The erupter EarthQuaker Devices strikes very hard with its extreme simplicity and formidable efficiency! It is an analog fuzz pedal that focuses on a perfectly authentic sound directly intended to side with the great classics of the genre. It offers a well-defined sound on the bass and soft on the treble with an output level just high enough to push the amps to their limits! It is controlled very simply by means of a single potard named Bias which influences the harmonics and the level of fuzz injected into the signal. Also note its soft-touch switch that allows a smoother and quieter interlocking as well as the jacks on the upper part that facilitate installation on a pedalboard.
