Thanks for the answers. I think I just buy a new 3PDT switch.
I'm no expert, so fiddling with this is too advanced for me.
Are at work now, so can not send pictures of the actual box and switch.

The reason I would like to use this new switch is that I have 6-7 of them. Must have been ordering in my sleep back in the middle of the 90s.

"why are you replacing it?"
Used a little too much heat when i soldered it and melted a part of the switch. It newer realy recovered from that...

Hi. New here. I have to replace a stomp switch in a Son of a screamer pedal I builded many years ago. The new stompswitch have 8 lugs. Can`t find any schematics on it. The lugs are numbered in pairs: 1+1, 2+2, 3+3, 4+4. Tried a lot of configurations, but no luck. Also like to put a led on it.
