Freuds_Cat Posted February 13, 2008 Share Posted February 13, 2008 (edited) I've been given this 80's Seymour Duncan Jazz Pickup by a friend and I'd like to try it out in my SX. My problem is that I cant find any info on it, even on the SD website. Can anyone ID the model for me, and even better can anyone find me a wiring diagram? It would be nice to actually know what the rocker switches did as well. I assume phase reversal, roll off filters, coil tapping or somesuch.

Hamster Posted February 13, 2008 Share Posted February 13, 2008 (edited) SD stopped making these switch pickups 'Active EQ' in the mid-'90s. They were replaced them with the Pro-Active series. The little rocker switches on the Active EQ pickups change the sound. Switch 1 shifts the coil resonance. On a Jazz Bass neck pickup, the resonance moves downward from 22 KHz to 6.4 KHz. On a Jazz Bass bridge pickup, it moves downwards from 17 KHz to 4.9 KHz. The effect is to give a more focused sound with a harder attack. Switch 2 gives a broad band bass boost of 4 dB for the Jazz Bass neck pickups, and 5 dB for the Jazz Bass bridge.

Freuds_Cat Posted February 13, 2008 Author Share Posted February 13, 2008 Thanks Hampster, I did find that wiring diagram but was thrown off by the rocker switches. My SX is a PJ config, so I guess I need to find an active Seymour Duncan P pup. Quote Link to comment Share on other sites More sharing options...
