This is based on the classic Colorsound "Fuzz Box" of the 60's with a huge influence on both 60's and 70's 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. This silicon fuzz was the original design of Engineer/Guru Dick Denney. Like other Colorsound pedals it has a 70's tone even though it came to be in the 60's. 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 a 2N5089 - 2N5088 combo works very well and other Transistors can also be considered.
We recommend a socket and see approach and experiment.
For example you may wish to try 2N5089,2N5088, 2N4401, 2N3904 or 2N222.
Dimensions - 1.20" by 1.08"
While this will fit into a 1590A we recommend a 1590B.

See our Home Page for all Guides!
Check the Layout Gallery section of the Forum and find your project before building.
Troubleshoot threads must have pictures and voltages.
All builds are 100% verified. Be sure to use Genuine Transistors and IC's
Any serious builder should have an Audio Probe to diagnose problems quickly.
