I am having an issue with feedback on the clean channel.
At medium to high volume I am getting a weird feedback problem on the clean channel.
I can cause the feedback to start by tapping on the cabinet or the back panel of the amplifier, with an imput signal or without. It is independent of the footswtich.
When I change to the other two channels I can tap on the cabinet and hear no response in the speakers. On the clean channel you can hear each tap, sometimes building to a feedback howl.
Any suggestions?
