The Aguilar AG 4J-60 pickups are designed to have both clarity and warmth and will reproduce all of the dynamics and nuances in your playing. This pickup set is modeled after a mid 60's single-coil Jazz Bass® pickup. The AG 4J-60 uses all the period correct parts, including Heavy Formvar wire and Alnico V magnets. Aguilar developed a proprietary winding pattern to give these pickups great string-to-string consistency while sounding full and articulate. The pickups complement any bass and are a great match with Aguilar's OBP on-board preamps. Available as a calibrated neck and bridge pickup set (also available separately) for four string basses. Both, the AG 4J-60 single pickups and sets are direct replacements for Jazz Bass® style basses.
