Mooer's Purer Octave provides guitarists with 15 different polyphonic octave effect combinations in addition to one detune effect. The DSP algorithm separates the high and low input frequencies to ensure every preset operates seamlessly without spectral artefacts or distortions. These two frequency bands can be isolated or combined dynamically through the independent "SUB" and "UPPER" dials, allowing guitarists to finely craft the perfect effect to suit their specific needs.

Despite the minimalistic interface, Purer Octave users can still save their own presets by using the pedal's three-way toggle switch. Guitarists can choose whether to use the pedal's dials in real-time to craft their sound and once they are satisfied with the effect, they can leverage the three-way switch to save their favourite effects.
