Presonus TubePre V2 1 Channel Tube Preamplifier DI Box

Compact and affordable, the ever-popular TubePre V2 professional tube preamplifier employs our popular 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.
