Distinguished by a durable steel chassis, intuitive minimum volume knob, and a built-in 20dB gain boost that drives your volume straight into overdrive, the Ernie Ball MVP Volume Pedal pairs the best of two essential effects into one diehard unit. Immensely sweepable, the velvety response on this unit works seamlessly with both passive and active electronics for a pedalboard staple ideal in post-rock, metal, or psychedelia.
