EarthQuaker Erupter Fuzz (used)

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 (but not too mushy), a biting top end without being too harsh, and just enough output to politely send a tube amp over the top.

Low Bias settings yield a rude, spongy fuzz tone with plenty of sag and a blossoming attack envelope that's gated without entering dying battery territory. As the Bias control is increased, additional harmonics stack atop the input signal, producing a stiffer, more complex fuzz tone with a tighter response, increased output, and longer sustain. EarthQuaker had a custom center-detent pot made to fit the required resistance for the Erupter. When the Bias control is set at noon you will feel a little click. That means the pedal is perfectly biased to give the best possible fuzz tone.

The Erupter uses a fixed master output level and gain setting for the thickest fuzz possible and to push the full frequency range of the guitar out front when you kick it on.
