I just got a SD PJ system off of eBay that is suposed to be completely active. Although there is no doubt that the pre-amp is indeed active and made be SD, I'm no sure of the pickups. Heres the email I just sent to SD's tech dept.: Hi, I have aquired a "New/Old Stock" active Seymour Duncan (suposedly) PJ system with Volume // Blend // Bass // Treble controls. Both the P and J pickups only have two leads ( Black & Red on the J, Black & White on the P ). The electronics have a Black box attached with a sticker on the back with: Duncan Designed 2Band EQ Bass Treble The Black box has numorous leads going to a white Din plug/coupler with a small sticker with a hand written J on it. The leads then go from the coupler to the Pots & Battery clip. The only bare wires coming from the circuit are a twin lead White and a single lead Black. My first question is: Should these pickups, if they are truly active, have 3 leads (like the ones in your current wiring diagrams)? The pickup covers are blank so I'm assuming they're not BassLines. My second question is: If this sounds like one of your systems, is there a wiring diagram I can get for it? Thanks Any thoughts or info anybody?
