Do people still give a crap? Even the best demo from Pete Thorn makes it sound mediocre.

I'm way happy with my clone and it doesn't sound mediocre at all.

sooner or later it will appear the schemo,
And the mojo will vanish in seconds.
The longer i look at the stompbox market , the more I would like to be a psychologist that owns a stompbox company.

Traced a Dumbloid Standard (without jazz/rock switch), and it's basically a slightly modded Clay Jones Overdrive (which is a modded Tube Screamer). So in fact, it's just YATS!

Schematic is not verified, but I think that's it. Regarding the photos posted earlier in this thread of the Dumbloid Special, I guess the jazz/rock switch is just a switched cap after R16 to ground (lp filter).
I tried 47-100nF, and that sounded promising. Have fun with your modded TS!

Thanks Eisy, I think that covers it

Note: Layout updated. I have moved things around a bit to get rid of one of the 3-row-span resistors and for better use of space around the left hand side of the board. There has been no other alterations and both versions posted are a circuit match so don't worry if you already started building the first version posted :)

It's a very Bad Monkey - needs a good spanking I think.

I'll take care of it, give me 20 minutes or so alone with it. :applause:

Looking at blown up shots, I'm wondering if the "Rock/Jazz" cap isn't actually going from E of Q2, switched to ground. The wire from the switch to ground is obvious enough, but looking at the proximity of the cap to Q2E, and R18, what do you think?

Built the Mark's layout above today, so consider it verified. It's not bad sounding OD at all. Resemblence to TS is minimal. I'd say it sounds like a mash of TS, SD-1 and Hotcake. But the price.. Seems like i'm charging way too little for my builds...

I must admit that my board looks better than the original...
