GRAPHIC FUZZ
-Operating Instructions-
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 wil 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.
