Hey guys, I need some help here. I have bought a P6 and a 45DC-X for my custom bass my father and I are building, but they seem to not work together? I wire each one through separate volume and tone knobs (which work fine), but as soon as I plug both into the buss provided, the output does not work. When I route just one pickup to the output (basically volume > tone > jack), they both work. Yes, every black and white cable is where it should be, there is no hum. Yes, everything is powered because the pickups work independently just fine. Please help guys, this is torturous.
