The Aguilar Octamizer - one of the most sought after octave pedals. it is working perfectly. Just a couple of scratches pictured above. always kept in a dry non humid room.

This is an analog bass octave pedal that adds a deep, smooth octave-down signal to your tone. It tracks low notes accurately and offers separate controls for clean and octave levels, plus tone shaping to dial in anything from subtle low-end boost to synth-like sounds.
