Posted this once, but the only feedback I got was in direct conflict with the question... I know that there's a few of you out there who'll have some info to share on this. Even if you think I'm making a mistake by trying to go this route - please let me know? Anyone? ======= I have 2 amps that I love dearly - a Roland JC120 and a Rivera Knucklehead. I'd like to take advantage of both of them in my setup, as I've already experienced the frustration of too many tones into a single guitar amp (ie, ick.). I know that by separating various components of my looping, I'll be able to build a much larger tone palette in a single looping "event". This question really drives at 2 issues - 1) I'm looking for the right 2nd loop or delay tool that fits my needs and 2) I'm looking for ideas on how to best take advantage of 2 amps in my looping guitar setup. Today, I'm setup as: Guitar -> Dynacomp -> FM4 Filter Modeler -> Rivera Amp -> Rivera Effects Loop Out -> Digitech RP7 -> Small Clone -> EDP -> Rivera Effects Loop Return Occasionally other stuff sprinkled in there, but you get the picture I hope! I'm thinking that if I add another looper/delay in the effects loop, with some sort of A/B box for bypassing, I'd be able to decide what signal goes to what amp. For instance: Guitar -> Dynacomp -> FM4 Filter Modeler -> Rivera Amp -> Rivera Effects Loop Out -> Digitech RP7 -> Small Clone -> A/B Box A/B Box (A) -> EDP -> Rivera Effects Loop Return A/B Box (B) -> DL4? -> Roland JC120 (slave) Will this work? Anybody tried something like this? Specific to the DL4 and the recent thread on it being in the effects loop... is that a problem? I'd like to do this without buying a mixer and dealing with pre/post fader auxes, etc, as some of you do. If nothing else, I figure an A/B Box is MUCH cheaper than even a basic mixer with the features I'd need. Any help greatly appreciated!
