The FBV Express MKII by Line 6 is a small foot controller designed to function with their line of POD modelers and Spider amplifiers, giving you totally hands-free control over your Spider or POD products. With a full sized expression pedal, a chromatic tuner, four channel switches, and more, the FBV Express MKII takes the functionality and ease of the FBV Shortboard and puts it in smaller, more convenient housing.
