Hello, new here. Not sure if this is a repair/help forum but I do need some help.
My Peavey KB60 amp has 4 inputs: 2 highs and 2 lows.
The lows work great but when I plug into the highs I get feedback and squealing.
Opened it up and inspected the inputs, solder seemed good and didn't see anything out of the ordinary.
Odds are that both highs wouldn't be broken so I'm wondering if it may
have something to the board. Any suggestions? Thanks.
