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, thatâ€s it really. You can dive into wide and rich sound textures that make your guitar sound larger than life! And, as most of Joyo's pedals, the Ocho is also True Bypass.
