Humbucking upgrade adds output and quietness. Great for pop, blues, classic rock and heavy rock.
Uses dual Alnico 5 blade magnets for more power and sustain. Both neck and bridge pickups will increase output and expand the tonal range of a stock bass. Comes with four-conductor hookup cable. Calibrated neck and bridge set. The bridge pickup includes a special phenolic surround to improve the appearance of the bass. The bridge model is designed for the 4003 bass and replaces the "horseshoe" magnet. The original chrome mounting ring cannot be used with the SRB-1 bridge model.
