The VM-PRO resolves many of the common issues with volume pedals that cause tone sucking and mismatching problems. The VM-PRO works with electric, electro-acoustic, baritone or bass guitars. It also works with many other acoustic and electric instruments including electronic keyboards, steel guitars, and instrument microphones such as harmonica and horn mics.
Mission Ultrasweep™ volume control technology is designed for exceptionally smooth volume swells. Essential for certain styles of music such as ambient and P&W, Ultrasweep is unique to the Mission VM-PRO using a combination of custom potentiometer design and proaudio preamps to ensure perfect volume control for any instrument and any style.
VM-PRO includes on board buffers, isolated tuner out, sparkle control, and compatibility switches for use with active and passive pickups and fuzz pedals. The PZ version provides a 10M ohm impedance for use with passive Piezo pickups.”
