The OC-3 is a successor that can produce innovative octave sounds, and it was the world's first to achieve a polyphonic octave! It can accurately produce octave effects even with chord input from a regular guitar signal! Furthermore, the RANGE knob allows you to adjust the range to which the octave effect is applied, so you can set it up to add octave sound only to the low frequencies, for example! Why we recommend the OC-3: It is highly recommended for those who want to use an octaver but don't know what to buy, or for those who want to distort the sound of an octaver! The OC-3 is currently discontinued by the manufacturer, so it is a valuable effector only available on the used market! The items in the photos are all that are included!
