GuitarPCB Fuzzstortion Manual

Advertisement

With 80+ unique circuits under our belt we are getting picky about what we release.
This time it is the Fuzzstortion, not because it is less filling but because it sounds great!
This Guitar Volume sensitive circuit achieves tube amp style breakup to Fuzzy Saturation.
In between you'll find an array of useful overdrive and distortion tones to play with.
The Fuzzstortion will also handle bass frequencies extremely well.
No need for a tone control as it delivers the full frequency provided by your rig. ​

Build Notes:​ You may use 9mm potentiometers as an on-board pot if you wish. Simply solder them to
the back side of the board and align the lug number with the silkscreen on the board.
Use Sockets for the transistors so you may try different ones and prevent overheating the transistor.
This board comes with dual power and ground pads which are convenient for combo builds.
