Calling all fuzz guys, looking for a build

[Screamingdeal]

Similar to the greenhouse sludgehammer. Check the review on the youtube by Ryan Bruce. Now I am not a fuzz guy, never owned one, but this pedal has changed my mind. I am a big fan of sludge bands like Down, Crowbar, Eye hate God and the like. If anyone can point me in the direction of a fuzz build that has the tone and sound similar to the sludgehammer I would appreciate it.

Is that it Leo?
Buffer >500x gain stage> SRPP and tone control.
The srpp will be noisey/fuzzy on its own.

What about removing the buffer, or placing it at the output.

i loved the sound of that pedal too. Hope someone can give the exact schematic of that circuit.

It's from a trace of an original unit at the other place:

Thanks Leo.
Theres your schematic then guys.

[Screamingdeal]

Amazing, thank you!

MUST TRY

is that schematic correct?  I don't like the "design"
If one looks close it is gain stages into something like a BMP tone control(50K and 10k loading of the tone control?)

I would adjust a muff circuit

Gus, if you look at the gutshots in the link I provided, you will be able to judge for yourself how close the schematic is to the Greenhouse sludgehammer that OP requested (I did not trace it, I assume deafbutpicky drew what he could see and guess from the pictures provided by Jooshtin). I'm also not that keen on the overdriven muamp thing, but I'm not a big fan of the BMP tonestack either.

" I'm also not that keen on the overdriven muamp thing,"

I agree with you there Leo.
I built the Shaka 5 and it was much better without the mu amp and still had loads of volume.

I agree.
The input impedance of the opamp gain stage is big enough, I don't know if the input buffer is needed.
And as Gus noted, there is some loading at the output, so the input buffer could be adapted as a recovery stage or output buffer to make the tone control independent of whatever comes next.

Found another fuzz called black goat fuzz. It's a beast too. Should be easy to modify a tone bender or a fuzz face.

Roland Bee Baa clone?

I did not look at the link. 
Maybe the first poster should test a IC BMP like circuit.

[deafbutpicky]

the red traces are assumptions as I couldn't see what's beneath the op amp on the pictures.
I'd say it's totally reasonable to put this at the end of the tonestack.
BTW I put the  tonestack buffered into my tube overdrive and really like the sounds I can get with it.
values: cap to ground 68n, parallel cap 47n, no modern, no bypass cap on tone pot, 510 ohm
series resistance to body pot.
