This 'board-friendly 'Nano' version of the Small Stone has the same controls as the original: a Rate knob and a Color switch that changes the character of the phasing.
In its lower position, Color gives you milder phasing similar to the Phase 90, though not quite as warm sounding and with a faster max phase speed that can approximate a fast Leslie and even goes as far as a metallic ring mod tone.
Flick Color up for a deeper, stronger phasing with a more pronounced sweep that manifests itself as a vowelly 'wow' once the rate knob gets to 12 o'clock and beyond. At full rate, it's a classic 'underwater' sound.
Next to our 70s vintage Small Stone, the Nano can duplicate some of the sounds but gets much brighter in one segment of the sweep, so the dark-to-bright nature of its sweep sounds more intense and is especially notable at slower rate settings.
