Crafted with features like a tuner-output jack, adjustable pedal torque for nailing the perfect feel for your preference, and a dual function as an expression pedal, the Boss FV-500L Volume Pedal is a quality pedalboard staple with a few extra nifty tricks. Optimally designed for low-impedance scenarios like a longer pedal chain, the FV-500L integrates well within large effects-driven rigs and is built to go the distance for years in a diehard aluminum chassis.
