EHX Double Muff PCB?

[felx325]

Hi I love this pedal and I am having a hard time finding any information... is it just two american muffs in a chain with a switch? because I use the russian muff normally and I don't think it would sound pretty in a chain...

If any one has information on the schematic or pcb please help

Two of these in a row, with a switch in the middle.

I JUST built one using that Tagboard layout.



  It's almost 2 muff fuzzes in a row.  On the double, the 1st stage has a slightly different front end.

Each stage is a fuzz with silicon clipping diodes.  It's a pretty smooth sound, not abrasive and has  a lot of sustain.  When you look at the schematic, you'll see it's nothing like the Russian Muff
