My wireless bass receiver (GigA Pro Pedal Set) actually has 4 separate outs: A, B, C(tuner), DI. And is programmable for multiple options activated by the stomp button (A, B, C, A+B, A+C, A+B+C, etc - the DI is always on). I run A to Amp+FOH, B to IEMs, but thinking of optimising the use so that DI (Pre) guess to IEMs and A, B go to separate chains, then either combining further down the line into the same mono out for all amps, or as you suggest to different amps.
Won't two different signal chains sound like two different basses, just as if there were two bases, each using one of the signal chains playing in prefect unison?
Thanks for mentioning the issues when recombining, I hadn't thought about that.
Over on the other forum, biamped was also suggested and gear examples.
Hadn't thought of using the effects loop return without the send, cool idea! I'll experiment with that.
Not a bad idea at all, full volume control of the mix too.
