Today I downloaded the owners manual and I like Peavey's sense of humor. It has a picture of the amps control panel followed by a description of what each item/knob does.
The input jack's explanation: "If you are having trouble figuring out what this is then please put the amp back in the box and get some drumsticks.*"
-at the bottom of page- "*No drummers were harmed in the making of this manual"
