The analog octave divider.
 
MKIII is here. All the features of the MKII version packed into a smaller footprint. Cut the dry signal on the fly with the SUB footswitch and cross the astral plane into the THICC dimension. The circuit has been reconfigured as volume/volume and it sounds better than ever. The enclosure features an eye-catching new ULTRABLACK finish.
Controls: clean vol / octave vol / octave tone / TIM MODE / sub vol trimpot
