    Hi! I’ve loved EHX pedals since I started playing about 5 years ago, and I’ve always loved big muffs. I started with a little big muff, moved to a modern big box reissue, and now I’ve bought a 94ish tall font big muff, but the non bypass is REALLY bugging me. I decided to change it myself with the 3dpt switch, AND EVERY RESOURCE ON THIS THING DOESN’T MATCH UP WITH MY PCB OR ISNT COMPLETE OR THE LINK EXPIRED BECAUSE ITS 20 YEARS OLD. I can’t afford to get it done by a professional but I’m damn near decent with a soldering iron and I’ve been fixing basic electronics all my life. So if I can get even a half decent photo of the mod done to someone else’s circuit I’ll be perfectly fine. Any help is appreciated!!!

    Since you say it doesn’t match up with any resources you’ve found, you should post some pics of what you have and we can go from there. It’s not terribly difficult and you can use the original switch if you can sacrifice the LED.

    Here you go, the original diagrams I drew up not quite 20 years ago. 😉

    The Russian switch has a different switching system to US, Japanese and every other countries switches.

    Follow these and you will be set.



    If you want to use the original switch and have an LED and have it true bypass then you’ll need to make and include this. However, you will still have to wire it for a Russian switch as above, not exactly as this shows.
