Dead Astronaut Space Patrol Fuzz

[Charan]

Hi, I heard a demo of the Dead Astronaut Space Patrol Fuzz, which I believe is a heavily modded Big Muff circuit. He does not have the PCBs for sale on the website and he posted the schematic and perf layout on DIYstompboxes:

It looks like a surprisingly simple circuit for something so versatile.

I was wondering if anyone has done this on veroboard. Thanks!

Hey there,
here's my attempt for a vero - but be sure to check it against the schematic before giving it a try!
Did not find info on the diodes 1-4 though.

As always I ended up with a link running cross-board finally

EDIT: Layout updated (Input added)

Found an entry by deadastronaut himself stating either 5088 or 3904 work nicely for Q's and diodes should be 4148 or BAT85
here's the post: LINK

Man that sounds badass in the demo. Didn't realize DA is such a shredder! Might have to try this one out.

[Charan]

WOW! That's great, thanks for doing it. It will take me a while to get this together, but
I'll post when I do it.

Were does the input go?

[Travis]

Looks like it will go to A-E (the bottom leg of the 33K on the left toward the top)

[Hozy31]

Thanks Travis. I sort of expected it to go there due to the 1M pulldown resistor.

Ouch, sorry guys  I'll fix the layout as soon as i'm back at - well, where the computer is

Great layout Mug!
Done one last year for the main page but then forgot about it (have a few of those)!
It came out a bit smaller (21x15).

[Hozy31]

Would love to see your version Alex, now you've mentioned it .

[mug]

Thanks Travis - and I'd be interested to see your layout too - curious how you managed to get it smaller (experience I guess )
If you don't mind would you post/send it?

[Alex]

Just more practice and luck, I guess.
I'll add it to the main page.

Thank you Alex - interesting to see how you did the layout. I especially like the arrangement of pot connections, its so much neater to wire the pots when they're grouped

Any reason these two 100K resistors (R21 + R13) cant be replaced with a single 200K??
