The Graphic Fuzz EQ/Distortion/Sustainer Pedal from Electro-Harmonix is an AC operated unit which features a six bands graphic equalizer. It has been specially designed for low noise / low hum operation. An LED indicator shows when the effect is in either the On or Bypass modes. This unit is sensitive to the dynamics of your playing, that is, the effect will be louder when you play harder and will be quieter when you strum or pick more softly.
The Graphic Fuzz has ten sliders. The Graphic EQ section has six slide pots which allow you to adjust the output level by as much as plus or minus 15 dB in the 125 Hz, 250 Hz, 500 Hz, 1000 Hz, 2000 Hz, and 4000 Hz frequency bands. The Volume slider controls the output volume level. The Dynamics slider controls the sensitivity of the unit to your playing style. The Sustain slider controls how long a note is sustained. The Overdrive slider allows you to control the amount of distortion in the output signal.
