Electro-Harmonix FLATIRON FUZZ User manual

FLATIRON FUZZ
Congratulations on your purchase of the Flatiron Fuzz, an extremely versatile,
classic op-amp powered pedal that can take you all the way from warm, round
overdrive to full-on, fuzzy distortion. At lower drive settings the Flatiron Fuzz will
remain fairly clean adding a pleasant mild drive. At medium and higher drive
settings the Flatiron Fuzz can produce a thick classic tone circa the late ‘70s and
far beyond. The expressive filter lets you dial in just the right amount of high-
end...from dark to raunchy. The Flatiron Fuzz features true bypass.
Electro-Harmonix trivia: the Flatiron Fuzz is named after the historic Flatiron
Building in New York City. It’s an iconic landmark located just down the block
from EHX headquarters in the 1970s and it’s the building pictured on your pedal.
OPERATING INSTRUCTIONS
DRIVE Knob —Controls the amount of input gain that goes into the fuzz
circuit. Turn the DRIVE clockwise to go from clean to high gain.
FILTER Knob —Sets a low pass filter that tames the natural highs that are
accentuated by the fuzz circuit. As the FILTER knob is turned clockwise, the
filter’s frequency increases allowing more high-end to pass through the pedal.
VOL Knob —Adjusts the output volume of the Flatiron Fuzz.
FOOTSWITCH and LED —The footswitch toggles the Flatiron Fuzz between
effect and true bypass mode. The LED lights when the effect is engaged.
INPUT Jack —This 1/4” jack is the input to the Flatiron Fuzz. Plug your guitar
into here. The input impedance is 1MOhm.
AMP Jack —This 1/4” jack is the Flatiron Fuzz’s output. Connect this to the
input of your next effect or amplifier. Output impedance varies from 500 Ohms
to 25KOhms depending on the VOL Knob setting.
POWER
The Flatiron Fuzz can run off of a 9V battery or you can use an optional 9VDC AC
Adapter capable of delivering at least 25mA to the 9V power jack, such as the
EHX9.6DC-200. The AC Adapter must have a center negative plug. The battery
may be left in or taken out when using an AC Adapter. The Flatiron Fuzz has a
current draw of 5mA at 9VDC.

Please Note: Using the wrong adapter or a plug with the wrong polarity
may damage your Flatiron Fuzz and void the warranty.
Changing the Battery
To change the 9-volt battery, you must remove the 4 screws on the bottom of
the Flatiron Fuzz. Once the screws are removed, you can take off the bottom
plate and change the battery. Please do not touch the circuit board while the
bottom plate is off or you risk damaging a component.
