Russian Big Muff True Bypass Help

[alteredsounds]

Hi!

I picked-up a Russian (black Big Muff) for £10 yesterday that sounds suprisingly good.  I'd like to make it True-Bypass and have done so for a few other pedals but on this one, all 3 pots have their center lug connected to the exisiting switch and I dont really know where to move them if I put in a 3pdt switch?

Found lots of diagrams to do this to the green russian Big Muff but the black one seem alot different.

Sorry if this seems a bit dim!

Cheers,
Nick,

anyone know where these 3 center lugs from the pots go?

The center lug of all 3 goes to the switch? Hmm. That certainly does not ring any bells - I've never seen the insides of that one, nor a schem - not looking anything like that! Sound rather strange. Could you make a few pics perhaps - that might clarify things.
With any weird switching setup you can always figure out what the "on" connections are (perhaps muck with the electronic switching if it's there) and hardwire it to always be on. Then adding a DPDT is a breeze, if there's sufficient space. Add a Mil2 and Bob's yer uncle for a LED. Or just stick in a 3PDT.

This sounds very weird to me. Pics would help!
