Enlarge your tone. The Electro Harmonix Pitch Fork Polyphonic Pitch Shifter will transform the sound of your instrument. If you've ever wanted to make it sound super low or screamingly high, this pedal will serve you well. It offers up, down, and dual modes, letting you shift the pitch of your instrument up or down up to three octaves.
 
In dual-mode, you'll get a beautiful harmony sound which is rich, deep, and full. And a simple two-knob interface makes for simple, no-nonsense operation, so you won't have to fiddle around for ages to get what you want. Whether you want to go low and rumbling or screamingly high, you can shift the pitch of your instrument instantly with this nifty pedal.
If you've ever felt your sound needs more variety, this could be a solution. With the ability to change the pitch of each note you play up or down three octaves, the Pitch Fork can add an array of new sounds to your arsenal. The Shift knob has 11 positions, with each representing an interval, so you can change pitch with accuracy. The Blend knob controls how much of the effect is blended with your original signal. In dual mode, your pitch will be shifted both up and down for a beautiful octave effect.
With an expression pedal, you'll be able to continuously vary the pitch of your instrument, adding even more flair to your music. And there's two further modes, consisting of latch and momentary. These affect the way the footswitch works, with latch turning the effect on and off, and momentary only turning the effect on whilst the footswitch is being pressed. This small pedal is super robust, and sure to make a huge impact on your sound.
