Behringer FC600 Heavy-Duty Foot Pedal For VolumeThe Behringer FC600 Heavy Duty Foot Pedal for Volume and Expression Control allows you to get louder, softer, or expressive using the unit's torque controlled variable resistor. It works equally well for either volume or keyboard modulation control with high impedance instruments. Suitable for both the studio and the stage, the pedal can be used to change volume levels for lead parts or adjust the presence of your instrument within the larger mix.
