Our drummer, also a pro sound guy, OUR sound guy when he plays with us HATES my effects running through his IEMs .... so my first fix was to stop using them, then he didn't like the Spector Bass (Q5 w passive pups/active tone) when I messed with the tones. Fixed the tone issue by keeping them flat at 0/0 gain/loss. I agree they are a little weird. He loves the active Precision bass (shocking typical sound guy response). The two effects pedals I've alternated are an old (really old) EHX Chorus/phase shifter and a newer Digitech RP80 also while using the phase shifter..... My current solution is to split out the "clean" signal and send that to him, using two GKMB115s stacked, one clean, one with effects. Thoughts? new pedals or new sound guy?
