Erupter

The Erupter by EarthQuaker Devices is an ultimate classic fuzz pedal designed to deliver a well-rounded and defined fuzz tone with just enough intensity. Here are the technical specifications and features:

- Controls: The Erupter features a Bias control with a center detent for the "perfect" fuzz setting. When in the center position, the tone is big and round with a slight volume boost and great sustain. Turning the control counterclockwise makes the tone more gated with lower output, while turning it clockwise makes it louder and more refined.

- Design: The Erupter is designed to provide a big low end without being too mushy, a biting top end without being too harsh, and just enough output to send a tube amp over the top. It offers excellent wide-range clean up with the guitar’s volume control without losing too much low end.

- Parts: The Erupter uses new production 5% ½ watt carbon composition resistors, metallized polyester film capacitors, Sprague and BC electrolytic capacitors, and NOS, hand-matched, low gain silicon transistors for temperature stability and predictable operation under all extremes.

- Power: The device can be powered by a 9v battery or a standard 9-volt DC power supply with a 2.1mm negative center barrel. It is recommended to use pedal-specific, transformer-isolated wall-wart power supplies or multiple isolated-output supplies to minimize noise.

- Dimensions: 4.75 x 2.50 x 2.25 inches (121 x 64 x 57 mm) with knobs

- Current Draw: 9 mA

- Input Impedance: 500 kΩ

- Output Impedance: <1 kΩ

- Switching: The Erupter is true bypass and uses electronic relay-based switching. Audio will not pass without power.

The Erupter is hand-built in the USA and comes with a lifetime guarantee.
