Hey Bongo,
Maybe this is a stupid idea (
and if it is I'm sorry for even bringing it up) but...
Why not try one of those
OLC Umble kits 1st? This way if you could mod it during construction to be better suited for bass. Also if you like the sound, you know you're onto something, but if not you could prolly sell it off either here or @ TGP and recoup your cost for the kit w/o having to worry about too much $$ depreciation since you bought it in kit form and would be selling a completed pedal.
