television reception, which can be determined by turning the equipment off and on, the user is

encouraged to try to correct the interference by one or more of the following measures:

•

Reorient or relocate the receiving antenna.

•

Increase the separation between the equipment and receiver.

Pitch Fork

POLYPHONIC PITCH-SHIFTER/HARMONY PEDAL

Congratulations on your purchase of the Electro-Harmonix Pitch Fork, a compact,

battery powered, polyphonic pitch-shifter/harmony pedal. The Pitch Fork transposes

the pitch of your instrument over a range of up to +/- 3 octaves. Three different

available pitch-shifting modes allow the pitch to be transposed up, down or both

simultaneously in Dual mode. The pitch shift amount can be set to a fixed interval or

continuously varied by an expression pedal or control voltage. The Pitch Fork’s

footswitch features two different modes of operation: Latch and Momentary.

Momentary allows rapid toggling between effect and bypass for quick blasts of pitch

bending. The BLEND knob is a wet/dry control allowing you to create the perfect mix

of your dry and transposed signals.

WARNING: Your PITCH FORK comes equipped with an Electro-Harmonix 9.6DC-200BI power

supply (same as used by Boss

& Ibanez

: 9.6 Volts DC 200mA). The PITCH FORK requires

30mA at 9VDC with a center negative plug or runs off a 9Volt battery. Using the wrong adaptor

or a plug with the wrong polarity may damage your PITCH FORK and void the warranty.

GETTING STARTED

Connect the output plug of the supplied power adaptor to the 9V power jack. Plug

your instrument into the INPUT jack; connect your amp to the OUTPUT jack. Set the

toggle switch to UP arrow and press the LATCH button so it is down. Turn BLEND

fully clockwise and set SHIFT to 1, as in 1 octave up. Press the footswitch until the

LED lights up. You will hear all your notes shifted up 1 octave. Connect an optional

expression pedal to continuously vary the pitch from unity up to 1 octave.

Press the LATCH button so it is up. The footswitch now has a momentary action:

when pressed the effect activates and pitch is shifted; when released, the effect is

bypassed. Connect an expression pedal to control glissando rate of the momentary

footswitch. If the EXP jack is vacant, pitch will change at the default glissando rate of

60ms (this is user adjustable).

BLEND KNOB

The BLEND knob mixes between the untreated, analog dry signal and the effected

signal. At BLEND’s full clockwise position, the output is 100% wet.

SHIFT KNOB

The SHIFT knob selects the maximum interval of chromatic transposition. The chart

below shows how the pitch will be shifted relative to the original pitch.

MODE TOGGLE SWITCH

The MODE toggle switch selects whether the pitch is shifted up, down or both

simultaneously relative to the root. Dual mode outputs two pitch-shifted signals. One

of the shifted signals follows the SHIFT knob as if in UP mode. The other shifted

signal creates a musically useful harmony according to the SHIFT knob setting.

LATCH BUTTON

The LATCH button selects Latch or Momentary mode. This affects how the footswitch

and EXP jack input behave. When the LATCH button is down, Latch mode is enabled.

The footswitch toggles between effect and bypass each time you press and release

the footswitch; the EXP input continuously varies pitch. When the LATCH button is in

the up position, Momentary mode is selected. The effect is only on while the

footswitch is held down, otherwise the Pitch Fork is bypassed; the EXP input varies

the glissando rate of the momentary footswitch.

BYPASS FOOTSWITCH & STATUS LED

The footswitch toggles between effect on and buffered bypass. In Latch mode, each

press and release of the footswitch toggles between effect and bypass modes. In

Momentary mode, when the footswitch is held down, the effect is on, when the

footswitch is released, the Pitch Fork enters bypass. The status LED lights when in

Effect mode.

EXP JACK

EXPression input jack accepts a TRS expression pedal connector or a Tip-Sleeve 0-5V

control voltage input. The expression pedal should ideally use a 10k potentiometer

with linear rather than audio taper. It must have the wiper connected to TIP and toe-

down connected to RING. Pedals made by some manufacturers do not conform to

this convention, and would need a special cable to swap RING and TIP.

FV-500L.

 LATCH MODE - the Expression/CV input controls pitch shift amount,

ranging from unity, or no pitch shift, in the heel position to the interval set

by the SHIFT knob for the toe position. Pitch varies continuously from heel

to toe in all settings.

 MOMENTARY MODE - the Expression/CV input controls glissando rate for

the Pitch Fork’s footswitch. When the bypass footswitch is pressed, the Pitch

Fork jumps from bypass to the pitch shift interval set by the SHIFT knob.

The amount of time it takes to reach the SHIFT knob’s interval setting is the

glissando rate. When the footswitch is released, pitch will return to unity by

the same rate. When your expression pedal is heel-down the rate is 4ms, in

 toe-down the rate is 2sec. When no device is plugged into the EXP input the

default glissando rate is 60ms.

SAVING NEW GLISSANDO RATE SETTING FOR PITCH FORK FOOTSWITCH

1) Set LATCH mode button to the Momentary or up position.

2) Connect expression pedal or CV device to EXP jack.

3) Press and release Pitch Fork’s footswitch while adjusting expression pedal or CV

device until you hear desired glissando rate. Leave external device in current

setting.

4) Press and hold down the Pitch Fork’s footswitch.

5) Press LATCH button so it changes to Latch mode. LED flashes to confirm.

6) Release the footswitch.

7) The new glissando rate is now saved. Remove plug inserted into EXP jack,

change back to Momentary mode and use footswitch to confirm new rate.

RESTORING FACTORY DEFAULT FOR GLISSANDO RATE

1) Make sure nothing is plugged into EXP jack.

2) Set LATCH button to Latch mode, the down position.

3) Press footswitch so that Pitch Fork is in Bypass.

4) Press and hold down the Pitch Fork’s footswitch.

5) Press LATCH button so it changes to Momentary mode. LED flashes to confirm.

6) Release the footswitch.

OUTPUT JACK

Outputs the wet/dry mix set by the BLEND knob.

CHANGING BETWEEN LATCH AND MOMENTARY WHEN EXPRESSION PEDAL

IS CONNECTED

When in Latch mode and you switch to Momentary mode the expression pedal

position is ignored. The stored glissando rate will take precedence until the

expression pedal is moved from current position.

LED ON STARTUP

The LED will blink 4 times then hold on the 5

if in latch mode or toggle off if in

momentary. This happens when AC power is applied or you plug into the input jack

with a fresh battery installed. If battery power is too low, the LED blinks dimly, every

other second.

CHANGING THE BATTERY

To change the 9-volt battery, you must remove the 4 screws on the bottom of the

Pitch Fork. 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. To extend battery life, disconnect the INPUT jack

when the Pitch Fork is not in use.

NOTES AND SPECIFICATIONS

• PITCH FORK has high quality buffered bypass.

• Input impedance is 2.2MΩ.

• Output impedance is 680Ω

• Current draw of the PITCH FORK is 30mA.
