I am hoping someone can help me .
I have 2 big muffs that seam to have the same problem.
All of these are reissues
I bought a green Russian and an op amp big muff.
I had them both on my board trying to settle on just one..
Then the green Russian started acting up.
No output at all when off. Then if I turned it on once every thing worked fine.
But worked intermittently.
Opened the pedal up no loose wires.
Reheated solder joints on switch no luck.
So I just started using the op amp.
Then the same thing starts happening.
Maybe a month later .
No sound when I have pedal off.
Now the pedal sounds terrible when it does work.
Also pedal seems to engage when I press halfway down on switch.
Pulled that off my board and put on my bass big muff and it works fine .
Same cables same power supply.
What is going on?
