LIBERATION FREQUENCY FUZZ
Build Document last updated april 2024
Version 1.0 2024
The Liberation Frequency Fuzz is a analog square wave fuzz with a
tunable and tracking monophonic oscillator that can be tuned from about
one octave down to one octave up and anywhere in between. It also has
a fun warp feature that uses a PLL output to create interesting sounds to
the oscillator even when it's "out of tune".
This pedal works best with high output pickups. It is a gated fuzz. If you are
using single coils and need more sustain, try a boost or compressor in front. To
improve tracking of the oscillator, use the neck pickup on your guitar and play
single notes closer to the 12
th
fret.
Have fun building and playing with the Liberation Frequency Fuzz!
Prototype build
The Liberation Frequency Fuzz is namned after the song by the band Refused
where my brother Dennis is the singer. We want the airwaves back!

- Page 3 General building tips • Just follow the Bill of Materials and solder the low profile components first. Recommended order: resistors and diodes, chip sockets, trim pot, multilayer and ceramic capacitors, film box capacitors, transistors/voltage regulators, electrolytic capacitors, pots and switches, offboard wiring (jacks). Bend the legs of the components alittle bit to prevent them from falling out, or use tape to hold them in place while soldering.

This template is approximate. • Make sure your printer isn't doing any scaling (100% print size). • Jacks are measured from the edge at the front/top of the enclosure (as they were drilled on the prototype), but you can drill the positions for the footswitch, DC jack and input/output jacks to your own preference.
