Top 10 best-selling Bass Pitch Shifters

The Gamechanger Audio Motor Pedal offers an electro-mechanical synth voice that takes your music to new heights. With unique modes and an expression pedal, you create sounds full of energy and intensity, full throttle!

The Nano POG is the smallest member of Electro Harmonix's POG family. It has separate octave-up and octave-down knobs, a dry mix knob, a separate output for your dry signal, and offers phenomenal tracking.

The Boss XS-100 Poly Shifter offers unprecedented possibilities for pitch shifting, while preserving the natural sound of your instrument. Suitable for both guitar and bass guitar.

The Electro Harmonix Micro Pog delivers the same effect as the original Pog it has been modelled after, but comes in a modern die-cast housing. Octave away!

Thought things couldn't get any smaller than the Micro POG and Nano POG? Well, think again! Electro Harmonix just released the extremely compact Pico POG Polyphonic Octave Generator stompbox.

The Keeley Octa Psi Transfigurating Fuzz pedal mercilessly mashes up a pitch-shifter with an octave generator and an analogue fuzz before neatly shoving it all inside one tight metal box.

To put it boldly, the Pitch Fork+ from Electro Harmonix is twice as powerful as its bite-sized predecessor and has two independent pitch-shift engines to give you all the functionality and tight tracking of the original Pitch Fork.

Boss reveals the next step in their famed OC Series of compact pedals: the OC-5. Compared to the OC-3, this fresh model boasts improved polyphonic tracking, extremely low latency and even the sounds from the OC-2.

The MXR M280 Vintage Bass Octave pedal blends the much-loved warmth of analogue sub with ultra modern tracking and a nice layer of extra headroom, and is built for the bassist seeking an organic, wide-ranging octaver.

The Bass Octave lowers your bass signal by an octave in two different (adjustable) ways. It produces a suboctave with a powerful mid range as well as a heavy, round-sounded version.
