The VM-PRO-PZ-BK is the first volume pedal specifically designed for piezo pickups. Standard volume pedals work in conjunction with piezo pickups only conditionally, the sound becomes matte and thin. The input impedance of the Mission Engineering pedal is adapted to piezo pickups, with the Sparkle switch you can compensate for treble losses when you turn the pedal down. A high-quality buffer circuit allows long cable paths without sound loss. A tuner output is also available.
