PreSonus TubePre V2

A versatile preamp with impressive dynamic range and detail.

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.
From gentle warmth to total fuzz with the twist of a knob.

XMAX microphone preamps deliver incredibly high headroom, deep lows, smooth highs, and a rich overall sound garnering them rave reviews from users and the media alike. The 12AX7 vacuum tube that follows the XMAX in the TubePre V2 was hand-selected and carefully tested for electrical conformity and freedom from microphonics. Twist the Drive saturation control to add the “color” that only a hand-selected 12AX7 can deliver — from gentle warmth to total fuzz.​
A versatile tool that’s built to travel.

Housed in a rugged case that is built to travel, the TubePre V2 rear panel sports separate unbalanced, ¼” instrument and balanced, XLR mic inputs and unbalanced ¼” and balanced XLR line outputs. Use it as a straight-up tube preamp or a dynamite direct box (DI) for guitars and basses. We’ve provided all of the extras you need, including a highpass filter, phantom power, polarity reverse, and a backlit VU meter. Yet with all its features, it’s small enough to carry almost anywhere—or simply screw-mount it to a standard rack tray.
Great sound, live or in the studio.

Live or in the studio, the TubePre V2 is a great-sounding tool you’ll use on a variety of sources. Add just the right amount of tube distortion to guitars, basses, and mic signals. Go lightly for gentle warmth or go all-out for solid crunch—it’s up to you. So give your ears a treat and test the TubePreV2 at your favorite PreSonus® dealer. Then check out the price— and prepare to be amazed. Because with PreSonus, big sound does not have to cost big money.
