Thirty7 FX Fat Guy Little Coat Fuzz

The Fat Guy Little Coat Fuzz is a fuzz pedal from Thirty7 FX, a BC108/109 silicon fuzz based on the old school Colorsound Fuzz Box circuit. Pedal of the Day describes it as "giving the user a wide range of sounds, volumes and, most importantly, fuzzes"¹.

What it does

The pedal is built around a single dial. As Pedal of the Day puts it, "as you slowly turn the lone dial clockwise, everything begins to increase in intensity and excitement"¹. At the low end of its range, the reviewer found "it starts off slow and low, with both the Volume and Fuzz in the low-gain area at lower levels," with no shortage of output level¹. That makes the knob do the work of both volume and fuzz in one sweep, from a quieter, lower-gain voice up to a full fuzz.

The circuit follows the Colorsound Fuzz Box, a silicon design using BC108/109 transistors, which places it in the family of old-school silicon fuzzes rather than the germanium designs some other fuzz pedals use¹.

Design and build

The PCB design work was done by Alex from Coppersound Pedals. Pedal of the Day's reviewer wrote that "the quality absolutely shines through build quality"¹.
