As the Precision bass evolved, the early Tele bass single coil was replaced with a split-coil humbucking design in 1957. The '58 Split Coil P is based on the slightly later split coil design with flat profile, hand bevelled, Alnico V magnets arranged across two coils with opposing wind direction and magnetic polarity to cancel out hum. Scatter-wound by hand with 42AWG plain enamel wire, the tone is stronger in the bass with a more controlled high end and slightly scooped mid compared to the earlier single coil. Characteristic of the later '50s P basses, there's more output on tap for a muscular performance with exceptional punch.
