I need some help figuring out my signal chain for a festival show tomorrow. I usually go ampless, and the chain looks like this: Bass > pedalboard >>>Aguilar TH pre (DI to FOH)> EQ pedal (for in ear bass mix) > right channel of Sennheiser G2 IEM (L channel for monitor line). Since I don't have a signal splitter, how could I add a 4x10 + amp (GB shuttle 9.2) to that setup, potentially omitting the Aguilar preamp pedal, because of redundancy? Could I go, bass >pedalboard> amp >>DI on amp to FOH >>> headphone out >EQ > workedwi IEM? The key is that I want to have control over my own volume on the IEM mix, I have the Rolles pm351 for wires situations, but I'd like some solution for the wireless +amp idea.
