This is the second “one-off” prototype velcro fuzz units on which we based the design for our new range of two knob velcro fuzz boxes.

This circuit is similar to the classic 60s Orpheum fuzz circuit. Most of the original values were changed and and the circuit topography is slightly different. This version utilizes silicon BC108 metal can transistors with negative feedback elements added to the circuit to soften the harsh silicon tone. The result is a warm sounding velcro style fuzz that retains plenty of low end and responds well to the instrument’s volume control.

At first I thought these velcro fuzz circuits would be a bit of a one trick pony, because I prefer a fuzz that cleans up when the guitar volume is rolled back. These one don’t really do that. Instead, lowering the volume of the guitar reduces the intensity of the metallic square wave tones and a more classic low end 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.

These units 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.

For this black on grey version the graphic was laser engraved directly onto the metal. The units pair of BC108 silicon transistors inside resulting in more high gain than the germanium version.
