Cleo™ commands the lower end of the gain scale anchoring Blues, Roots, Indie Rock and even doubles as a hearty Boost, while it enhances, not covers up, the sound of your instrument. With sweet, open top end clarity and not too much saturation, it allows you to craft anything from a subtle boost up through urgent mid gain drive to harmonically-rich overdrive, all in the spirit of Tradition.
