What This Repository Is

This is a collection of DIY guitar pedal designs you can actually build at home. A guitar pedal is a foot-operated device that changes how an electric guitar sounds — adding effects like distortion, echo, or pitch shifting. Instead of buying pre-made pedals, this repo gives you the blueprints (called schematics and PCB designs) so you can order the parts, solder them together yourself, and create a working pedal from scratch. The designs fit into a Hammond 1590A enclosure, which is a standard small metal box used by hobbyists for this exact purpose.

The author has created several different effect pedals here: a "fuzz" that distorts the signal, an "octaver" that shifts the pitch downward, and a "clean boost" that makes the signal louder. Each one is a learning project — the author openly admits they're testing circuits they don't fully understand yet and that modern guitar pedals are usually digital anyway. But that's exactly the point: building analog circuits (using transistors, diodes, and capacitors) from first principles is a great way to learn how electronics actually work.

What makes this practical for hobbyists is that the author deliberately chose components and techniques suited to hand-soldering at home. The circuit boards are designed to be manufactured cheaply by services like JLCPCB, and the components are sourced from accessible suppliers like Tayda Electronics and Amazon component kits. Everything avoids tiny, fiddly parts — the smallest components are 0805 size (about the size of a grain of rice), which is genuinely manageable without factory equipment. The designs use surface-mount components (smaller, modern parts) rather than through-hole components (the older kind with long legs), but intentionally avoid the super-tiny pitches that would require special stencils or reflow ovens.

The repo is split into a "base board" that handles the stomp switch and power, and separate effect boards that plug into it. This modular approach means you can swap different effects without redesigning the whole thing. Fair warning: the author is upfront that these circuits are experimental and the results are unpredictable. But if you're curious about how guitar effects actually work at the component level, or you just want to learn hands-on electronics by building something you can actually use, this is a solid starting point.
