I want to put new pups in my Epiphone Explorer - yea its a cheap bass, but I like playing with it. Right now it has two volume knobs, a tone knob, and a pup toggle switch. I pretty much always play with both volumes full on, so I'm wondering if its possible to wire the volumes in series so one volume knob controls both pups, still use the toggle to switch between them if needed, then use the other two knobs for a treble/bass controls on a preamp, such as an OBP-1. Whatcha think? Oh and if anyone has any good pup suggestions ... I was just planning on putting in EMG's.
