Hello, I got a hiqh frequency noise when I plug in my bass.
The bass has single coils which I know can be a tad noisy, but most all noise stops when I touch the input jack!
Touching the strings or bridge does nothing to reduce noise, nor does it introduce noise when I have it gone by touching the input jack.
Also, the bass has a metal plate covering the unshielded electronics cavity at the back of the bass. When I touch this plate the noise doubles! I am thinking about switching out this metal lid with a plastic one, but..
Please help
