Centauri – Harby Pedals All the mythic tone of the legendary Klon Centaur without the four-figure price tag, the Harby Centauri is a faithful, high-quality recreation built with premium components including genuine Texas Instruments op-amps and NOS germanium clipping diodes. Transparent, clear, and wonderfully touch-sensitive, it works equally well as a transparent overdrive, a clean boost, or a always-on buffer to keep your signal strong and singing from the first pedal to the last.
