From Sola Sound : For a relatively high gain silicon fuzz circuit this thing is smooth, like real smooth, a soft smooth you could say. Make no mistake this blue cyclops will fart-out a chewy smoke laden fuzz cloud you can really get your teeth into but will do so with a degree of etiquette. Bourbon as mouthwash holes punched through corrugated cardboard kinda tones but delivered to your ears with an air of refinement. No mad spazzed out oscillation and no frying eggs soundtracks going on in the background. In other words, it's a smartly designed circuit. Very simple, but thoroughly thought out”
