The all-analog EarthQuaker Devices Erupter could be the ultimate classic fuzz. Yet surprising enough, this pedal is no clone. It's the result of more than two years of tone chasing. This pedal succeeds in bringing iconic, classic fuzz tone to today's instruments — single coils to humbuckers — and to any position on a pedalboard. The Erupter's low end is defined, its top end is smooth, and its output is just right for sending an overdriven tube amp over the edge. A feature we particularly like is the EarthQuaker Erupter's foot-friendly single knob, which controls bias, fuzz, and harmonic character all at once to prevent settings overload from getting in the way of your music.
