I'm rehabbing a '73 Fender Musicmaster Bass that came pretty much in pieces. Those all came with the Stratocaster Bronco type six pole PU. Based on how it looks like it fits the cavity and mounting base and cover fit it, the pole pieces appear to be too long. Maybe I'm just looking at something wrong. Anyway, I'd appreciate a length for the poles just so I'll know if these are correct or not and move forward on this project.
