I've just uploaded the KiCad schematics for reference. It's still a draft, no complete prototype built yet.

I've uploaded the library I'm working on to GitHub. I also added a hackaday project for this. You're welcome to contribute, still a lot to do!

First messy prototype is making sound! Codec module (see my other project, Yummy ADDA Cookie) seems to work nice, no dropouts. Sounds good but want to measure the noise level soon.

I'm currently working on the codec board, which holds all the fine pitch stuff. The PCB just arrived. See my ADDA Cookie project for more details...

I'm thinking of modularising the project. Splitting it into a small FET Preamp module, an AD/DA module and an IO-Board which holds everything. I really like the small castellated holes-style PCBs like the ESP32 module. Have to check how to do that in KICAD...
Prototype phase

This project is in a pretty early stage. I'm working on the prototype board. Lot's of design decisions are still to do. Any input or discussion is welcome.

Challenges are:
- The small form factor while having huge components like all the jacks and the stomp switch
- Signal to noise ratio must be high as guitars get highly amplified in later stages
- Should be not too hard to build
- Should be not too expensive
