Weird grounding issue....Please help..

Sign in to disble this ad
Hey now,

Just finished the Millenium preamp install on my Cirrus. I had a bit of an issue with soldering early on but fixed my mistakes. (See my PCB thread) Anyways I've checked all my joints and all appear to be solid with no cold joints visible.

The problem. When I touch the mid control knob I guess this nice buzz/hum..similar to touching the end of a guitar plug when it isn't plugged in to the guitar. If I touch the knob and then anything in the grounding circuit it goes away. I rechecked my grounding joint from input jack to the board and resoldered for posterity.

Am I missing something? Could this be caused by a cold joint in my pickup ground soldering?? Any help will be much appreciated.

Blessings
Michael
