There's no model number on the pickup, but I've been told it's probably a Model P. Measures 11.11k. Per the previous owner, everything worked before he put the bass in storage. To honest I haven't tried it, and the price reflects so. The pickup isn't a concern, just possibly the preamp. Includes the entire harness w/ push-pull pot, tone pot, and jack, also pickup mounting screws. It will need to be resoldered and attached is the wiring diagram from DiMarzio.
