Great learning opportunity
For a DIYer like me, these files have quickly become a go to resource for PCB design. They’re filled with great ideas, I highly recommend them for anyone wanting to take their own boards into professional territory. Also, the schematics are full of their own great ideas and tweaks on classic designs.
Amazing Cornucopia of Knowledge
Whether or not you want to use these files to build VFE pedals on your own, the information contained within these files is extremely vast and eye-opening to how guitar effects work. If you have a basic understanding of how circuits work and can follow a schematic (beware, the schematic files are a little messy to quickly scan over), you should not pass up these files. Stellar work!
