Bellows®
Fuzz Driver

Greetings, dungeon masters! Stoke the fires in the seventh circle of tone with the Bellows! This little two-knobber is a nod to the non-master volume amps of yesteryear and the fiery tones that come only from diming these vintage behemoths and letting 'er rip until the tubes catch fire. For your safety, and the safety of others, the Bellows packs these tones into a compact Dirt Device without any of the pyrotechnics.

The Bellows isn’t based on anything in particular, but it straddles the line between amp-like grit and fuzzy saturation, with a bunch of useful distorted places in between, capturing nearly every era of Rock-and-Roll in a box. If I were you (and it’s a good thing I’m not) I’d resist the usual urge to dime it right away, as the Bellows’ character changes dramatically based on where the “Drive” is set.

Our simple, scorched-earth approach to design leaves the full frequency response of your instrument intact, which makes the Bellows a great bass overdrive, and guarantees that what goes into the Bellows is what comes out, only hotter. On lower "Drive" settings, you'll find responsive and dynamic amp-like breakup. Dime it, and you'll hear full-on thermonuclear saturation. Just remember, where there's smoke, there's fire.

1. Level: Adjusts the output level by setting the bias voltage of the transistor. A small amount of noise while dialing this in is perfectly normal.

2. Drive: Controls the input gain of the device for different levels of dirt. You’ll find that it is thinner and more clean counterclockwise and thicker with more growl clockwise.

Dimensions: 4.75 x 2.50 x 2.25 in. (121 x 64 x 57 mm) with knobs

Output Impedance: <1 kΩ

Switching

This device is true bypass and uses electronic relay-based switching. Audio will not pass without power.

Power

This device can be powered by a 9v battery or a standard 9-volt DC power supply with a 2.1mm negative center barrel. We always recommend pedal-specific, transformer-isolated wall-wart power supplies or multiple isolated-output supplies. Pedals will make extra noise if there is ripple or unclean power. Switching-type power supplies, daisy chains and non-pedal specific power supplies do not filter dirty power as well and let through unwanted noise. DO NOT RUN AT HIGHER VOLTAGES!
