Here is a link to the DAM thread.

There are some good pics of both trace and comp side of a unit.

I think the newer version moves a trimpot to the front panel.

The one on the DAM forum is mine.
I sent it off to Jerms and he made a pretty solid clone (with the trimpot for the gate on the outside of the pedal).
I'm sure he would post his schematic if I asked for it.
here's a video comparing the two:

it actually sounds way better than this in real life; also fast forward to about 2:25 for some cool gating action.

Sounds great, edkoppel! Thanks for the info. I would love to see the schematic if you can get hold of it. Not to clone but just to add to the fuzz collection!

sorry, a little late...
but here is the schematic of my Fuzz-Stainer, traced by Jerms:

Does the 9v come in at the junction of the 100K and 4.7K?
What transistors are used?

not sure about the first question, but the transistors where 2N 5172.
here is the blog post I did on it, with a ton of pics.

and with axial 100uF if someone prefer those

Can You add another one with external bias, like in Jerms replica?
It seems to be really usefull.

Never seen Jerms replica... You mean pot in place of trimmer?

Yup! Here's gut shot of Jerms replica.

here you go, I like it better that way, I hate to place trimmers

beedotman · Post by **beedotman** » 13 Apr 2012, 08:36

Now it looks beautiful!

One correction should be made - cap on Q1 emmiter, in left down corner of vero should be 1nF instead 10nF according to Jerms schematic.
