The RollFuzz is a One 2N5088 transistor simple fuzz project with only one pot control (Level) that let you adjust the final effect volume. Fuzz is controled by "rolling" back the volume knob on the guitar.

An extra pad has been added on the layout to let you experiment with other transistors, just make sure to respect the pinout.

D1 can be swaped with other kind of diode(s) for a different clipping. Led, internal FET diode, bridge rectifier, 1N4001, zener, germanium or one of those little no name diodes you kept in a bag, any diode will fit here You can also mix together several diodes, seried or in parrallel ...



Soundtracks:

Clip 1 (785 Kb) - MP3 : Bridge pickup.

Clip 2 (1,24 Mb) - MP3 : D Tuned

Clip 3 (592 Kb) - MP3 : Neck pickup

All Recordings: Guitar (strat) -> RollFuzz -> Beltone AP-A tube amp (clean at low volume, 8 inches speaker) -> SM57 shure mic -> mixer (Flat EQ) -> soundcard -> software.

Nice

Hey this fuzz circuit seems very simple. I will make a try, maybe it's time for me to build a breadoard

It is really a GREAT sounding fuzz !! The sound is nice and smooth for a silicon fuzz

I learned a lot by tweaking on this simple circuit, it's a great one to start with, and I can say that it sounds very good, considering its simplicity and the little amount of parts required, thanks again maz
