This is the first of our one-off prototype fuzz units on which we base the design for our range of two knob velcro fuzz boxes.

As a starting point I used the architecture of the classic 60s Orpheum fuzz circuit and applied modern components and a variety of modifications to improve the usability of the device. After hours of testing on a desk with an oscilloscope I eventually arrived at a sound that I believe gives the musician the widest range of tones possible with this circuit.

Most of the original values were changed and high frequency negative feedback networks were employed (among other techniques) to eradicate unwanted noise. The result is a bright, harsh sounding velcro style fuzz that retains plenty of low end and responds well to the instrument’s volume control.

At first I thought the velcro style fuzz would be a bit of a one trick pony, because I prefer a fuzz that cleans up when the guitar volume is rolled back. This one doesn't really do that. Instead, lowering the volume of the guitar reduces the intensity of the metallic square wave tones and a more classic rock fuzz sound is revealed.

The BLEND knob controls the mix of fuzz and “clean” signal. Although clean signal is a bit misleading in this case — it’s more a deep bass-y guitar tone, the usefulness of which does not really become apparent unless your amp is set to mild breakup. In that case you get an interesting mixed fuzz / distortion tone.

This unit has plenty of bass and would be just as at home on a pedalboard aimed at DOOM metal as it would be in a 60s style psychedelic rock setup.

This one-off prototype device has Germanium transistors, and is a chance for you to own a piece of Volume & Power development history. The enclosure is from the experimental artwork phase, featuring laser-engraved paint and embossed labels for a road-worn, punk look.
