Steve Vai, the most prominent users of the American Morley pedals had to have a tailored working volume pedal. Unlike most existing volume pedals, the PLA Steve Vai impresses with its linear operation. The volume increase is therefore uniform and not by leaps and bounds as it is commun to see in pedals with logarithmic function is. The fine-metering is the great strength of Steve Vai's Little Alligator. Another extremely handy feature is the minimum volume knob and a fixed volume setting.
