds feasible but expenses will range depending what goes in the chain and where the signal is going before it is amplified but it looks like you'll need a switching system and/or mixer.
-what is ur experience with this kind of setup
i'll let ya know in 6 months :P
-i am using a boss chorus ensemble to split the signal, do i lose a lot of tone doing so ( this is just to test it...)
if the fx does not have "true bypass", tone can be affected. I'd place the chorus somewhere in the FX loop. To split the signal to feed 2 amps at the same time, you can try:
a) buffered splitter
b) ABY switch
c) a long Y cable
that's only the beginning...
-would i run one amp clean, one dirty, and use the footswitch for the dirty amp??
clean amp can be disabled / enabled in conjunction with dirty amp disabled / enabled... depending on the midi switching system used.
-can I rig it up so i can switch both amps with only one footswitch (midi??)
sure... depending on the amount of relays available on the midi switching system, it can range from 2 mono relays to 4 stereo relays or a combination (unless you get it custom).
-is this a bad idea with only one cabinet ( my goal is not to A/B to different amps, I want to mix the 2 to get a thicker and unique sound..)
not a bad idea... I think the mixer will be in the FX loop and have the mixer's L output to amp1 return + mixer's R output to amp2 return. dunno if it'll work but it might be simpler if each amp had it's own cabinet however just to avoid a costly and more complex setup....
-can u tell the difference between delivery and d'journo??
sure... one doesn't come with philly cheesesteak
GAS can be a pita if ya don't know how to diagram your signal path first. You'll end up buying gear that doesn't maximize your setup's capabilities. I'd start off simple first (guitar -> amp1 + amp2) then expand and explore from there. I'd also start researching the manuals for the equipment that'll be placed in the chain.
Enjoy your experiments and share your experience. Feel free to PM me if you need help in gear recommendations.
