Octa is a digital octave stompbox for both guitarists and bassists. Two octave voices blend with dry level control and support polyphonic processing in the default mode, so playing a chord is absolutely no problem. And there is an additional DIRTY mode which simulates the classic analog octave pedals (single note processing and a different tone).
