One Knob Fuzz - Colorsound Style Fuzz - Back by Popular Demand


By Popular Demand

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 designed by Bruce R. 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. In the style of GuitarPCB in an effort to add options or enhancements  A / B pads are included at the output for mods that will be listed in the Layout Gallery.

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 rythymn 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.

A must have Fuzz Circuit for an Fuzz Fan's collection!

While the original calls for a combination of BC108 and BC109, we have found that 2N5088's also work very well and other Transistors can be considered.

We recommend a socket and see approach if you wish to experiment.

For example you may wish to try 2N5089, 2N4401, 2N3904 or 2N222.

Dimensions - 1.20" by 1.08"  

While this will fit into a 1590A  we recomend a 1590BB.
