i have an old version of the amp and I dont know if my problem is just distortion or how im plugging everything in. I have the boss xl20 loop station and when i loop riffs to play on it is jumbled and just sounds like a mess when i play on it. Does anyone have any suggestions as to what volume level the station and amps should be on ect. Also the amp has multiple inputs and outputs on the back and i dont really know how to use them and which one is really for which =/
A looper in the wrong place can cause all kinds of havoc.

Does your amp sound OK without the pedal?

Can you turn the regen or repeats down on looper?

New battary?

Can you take a pic or explain really well what all the interfaces have in them now?
