Electro harmonix Synths, Pitch Shift & Octave Fx

Electro Harmonix Synths, Pitch Shift & Octave Pedals. All of The Electroharmonix Octave, Synthesis and Pitch Pedals take the notes you play and synthesize new waveforms and pitches from those notes with added controls over filtering and in some cases dynamics. Not only can you make your guitar sound like bass but you can also change the sound of your guitar into a monophonic synthesizer with a slow attack or quick filter sweep. Turn your 6-string into a 12 or 18-string. Freeze your chords and play new licks over the frozen chord.
