I will be making my own guitar pedal based on the Zvex Fuzz Factory (https://www.zvex.com/products/fuzz-factory). The Fuzz Factory is a fuzzbox, which is used to make a distorted, fuzzy effect to the signal from an electric guitar. The pedal provides a type of distortion by clipping the clean signal, adding various overtones and sustain.
I play guitar in my spare time and record my own music. However, I’ve never actually purchased actual guitar pedal hardware, so I thought it would be fun and practical to build my own! In addition, along the way I’ll learn what’s going on under the hood in pedals that make a “fuzzy” effect. It definitely helps that the Fuzz Factory schematic is readily available online and seems to be the perfect scope for a final project.
I found a sample schematic of the Fuzz Factory:
Another representation that’s a bit more pictorial:
According the Zvex, the manufacturer of the Fuzz Factory: “Although the five knobs are named for the parameters over which they seem to have the most control, please don’t hold me to it.”
- Volume: output level
- Gate: sets a floor for output sound
- Compression: reduces loud sounds and amplifies low sounds
- Drive: increases distortion
- Stability: changes supply voltage
The pedal is popular with rock musicians; see Plug In Baby by Muse: https://www.youtube.com/watch?v=dbB-mICjkQM.
With these as guidelines, I will construct / solder up the circuit and place it within an enclosure, just like a commercial pedal!
