MIDI-controlled AB pedal
This compact yet powerful device allows you to seamlessly switch between two instruments such as guitars, stereo synthesizers, or other line-level gear using either a foot switch or MIDI control.
Because of its passive true-bypass design, it can also function as a stereo A/B box when connected in reverse.
