Ok, I'm no effects guru. My board is currently L6 G-50 - tuner pedal - SCR-DI to amp. Lately, my one band has been playing as a 3 piece (4 with/lead vocalist who does not play an instrument). I saw a thread about doubling your bass into a guitar amp, after bumping it up an octave and I'm interested in giving that a shot to fill out the sound a little more when guitar plays solos, as there is some dropoff on some of the songs we play. Does anyone have any good tips for a signal splitter, as well as an octave pedal to accomplish this? I have a spare tuner pedal, some guitar effects, and a pretty ok tube guitar amp - I just need to get the signal split and raised an octave... thanks in advance!
