I have a classic player special Jaguar (two single coils), I believe the wiring is the same or very similar to a standard Jaguar - 1 meg pots, rhythm & lead circuits, on/off switches, hi-pass/strangle switch, etc. I recently changed the wiring in my Les Paul & Tele to the 50s / Fezz Parka wiring so that when I roll back the volume I don't darken the tone too much, it works great. I tried this on my Jaguar but it didn't have the same effect. - Factory wiring: brightness and volume roll off very quickly, majority of change happens between 10 & 8, that classic Jaguar brightness is lost immediately upon volume adjustment. - 50s wiring (jumper wire moved from outer to middle volume lug): brightness rolls off more slowly, but the volume taper is quite different. It doesn't really decrease volume until about 3 or 2. As the volume is rolled down from 10 to 3 the tone changes, less like a volume adjustment and more like a tone adjustment. Mind you this is with the tone pot on 10. Might this be attributed to the 1 meg pots, which may have a different taper than my other guitars? Or the mystery resistor on the tone pot? I can live with the factory wiring but curious if anyone has insight or suggestions. Thanks!
