EarthQuaker Devices Erupter

Can we ask you a serious question? When’s the last time you turned up your favorite fuzz pedal to anything but eleven? If there’s one true thing about rock n’ roll, it’s that it sounds best cranked all the way up. But where do we go from here? We go one louder. Enter the Erupter. 

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’.

CONTROLS

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.

SPECIFICATIONS

Dimensions: 4.75 x 2.50 x 2.25 in. (121 x 64 x 57 mm) with knobs
Current Draw: 9 mA
Input Impedance: 500 kΩ
Output Impedance: <1 kΩ

Switching
This device is true bypass and uses electronic relay-based switching. Audio will not pass without power.

Power 
This device can be powered by a 9v battery or a standard 9-volt DC power supply with a 2.1mm negative center barrel. We always recommend pedal-specific, transformer-isolated wall-wart power supplies or multiple isolated-output supplies. Pedals will make extra noise if there is ripple or unclean power. Switching-type power supplies, daisy chains and non-pedal specific power supplies do not filter dirty power as well and let through unwanted noise. DO NOT RUN AT HIGHER VOLTAGES!
