The Oz fuzz gets its sweet mojo from two Vintage Silicon transistors and N.O.S parts. It has a sweet amount of gain if needed, but can also sound like a clean fuzzy boost pedal. You can get a really nice clean tone by rolling off your guitar volume and still keep the heart of your tone.
The rare guy is very lightly used and works great. Grab a piece of pedal history. It will ship out the next day.
