Sadly my SB14 has met with a terrible end, and I am parting out the body parts. I have a complete circuit including 3 band preamp, 3 position switch, battery box, humbucker pickup with phantom coil, input jack, chrome knobs. Includes all screws, and I will provide a diagram of the wiring, and tag the battery and ground wiring for easy assembly. Great for a project bass or to upgrade a passive MM style bass. $149 gets it to you. I'll cover the ship in the CUS. PM Me if interested. Pix to follow. Pete.
