I have a Brand New BTC Control never installed. Knobs, wiring and box. Make me an offer. I bought it for $75. Also, BRAND NEW never installed B30Q 3 band EQ system(3 pots). No knobs included, but this system uses regular knurled pots so any knobs will work. I may have some laying around I can throw in. This is a special order EQ. I bought it for $75. I sold the basses I was going to put them in. Make me offers.
