The JOYO “Ocho” is an octave pedal, as the name suggests. The controls are as simple as can be: you can control the level of both octaves with the OCT1 and OCT2 knobs and the overall volume with the LEVEL knob, that’s it really. You can dive into wide and rich sound textures that make your guitar sound larger than life! And, as most of our pedals, the Ocho is also True Bypass.
