The Lindy Fralin P 4 pickup you will hear below is intended to be a replacement for a Fender Precision Bass style pickup, with a few advantages. Namely, a very loud and clear tone thanks to its alnico 5 magnets and heavy 42 gauge formvar wire.
These pickups are hand wound to vintage specs (10 K).
More information, pricing and dimensions are here.
Sounds like…a P Bass. Fralins are great IMO
