And the overdrive creates a tone well-suited to heavier genres вЂ“ rock, progressive rock, metal, and so on. ItвЂ™s not hard to see why itвЂ™s called the Powerchord, though, because with the harmonies it creates, you will literally have a power chord with every note you play!ДЄs you would expect, you can get some huge sounds out of your bass using the Powerchord, almost as if you were playing a bass with double course strings. It accepts active or passive instruments and has a battery life of 20 hours. This pedal also comes with noise gate, overdrive, tone, and effects level controls. The more switches you activate, the bigger the harmonies. The onboard LEDs help you see which harmonies youвЂ™re about to activate before you switch them on. It creates stacked harmonies above the root note an octave up, and octave and a fifth up, and a fourth and an octave up. The Fishman Fission Bass Powerchord pedal is more than just an octave pedal. Package dimensions: 8 x 7 x 3.5 inches Fishman Fission Bass Powerchord FX Pedal Some users were a little disappointed in the quality of the build, though, especially considering the price. Most users loved the POG2, and they even found they were able to create cello and organ like sounds using this pedal. Just know that it doesnвЂ™t always track lower notes all that well. IвЂ™m not convinced thatвЂ™s the best way to utilize it, but it does allow you to create some interesting sounds.ДЄlthough the POG2 is often used by guitarists, it sounds quite good with a bass too. Since itвЂ™s a polyphonic octave generator, it can handle chords too. The POG2 makes it easy to add octaves below and above, and together can create a huge sound. This is a versatile pedal with many controls вЂ“ thereвЂ™s a section for the octaves, a section for effects (attack, lowpass filter, and detune), buttons for Q (resonance) and Dry/FX (allows you to apply to your dry signal), and finally preset controls for cycling through presets. This pedal comes with attack control, two sub-octaves, two-pole resonant low-pass filter, enhanced detune and algorithm, and a rugged die-cast chassis.

This one is the Electro-Harmonix POG2 Polyphonic Octave Generator.

When it comes to octave pedals, POG is kind of the king, and we have more than a few POGs to highlight on this list.
