Greetings,

I have a Version 7, Third Edition Sovtek Big Muff Pi from the early 90’s. I had it in storage for about 10 years. Unfortunately it was in a hot attic for 5 or 6 months out of each year. I just recently liberated it from the attic and found that it seems to be dead. I replaced the battery of course and clicked the switch a bunch to no avail. There is no led action at all.

Does anyone have any advice for me on how to best troubleshoot this thing.

I hear it has become quite valuable and I don’t want to break it worse trying to fix it.

Thanks in advance.

Bob
