The Knob of Doom is a dead simple fuzz and distortion machine. Unlike many classic fuzz circuits that get lost in a band mix, the Knob of Doom is designed to cut through and be heard.
Don't be fooled by the single volume control. The secret to the versatility of the Knob of Doom lies with your guitar's volume and tone controls. Changes in pick attack and your guitar's volume allow everything from sparkling clean to sagging aggressive fuzz.
