The Erupter is the result of over two years' worth of tone-chasing, tweaking, and experimentation in search of the ultimate classic fuzz tone with a big low end, a biting top end without being too harsh, and just enough output to politely send a tube amp over the top to deliver a well-rounded and defined fuzz tone with just enough pummeling intensity, so you can rock n' roll all night and still get to bed at a reasonable hour.
It's the perfect fuzz... just sayin'.
Bias: This control has a center detent for the “perfect” fuzz setting. When in the center position, the tone will be big and round with a slight volume boost and great sustain. As you turn this counterclockwise it becomes more gated with lower output. As you turn this clockwise it becomes louder and more refined.
