PreSonus TubePre V2 Mono Tube Preamp

Live or in the studio, the TubePre V2 Mono Tube Preamp from PreSonus is a great-sounding tool you’ll use on a variety of sources. Use it as a straight-up tube preamp or a dynamite direct box (DI) for guitars and basses. Affordable, compact, and built into a rugged chassis with travel in mind, the TubePre V2 provides all the extras you need in a mobile and versatile preamp.

The TubePre V2 employs XMAX Class A solid-state preamp, followed in the signal path by a 12AX7 vacuum-tube stage. A dual-servo (no capacitors) gain stage lets you boost the signal to smoking hot levels without significantly increasing noise. Discrete components and high-voltage operation offer dynamic range and detail not found in other single-channel tube preamps in its class. Built tough enough for serious gigging, the TubePre V2 is a great choice for guitars and microphones alike.
