Hey all! So recently I've been playing using my Fender Acoustasonic Jr amp, and I've gotten a really weird issue where sometimes when I play it sounds like there is distortion on it.

The way I have been fixing it is by switching another amp cable, but the old one works again after that as well and after a while it will become distorted again.

Anyone know what's going on here? >.<
To replace a conversation we might of had:

Distortion you say?
Right well let me follow the signal path, right - yep, hmmm
Well this MXR fullbore distortion might be the source
Well assuming you've NOT been a complete dunce and ran your acoustic through a distortion pedal as well as assuming that you're using an acoustic guitar for an acoustic amp, it might just be that the battery is low on your acoustic.
