Hey,

I got my metal muff this past Christmas and today its stopped working. The device will power on, but the guitar signal doesn’t pass through when engaged. When it’s turned off, the signal passes through fine. I took the internal battery out (i use a 1spot) not really thinking it had anything to do with it but was willing to try anything. This is my main distortion, so i’m kinda out of commission until this is fixed. I also checked the connections, cables, etc. Its probably an easy fix, I’m just not sure what to do.
