The Dunlop DVP1XL Volume XL brings together big features for the modern demands of a volume pedal like adjustable rocker tension, an internal switch for alternating hell and toe values, and an expression output. Housed within a durable aluminum chassis designed for the demands of the road or the gig down the street, the DVP1XL incorporates Dunlop's patented Low-Friction Band Drive for the smoothest swells this side of the Pacific.
