By the way, if you have a single coil passive jazz bass and like your stock electronics but would rather go active then you might look into the EMG J-set pickups. They come with a active electronics harness but the electronics do not have an eq on it per-say. It has two volumes and a tone roll-off much like a stock passive preamp. I'm installing one into my 1975 Jazz bass and I'm excited about how its going to sound. I had the Audere in there but took it out and I'm going to replace it with the EMG's. Two of my favorite bass players (Alex Al & Maurice Fitzgerald) use them in their jazz basses, and I also have a cousin who has a 72 jazz bass that has EMG's in them that he bought back in 1989 and that bass sounds killer. You just have to use the eq on your bass head.....very simple and not a bunch of fumbling around on your bass to get your sound. Want highs?? Just use the tone control!!! No highs?? Use the tone control....that simple. I was skeptical of EMG's I've always been a fan of Barts because of their clear pristine sound.......but I like to be felt and heard when I play and I believe that the EMG's will do that for me.
