Hi, so I think I broke my nano big muff, and I’m not quite sure how to fix it. I kept running into this problem, where when I stepped down on the switch, the pedal would start, then fade out. I read on line that I should take the pedal apart, then clean out the switch. So I did that, but I struggled to get the little metal arms off of the switch, and in the process I accidentally ripped the light grey rubber thing that connects it to the rest of the pedal. Does anyone know how I should fix this? Any help would be greatly appreciated.

-Thanks
