BOSS FV-50L (Volume Pedal / Low Impedance) This is a standard BOSS volume pedal. It's the low impedance (L) model, suitable for connecting to keyboards, guitars after effects pedals, guitars with active pickups, and other devices with low output impedance. I bought it because I needed it, but I haven't used it much since then and have kept it in storage. It has been used infrequently, and it works without any problems. The exterior also has very few fine scratches and I think it's in good condition. This is a sale of the pedal itself only. Please refrain from purchasing if you are sensitive to used items.
