Earthquaker Devices Erupter Perfect Fuzz
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.
EarthQuaker used every trick in the book to craft a classic fuzz Device that sounds good with any pickup type, anywhere in the chain (even before a wah pedal!) without any tone-sucking impedance mismatching. They build each Erupter with 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, and low-gain, hand-matched NOS silicon transistors to deliver a well-rounded and defined fuzz tone with just enough pummelling intensity, so you can rock n’ roll all night and still get to bed at a reasonable hour.
The Erupter’s simple control set stands in stark relief of its rigorous design process. Adding controls, removing controls, measuring resistors, swapping transistors, trying different capacitor values, rolling dice, throwing darts at transformer spec sheets on the wall… Heck, EarthQuaker would have done William Burroughs-style circuit board cut-ups if they thought it would’ve worked. If it’s good enough for the Stones, it’s got to be good enough for us, right?
What they finally landed on is a super-simple single knob setup that allows you to bias the Erupter’s NOS silicon transistors for the perfect sound and feel, while still being touch responsive and cleaning up nicely when you roll back the guitar’s volume and tone controls.
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 custom centre-detent pot is 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.
Each and every Erupter is built by the hands of real-life dream warriors in the foothills of Mt. Akron, Ohio.
