Ok guys here's my situation and what I think my solution is, but I'd like to hear suggestions. What I've got: A dedicated bass rig and a dedicated guitar rig. Bass is Mesa Big Block 750 with 610 Powerhouse. Guitar is a 1970's Peavey Mace 212 combo. What I want to do: Clean full signal to bass rig, mids and highs only to guitar rig. Dirty nasty without loosing bass and articulation, plus high gain feedback potential. Think along the lines of a Chris Squire setup, but without the stereo bass. What I think the solution is: Bass->Crossover->signal is split in two, one line to input of each amp. My question: What would be the best device out there that will allow me to split my signal like this, sending most freqs to bass rig while cutting out the lows to the guitar rig (basically two independent channels with plenty of control over which freqs go where)? 1/4" ins and outs. Thanks for the help, guys!
