The Erupter is the distillation of EarthQuaker Devices president Jamie Stillman’s unabashed love for fuzz and the culmination of over two years worth of tone-chasing, tweaking and experimentation in search of the ultimate, classic fuzz tone. Did he succeed? Heck yeah! An abundance of earthshakingly awesome and erupting fuzz tones awaits you in a pedal so easy to use, it’ll blow your mind!
As a fuzz device, Erupter sounds good with any pickup type anywhere in the effects chain without any impedance mismatching and even before a wah pedal. To this end, the Erupter uses a buffered input section, transformer-based pickup simulation, new production 5% ½ watt carbon composition resistors, metallized polyester film capacitors, Sprague and BC electrolytic capacitors, plus low-gain, hand-matched NOS silicon transistors to deliver a well-rounded and defined fuzz tone with just enough pummelling intensity.
The simplicity of the Erupter controls stands in stark relief of its rigorous design process. A single knob labelled “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.
