From the vendor

Our One Knob Fuzz is based on the classic Colorsound “Fuzz Box” of the 60’s with a few modern enhancements including A/B pads for additional Mods if you desire.

Description

Our One Knob Fuzz is based on the classic Colorsound “Fuzz Box” of the 60’s with a huge influence on both 70’s and Doom style Fuzz tones. Unique to our version is a tweaked resistor to stabilize any Fuzz issues as well as the addition of A/B pads at the output for further modification if you so desire. Finally each board contains Pads for the direct mounting of a potentiometer directly on the board for an easy build. Those who know the history or have played one before know that while it may have been a One-Trick pony it sure was a Sonic Eargasm of Fuzz Tone.

History: A One-Knob Fuzz is made to simply sound good. The Colorsound Fuzz Box was surprisingly versatile, using your guitar’s controls. Its great chunky rhythm tone was the original design of Engineer/Guru Dick Denney. Not so much for soloing this circuit is a monster for all out chord moshing. Sometimes all you need is One Knob to get it right.

Note the transistor type is TO-18. TO-5 sockets will not work with this project.
