The 58CBP is the Fender Precision Bass® (P Bass® ) replacement pickup. They are highly respected by musicians and luthiers alike for their classic tone with more lows and low-mids. The two pickups in the P-Bass pair overlap each other by 3/4″ (19mm). The “Classic Bass” series bass pickups are passive designs featuring an extended and more resonant frequency range. They have far more “air” and definition at the top without sacrificing lows and low mids. They are cast in epoxy to remove unwanted feedback and microphonics.
