This fuzz was brought to my attention by Tabbycat.
The demo sounds great, so I threw together this layout in 10 min. :)
It's not verified yet, and it will take some time before I can build it myself.

I changed the position of the Stoner switch to suit the vero. But it still does the same thing.

Cheers

Oh, that was fast! Thanks for the layout. I'llgive this one a go this evening.

[Freppo]

Great :) Let us know how it goes!

[tabbycat]

many thanks for the vero layout freppo.

[anders]

I had no luck with this one...I won't have time for troubleshooting for a couple of days now. Anyone else wan't to crack this one?

[Alex]

Did a 15 x 9 layout (cause I have many 9 strips boards to use) and it works.
I've also checked Freppo's layout and it's correct.
Did you add the cut under 22n?

[anders]

Doh! Did a cut under 22nF and layout works! Sounds amazing!

[Freppo]

Glad you got it working!

Thanks Alex for checking my layout!

Although.. when I looked it through again now, it seems like collector of Q1 is supposed to connect to base of Q2, so there actually shouldn't be a cut under the 22nF?..

[anders]

 indeed...

[Alex]

Ops! Sorry! Of course you are right.
Yesterday I've only double checked the top part of your layout (not the cuts') after I did mine and I must have checked them both before replying to Anders
I've built mine following the schematic and it works (same as yours without the cut).

[Synsound]

???
I built as per above layout and nothing. I jumped the cut under the 22n and I get the fuzz. The gain switch works but the stoner switch didn't change anything.
So for me I guess it's the No Cut version?
I may go over the schematic but the fuzz I did get wasn't real a keeper. I'm just dying for things to build.

[Alex]

No cut.
Didn't have much time to play with it.
Mine worked but I don't think it sounded anything special.
