Octaver / Pitch shifter for bass guitar

A bass octaver adds an octave to the played note, while a pitch shifter changes its pitch across a broader range, and both can create new layers or distinctive lines. Use an octaver to thicken a riff and a pitch shifter for melodic shifts or less conventional tone colours. Choose the effect by the interval or type of signal processing you need. Compare the functions, number of controls and connections that suit your rig.
