Troubleshooting the onboard premap's tone knob?
Hi i'm experiencing a problem on my onboard preamp.
Its has active/passive switch, 3 tone knobs, and balance and volume.
My pet peed on the preamp, after that happened, when I turn on the bass tone knob on, the volume gets louder as well.
I don't see anything wrong other than that.
Any Idea What has happened to my gear, and know how to fix?
