I have a Fender Modern Player Jazz (V string) that I really like; it has a 4 position knob which allows the player to choose from 4 different tone settings; I actually only use one of them, the other 3 are pretty much useless ... (to me anyway). I'm really considering dropping in an Audere JZ3 Pro preamp that I already have just laying around; I'm thinking it'll give me more useful tonal options; I just don't understand the wiring on the pickups, I believe there's 4 leads on each pickup but I'm not sure which is hot, ground etc.. Does/Has anyone have/had a Modern Player Jazz and dropped in an on board preamp? Was it easy/simple enough? Was it worth it. ... the photo is not my Bass, but it's this exact model, color combo and all, Thanks
