The JOYO R-13 XVI is a polyphonic octave pedal, meaning you can track multiple notes and you have a division of the low sub and the high upper octave. Both low and high octaves can be adjusted independently with the Sub and Upper knobs. You can also blend in your dry signal with the Dry knob. It also has this really cool, unique feature of the mod control which adds movement and modulation into the octave.
