Hi all, up for grabs is a near-new OBP-2 preamp (bass, treble) kit that already has the bass and treble pots pre-wired. Need to wire pickup(s) and remaining preamp wires to your own volume, blend controls etc. output jack, battery clip. Wiring diagrams included, very versatile options for several different knob configurations. Got it for a project bass that didn't happen. $76 obo includes free shipping.
