I wonder if anyone can help. I have a Faith Neptune Trembessi which has the below preamp.
The guitar has been playing up recently whereby when plugged in, the sound keeps cutting in and out. I tried various things like different cables, batteries etc but tonight I worked it out. The circled button "EQ-S" seems to be the culprit. If I slightly touch it, the sound cuts out. Pressing it in or out doesn't make a difference.
(To be honest I've never quite put my finger on what the button does) Does anyone have any idea what could be the solution to this? Could it be an easy fix or would it need taking to a luthier?
