DIY project in progress. 14 knob fuzzer with a parallel loop mix/blend and a parallel path deep bass frequency fuzz plus other goodies.
The values aren't finalized. I've yet to do the final tweak but the design topography is finished. I've got a PCB designed for it, I'm just too broke to get the PCB's ordered. Hopefully I'll be able to sell some stuff when I get to 50 posts here. Obviously muff inspired but I think the clipping diode arrangement is a pretty unique idea... clips highs much harder and allows for multiple clipping knee curves at once throughout the frequency range...in terms a pretty heavy sounding buzz that morphs with sustain and decay. Throw in hard asymmetry and a bit of crossover distortion and it gets really mean.
Stay tuned and let me know what you think. The PCB is just a hair over 4 inches square and will cost about $20 a board because I use a pretty expensive service. Double sided and plated through holes with silkscreen and soldermask.
GNAR-WALL as in a wall of gnar which can only be penetrated by a magical blubbery sea creature:
first let me say this project looks great! only problem is that PCB express charges $$$ compared to itead studio or seeed studio. the software is easy but eagle is so much better. you can get that PCB made for $3 or $4 total shipped from china. you can sell it at any price you like but I really hope your not paying $18 each and selling them at $20. you deserve to get paid a lot more for your work. trust me when I say that this project is in phase 1 of research and development. after getting lots PCB's made for stuff I designed, I can tell you that all the people who test your products will give you valuable feedback. not only will the final values change, but the panel controls most likely will also. with 14 knobs and 4 switches I can pretty much say chances are high that there will be something about it you might feel like you don't need after you get to jamming on it. this is true even if you have tested this thing on breadboard. you might only notice something on someone else's amp or guitar or play style.
learn eagle or kicad. you'll thank me later when you can order this project $25 for x10 pcb.

Yeah yeah I know but the PCB design is done, so I'm getting a few made.
my chit computer won't run eagle.
