The Mission Engineering VM‐Pro Volume Pedal brings some of the most sophisticated elements ever available in a volume pedal to the fore with selectable passive or active input, built-in studio-grade buffer and line driver, and a selectable output for handling those tricky vintage pedals. Not content to stop with there, the all-metal chassis is built for years of use in touring or around-town performances, and it's all rounded out with a unique sparkle switch for retaining highs when rolling back on the volume.
