Hello,

I plugged in a Danelectro Cool Cat Chorus and got a hum in the amp. I think I plugged the cables in correctly, IN from guitar and OUT to amp. Got a loud hum. Reversed the cables. (I know, so don't say it....) still a hum. However, there is now low volume output with direct plug in and on both inputs. And the amp was fine yesterday. I must have damaged something, but no idea what.

Need Help.
