The Perseus Dio takes the concept of the original model much further, offering a 3-voice lower octave analogue pedal with adjustable octave filters. 3 settings control the mix section, giving you low octave, double low octave and light saturation with boost. The Dry setting gives you an excellent light saturation sound capable of pushing your amp into overdrive, but the magic happens when you control the levels of the lower octaves with their associated low-pass filters. Unfiltered, the octaves are harmonically rich square waves that sound like a retro Nintendo, but by increasing their associated filter settings, the harmonics soften and turn into pure octaves.
Settings :
Down 1: Signal level of the lower octave.
Filter 1: Cut-off point of the Down 1 low-pass filter.
