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

$5.95 $6.95

Back 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.

Always use the Forum's Layout Gallery Page for each individual circuit for the most information, mods and tips, that are not contained in the basic build document above.

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.
