There are no direct replacement switches for the Green Muff so I had to make a small plate to hold the new 3PDT switch. Obviously I wired it true-bypass. It didn’t have a power jack installed at all. It was being powered through a long cable coming out of the battery door. I had an 1/8″ power jack I took from an old pedal so I offered to install it for free.

Before any repairs/modifications.

Here’s how it looked when done.
