Hold the presses. It is working!

Maybe I just did not have things hooked up properly before but it is working
fine and sounding great.

Thanks again for the help!

I picked up an old Electro Harmonix Muff Fuzz guitar effect box. Not to be
confused with "Big Muff" or "Double Muff" units. Seems pretty simple but
it is "big" to me in regards to figuring out how to fix it.

Here is what it is doing; Guitar signal passes through until I flip the
switch ON, then there is no sound.

Here are pictures of my unit...

I can use a VM and can solder repairs. The pot and the switch seem to be
working. Can anyone suggest what I should check next in trying to fix
this?

Much Thanks, Mark
