Based on Dave Boonshoft's personal 1963 and 64' Precision basses, this Aguilar 60's Precision Bass Pickup Set for 4-String Bass Guitars is designed to capture the vibe and feel of the 60's. Using period-correct heavy Formvar wire and Alnico V magnets, these pickups are specially wound to deliver the warmth and midrange "nose" that defines a great 60's P-bass pickup. Featuring improved string-to-string consistency, clarity, and articulation, for a clean sound.
