I bought a S Duncan basslines "vintage" pickup for my mexi P bass. Its seems the wiring diagram provided by S Duncan is different then the wiring in my P bass and Gearhead website. A few different soldering points and the capacitor on the Duncan layout is .022, while the capacitor on the Fender layout is .050 and soldered to a different pot tab than the duncan layout. Which is correct or preferred? Is there a sound difference between the 2 wiring layouts and capacitor values? Should I just wire in the 2 pickup leads like the originals or tear apart the whole wiring and re-wire to Duncan specs? I'm alittle confused.. thanks!
