These are the Type 3 Alnico 2 (Dark Pleasant Distortion). I bought these to replace the stock Seymor Duncan Basslines that came in my Kurt Noveselic Gibson Rd. These are killer pickups I came across a set of old Bill Lawrence humbuckers that I decided to put into the bass. These were originally $125 a piece. Like I said they replaced a set of Seymour Duncan (passive) bass lines, to be honest the strings landed a lot more center of poles pieces on these than they did on the Duncan's. $55+8 shipping.
