Seymour Duncan SPB-1 vintage P Bass pickup. Virtually brand new, I bought it a month and a half ago and only had it installed 2-3 weeks. It's perfect, the hardware kit was never used or opened. Nice thump! From the SD site: Vintage P-Bass 11.6k n/a Alnico 5 rod 11.6khz. Classic dual coil P-Bass, circa '57-'62. $40 bucks, $5 for shipping.
