Nashville 400 Buzz Issue

Post by Chase Phillips »

Hello all. I recently purchased a chrome corner NV400 and after bringing it home today from a rehearsal, I plugged it in and turned it on when it started making a constant, uncontrollable buzzing/humming noise. The buzz was not affected by either of the gain pots, or EQ pots. I also unplugged the cable from the input jack still with no avail. I’m taking it to my local tech in the morning but any suggestions as to what might be the cause would be greatly appreciated!

Likely a capacitor? First look, filter capacitor.

Along with Dennis. Probably could use new filter capacitors. That would be my first step.

Have you tried turning the reverb off? Also check the molex connector.
