The Seymour Duncan SJB-3N Quarter Pound Jazz Bass Neck Pickup plants balanced Alnico 5 sound in the neck position, and that's alongside the powerful output and tight attack of an overwound core. Basically, this is a souped up J-style pickup, so your getting that flavourful vintage J-style sound but with a bit more spice and boosted sustain. This hand-built pickup has been wax-potted and features an RWRP design to counter hum when teamed up with a bridge pickup, making it a solid upgrade for any American J-style four-string bass.
