Electro-Harmonix Pitch Fork Polyphonic Pitch Shifter Pedal (Demo by Bill Ruppert)

The Electro-Harmonix Pitch Fork polyphonic pitch shifter pedal transposes an instrument’s pitch over a +/- three octave range and features three modes which allow the pitch to be transposed up, down or both, simultaneously. The pitch shift amount can be set to a fixed interval or continuously varied by an expression pedal or control voltage.

The controls are straightforward and intuitive. An 11-position Shift switch selects the maximum transposition interval ranging from D (Detune), a shift of 17 cents, through Minor 2nd, Major 2nd, Major 3rd, Perfect 4th, Perfect 5th, Major 6th, Minor 7th, 1 Octave, 2 Octaves and 3 Octaves. A three position toggle switch controls whether the pitch is transposed up, down or both. In Dual mode, two pitch-shifted signals are output. One follows the shift knob as if in the Up position while the other creates a harmony. Dual Mode settings include M3 up + P5 up, P5 up + 1 Oct down, 1 Oct up + 1 Oct down and many others. A Blend knob controls the mix of the dry signal and the effected signal, and an EXP jack enables the player to control pitch and glissando with an expression pedal.

The Latch button selects Latch or Momentary mode which affects how the footswitch and EXP input behave. In Latch mode, the footswitch toggles between effect on and buffered bypass each time it’s pressed and the EXP input continuously varies pitch. In Momentary mode the effect is only on while the footswitch is depressed and when it is released the Pitch Fork goes into bypass.

In Latch mode the EXP input controls pitch shift amount, ranging from unity to the interval set by the Shift knob, and pitch varies continuously throughout the expression pedal’s range. In Momentary mode the EXP input controls glissando rate for the Pitch Fork’s footswitch. When the bypass footswitch is pressed, the Pitch Fork jumps from bypass to the interval set by the Shift knob. The amount of time it takes to reach that new note is the glissando rate. When the footswitch is released the pitch will return to unity at the same rate. That glissando time can vary between 4 milliseconds to two seconds depending on the heel/toe position of the expression pedal. The default glissando rate is 60 milliseconds when nothing is plugged into the EXP input.

The Pitch Fork comes equipped with an EHX 9.6DC-200mA power supply and also runs on a 9Volt battery.

EHX is really inovative. Instead of just creating another overdrive that try to imitate 1960's tube amps they create future-guitar sounds.

[guitarvibe]

5:29-6:20. Most innovative use of a pedal I've heard in a long time. So f*ing sold.

[DanielPestanaTranslations]

I just came back to say that this has become the most important pedal in my board. It helped me create the arrangements I had in my head and was never able to get them out, until I got this. Thank you EHX!

[IantaylorCanuck]

This is a ridiculously useful pedal. I play in a 2-man band doing lots of heavier stuff, often in conjunction with a looper. With the Pitchfork I can get a bass sound, loop it, then play over top. Also we do lots of tuned down (e.g. C# for QOTSA) and it's perfect for that. I also like the faux 12-string thing. I'm glad the sales guy talked me out of the POG.

[vdreaming]

If you guys could just go ahead and ship me one of everything, that'd be great.

[racerx]

Ive never seen such a convincing demo, hats off! Also +1 for Audioslave at the end

[aliensporebomb]

Bill's fingerings are amazing.  EHX does it again: another box we all have to have!

[artysanmobile]

This is amazingly good pitch shift. Easily the best I have ever heard in a stomp box.

[ckrug]

Had my eye on a Whammy for many years. Recently been drooling over the Meris Hedra. But once I saw this demo, I realized this is the pedal with the sound and capabilities I’ve been craving all along. Just ordered one, can’t wait! 🤘

[RayCelona]

One of the best sounding pitch shifters I've heard!

[cast]

I remember in the 70's when EH had a store on 48th st.in NYC.The room or store was dark and it had a small stepup stage like a rehearsal studio, and some guy came out and would demo all the pedals EH had out at that time.I also remember seeing  a Mesa combo, with a honey comb grill, maybe a MKIIC+ dont really know but it was loud as fuck.I remember becoming obsessed with the Deluxe Memory Man.So glad EH is still alive today!!!!Those are some great memories I have as a kid learning to play guitar..

[Finvaara]

I bought one of these earlier today because it was the only octave pedal I could find. I had no idea it was capable of so much more than I expected, and I'm super thrilled.

[travissmith]

the solo from like a stone, well done.

[coatlecue]

your implementation of that surprisingly useful device has caused me to dip into my mad money. I'm already slobbering with anticipation. love those chords towards the end, and the tasteful use of what sounds like one of EH's classic big triangle-ly phasor/ flanger thingy. nice

[GuitarAnthony]

<puts head in hands> EHX will not be satisfied until they have all my money.

[davidfields]

Fusion of a POG and a Sweep Octave Pedal and Detuner.... God... This guys are cool!

[bigmaz]

Why the fuck is nobody talking about 1:48 that's the most godly thing on this earth

[KestrelJo]

Wow! This sounds far more natural than the POG2 or the Octron or anything else I've tried to get great tones. I think this will totally do it for simulating bass. I want this!

[noah-gdesign]

This has to be one of the best Pitch Bending pedals I have ever listened to.

[cindileavingscarlet]

You are a fantastic guitar player!! Love this pedal!
