Hello folks, I just started building my own pick ups. They work great when hooked directly into my battery Pignose. However, once I put a 250k Audio pot between them. I get a loud hum. The hum increases when I touch the ground wire from the jack to the pot. The hum also changes when I reorient the pick up from the Pignose.
Any idea how to fix this other than leaving out the pot?
Thank you in advance.
