The QP has a fat, punchy tone that pushes P-bass pickups past previous models with design and frequency improvements. The quarter-inch diameter pole pieces expand the magnetic field and extend the frequency ranges for a fat, full, punchy sound with tremendous mid-range presence and maximum output. Though often used for heavy rock tones, this pickup gives amazing tonal versatility, making it a favorite across the board in live and studio settings. This pickup is a drop-in replacement for any American Standard Precision Bass. Hand built in Santa Barbara, the massive Quarter Pound high output P-Bass pickups use ¼” diameter alnico 5 rod magnets, Forbon flatwork, and are vacuum wax potted for squeal free performance. Comes with black covers.
