Twist the TubePre V2 Drive saturation control and add the color that only a hand-selected 12AX7 vacuum tube can deliver from gentle warmth to total fuzz. Unlike other compact tube preamps, TubePre V2 starts with the low noise, high headroom Class A XMAX preamp input stage found in our premium interfaces and digital mixers. Discrete components and high-voltage operation deliver best-in-class dynamic range and detail not found in other single-channel tube preamps.
