For 14 years, the famous BOSS FV-300 served as an industry-standard volume pedal. The tradition continued with the FV-50 series, but now the bar has been raised with BOSS's FV-500L pedal. This tank-tough diecast pedal is designed to meet the needs of the most demanding performers. It offers a stylish design, a road-tough build, a tuner output, and a comfortable, smooth action. It also provides an Expression output for use with expression-compatible amps, effects, and even synthesizers. The pedal's feel (torque) can be easily adjusted to suit each player's pedaling preference.
