SD APB-1 EMG-HB, out of phase?!?!
I'm working on a project bass at the moment. It has an EMG-HB bridge P pickup, and Seymour Duncan APB-1 neck P pickup, both actives, with an EMG 3 band Active EQ.
The problem is, if I am full neck or full bridge on the balance control, the pickups are loud. Once i back off either extreme, the volume sort of drops noticeably, especially the bassier frequencies.
The only thing I can think is the pickups may be out of phase? I'm sure I've wired everything correctly. I've double, tripped checked. The pickups both go to the balance control. Both pickups have a power, ground, and hot leads, I'm sure I did it right.
Now, the EMG-HB set is mounted in an EMG guitar sized humbucker from the factory, so I know that is oriented correctly in the bass. However, I am wondering if the Seymour Duncan APB-1 set, specifically the one close to the neck, is incorrect? Could that screw this up?
Something else to mention, the Ducan set did come with 100k pots, the EMG's usually come with 25k pots. Could this make a difference?
