Hi guys, yesterday i install the seymour duncan hot stack in my aerodyne bass. However, i didn't get to enjoy it because i think my wiring is wrong. I have two questions and i hope you guys can help me. My bass is a PJ, i am only changing the bridge pickup for now and the neck pickup is stock fender's. Situation 1 I am really confused by Seymour Duncan schmatics. The schmatics they have on the website told me to wire the "white wire" to the volume pot and the "black wire to ground". However, the schmatic they gave me (the yellow piece of paper found in the box" told me to wire the "black wire" to the volume pot and the "green wire" to ground. There five wires connected to my pickups. the black, red, green, white and one bare metal wire. So many?! Which one to use. QNS 1: Which schmatics should i follow? Situation 2 So I thought I try both. Both wiring works and i can hear my bass through the amp. But here's the problem, when i try using two pickups together, the output fall drastically. Both wiring gave me the same problem. When i rolled off my bridge pickup, the Pbass pickup out put increased back to the normal. QNS 2: How did this happen and how to solve it? This is my first time installing pickups and I hope you guys can help me. I really don't want to spend $25 to install one pickup.
