Product Overview

Total fuzz sound sculpting is once again available at the true tonal alchemist’s fingertips! The Electro-Harmonix EHX Graphic Fuzz pedal is an AC operated unit which has several unique features including graphic equalization which are not found on any other fuzz/distortion/overdrive products on the market today.

The Electro-Harmonix EHX Graphic Fuzz 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 small ON-FUZZ-OFF switch at the top of the unit makes the Graphic Fuzz pedal a dual purpose effect. In the ON position, the fuzz effect is on. In the OFF position, the fuzz is off and the unit can be used as a graphic equalizer using the six slide pots. The six slide pots allow you to adjust the output level by as much as + or – 15 dB in the 125 Hz, 250 Hz, 500 Hz, 100 Hz, 2000 Hz, and 4000 Hz frequency bands. This allows for great tonal flexibility.

The envelope shaping capabilities of the unit are controlled by two slide pots labeled DYNAMICS and SUSTAIN. The DYNAMICS slider controls the sensitivity of the unit to your playing style. When the slider is down, the unit behaves like a conventional fuzz box with the output volume at a more or less constant level. As the slider is moved up, the unit becomes increasingly more sensitive to the dynamics of your playing. It will get louder as you play harder and will get softer as you play more gently. The SUSTAIN slider is only effective when the DYNAMICS slider is up. It controls how long a note is sustained. Maximum sustain is achieved when the Sustain slider is all the way up. The VOLUME slider controls the output volume level.

The OVERDRIVE footswitch allows you to control the amount of distortion in the output signal. The CUT footswitch allows you to bypass the entire unit without having to physically disconnect it. The red LED will light up when the unit is engaged and will go off when the unit is bypassed.
