Built with the classic three-knob interface of level, tone and drive with the added functionality of a Phat (bass presence) switch and Clipping switch for toggling between uniquely voiced diodes, the Oxblood takes the classic overdrive/boost combo and gives it a brimming cup of distortion. Billed by Robert Keeley as the "Klon Killer," the Oxblood gives you all the transparent overdrive goodness you'd expect in a klone with the option for a mid-range gain sear characteristic of the Tube Screamers.
