Walrus Audio's Warhorn is a reliable companion of an overdrive that brings out a transparent, mid-range drive to carry along rhythm tracks or crank up and take leads. The Warhorn's two clipping modes, accessed by a two-way toggle, swaps between a more compressed, symmetrical clipping structure in the up position, and a more open, asymmetrical clipping structure in the down position. Between this toggle and the Warhorn's four responsive and reactive tone controls, the pedal rolls through a spectrum of tones. The Warhorn is a perfect right-hand, "always on" boost or drive for any player to introduce some warm, transparent breath to their signal.
