Three PCBs and some very neat wiring. This is one of the boutique brands that brings a good name to the industry, in my opinion.

Another TGP find. :)

He does a lot of cool stuff with PT2399s and Belton Bricks, too. :)
Testing, testing, won too fwee

Seems to just be in series: right to left, like on some video demos I've seen.
The octave part is an exact Green Ringer, though this is the first I've seen with a toggle to disable the octave. The new ones don't have that. When I clone this, I'll add an order switch or extra jacks to be able to use the Ringer after the Muff half, not just the Tone Bender's.
There's also a "Cloven" version where the Hoof circuit is changed to all silicon transistors, along with minor clipping differences.

yeah i first thought that that might be the order but i'm starting to think the octave is first (by looking at the gut shot) and i read in a review that it seems to go octave, reaper, hoof, so i think i'm just going to build the three PCBs and then run them in series in different variations to see what i like best.

i read this on a review site, but it still isn't all that clear.

" The effects are run in serial (Hoof, Octave, Fuzz), and each can be activated via an independent footswitch. This creates interesting sonic opportunities for pedal stacking and allows you to play each circuit’s strengths and unique characteristics against and with each other. While the Octave on its own it creates a clean, reedy effect I love, but turning on the Reaper sends it screaming into overdrive as it wrangles in the complex harmonics of the fuzz. Turning the Reaper off and the Hoof on with the Octave feeds the Hoof the octave signal, thickening it and compressing it to a focused sustain. The Hoof and Reaper together sound better than any two high-gain fuzzes should, with a remarkable amount of clarity and definition present despite the wall of sound fuzz it creates."

Yes, I read now in the manual "The wired series in the device is Octave>Tone Reaper>Hoof."

Beautiful! 2n1306 for all 3 germanium transistors?
