Frequently Asked Questions - Graphic Fuzz Electro Harmonix

How do I power the Graphic Fuzz?

Use a standard 9V DC power supply with center-negative polarity, or a 9V battery. Connect the power supply to the DC jack on the pedal.

Can I use the Graphic Fuzz with bass?

Yes, the Graphic Fuzz works well with both guitar and bass, thanks to its graphic EQ that allows shaping the low frequencies.

How do I set the EQ sliders?

The six sliders control frequency bands: 100Hz to 3.2kHz. Boost or cut each band to shape your tone. Experiment with different settings for varied fuzz sounds.

Does the pedal have true bypass?

Yes, the Graphic Fuzz features true bypass, ensuring your clean signal remains unaffected when the effect is off.

Why is there noise when engaged?

Some noise is normal with high fuzz settings. Use the EQ to cut extreme frequencies. Ensure a clean power source and quality cables to minimize hum.

How do I replace the battery?

Remove the bottom plate screws, slide off the plate, and replace the 9V battery. Close the plate and tighten screws.

Can I daisy-chain this pedal with others?

Yes, as long as the total current draw does not exceed your power supply's capacity. The Graphic Fuzz draws about 20mA.

What type of fuzz is this?

It is a graphic EQ fuzz that combines a fuzz circuit with a 6-band equalizer for precise tone control, offering a wide range of sounds from subtle dirt to aggressive fuzz.

How do I clean the pedal?

Use a dry, soft cloth to wipe the exterior. Avoid using any liquids or cleaners as they may damage the electronics.

Where can I find the user manual?

The manual is available for free download at notice-facile.com or the Electro Harmonix website in PDF format.

USER MANUAL Graphic Fuzz Electro Harmonix

The GRAPHIC FUZZ 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 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.

To operate, plug the unit into a standard AC outlet. Plug your guitar into the INPUT jack. Plug your amplifier into the OUTPUT jack.

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 small ON-FUZZ-OFF switch at the top of the unit makes the GRAPHIC FUZZ 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 already mentioned.

The VOLUME slider controls the output volume level.

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 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.
