The Oxblood takes the tones of the mythical Klon Centaur and expands on them for a far greater pallet of tones ranging from crystal cleans to huge drive. The Phat switch allows you to toggle from the classic Klon/Tubescreamer bass-cut tone to a full range mode that lets all the glorious lows through for maximum girth. The Clipping switch accesses higher gains than normally available on a pedal with this voice.
