For 14 years, the famous BOSS FV-300 served as an industry-standard volume pedal. The tradition continued with the FV-50 series, but today the bar has been raised with BOSS?s new FV-500L (low-impedance) and FV-500H (high-impedance) pedals. These tank-tough die-cast pedals are designed to meet the needs of the most demanding customers. The pedals offer a new stylish design, a road-tough build, and a comfortable, smooth action. Both models also provide an expression output for use with expression-compatible amps, effects, and even synthesizers.
