Centavo – Warm Audio Warm Audio's meticulous take on the mythical Klon Centaur, the Centavo delivers all the transparent, touch-sensitive overdrive tones that made the original a holy grail pedal, without the eye-watering price tag. From pristine clean boost to silky edge-of-breakup grit, it sweetens and enhances your tone at every setting, and the rear-mounted MOD switch extends the low-end response for a throatier, fuller drive on the bottom strings.
