One bias knob to rule them all!

The new Earthquaker Devices Erupter Fuzz pedal is a stripped down, no frills fuzz box that does one thing, and does it oh-so-well.  You've heard the rumors: Earthquaker Devices has spent the last two years concocting the absolute perfect fuzz tone, and it was well worth the wait.

Make your rig go vesuvius with a rip-roarin' fuzz so molten hot it'll give you sunburn.  Only from Earthquaker Devices! 

The Erupter’s simple control set stands in stark relief of its rigorous design process. A single control labeled “Bias” adjusts the amount of voltage fed to the NOS silicon transistors. 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. The Erupter uses a fixed 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.”
