A fan favorite - the Arion brand was well known for their plastic effect boxes that directly competed with Boss during the 1980's. These Japanese effects have some of the sought after tones that people are chasing - just look at jazzers like Michael Landau using their stereo chorus still decades later. This here MOC-1 Octave pedal is a great choice for those looking for an early OC-2 Bass Octave, maybe to get the Sledgehammer Levin tone, maybe to get the Lefebvre faux synth tone... maybe to just find something original all together. This unit comes to us in good condition with some mild cosmetic wear and velcro on the bottom. The plastic battery compartment is intact and present.
