After seeing a request for an unreleased DOD / Devi Ever collaboration pedal and looking into it I decided to go ahead and use it as a learning exercise to move off of EasyEDA and into KiCAD for my PCB designs. Plus, I'm a huge fan of fuzz pedals, so it made a lot of sense in my mind. The general layout of the unreleased circuit is a Hyperion into a Big Muff style tone stack with a boost tacked on at the end. As someone who can never leave well enough alone, I added a few things: a tone bypass, an on/off/on switch to change the fuzz circuit between three Devi Ever fuzzes (Hyperion, Ruiner, Bass Ruiner) and a feedback potentiometer in case any of the three fuzz modes wasn't nasty enough for you you've now got the ability to make it sound even better (worse?) if you'd like.

On the faceplate I decided to be Spaceman-esque with a dash of Sheepylove and the see-through light up logo. When turned on, you get a light up succubus, cause well, why not?

As far as the PCBs and such, I had a few rookie mistakes: mislabeling the oscillation value to 100kA instead of 10kA (100kA is usable just 10kA is easier to dial in) and on the faceplate, I didn't recheck my spacing for the switches, so it didn't line up as easily as I would have liked. Both have been corrected in the files below

If a weird mashup of Devi Ever, Big Muff tone stacks, and make up boosts seems like fun to you and you want the gerbers for the PCB and faceplate you can get them here (where I also created a Tayda Drill Template too) or I've got some PCBs as well from my first run (the oscillation pot is still labeled at 100kA).

On the actual build, I chose the purple fury 125B from Stomp Box Parts along with their anodized purple knobs for that high class look. I used a white LED mounted directly against the board to get a nice fill of the logo.

Super cool! I used to sell this exact configuration, and a sm/vfm with the same features (switchable big muff tone stack with post boost) and a voltage starve.
I'm a huge fan of voltage starve on fuzz circuits; I just ran out of room on this one. I guess that means I'll have a second revision at some point. :)
