The ART Tube MP Studio V3 brings several, high-end features to the sub-$100 preamp range.

The V3 stands for "Variable Valve Voicing" technology which enables you to select different kinds of tube coloration (or none at all) with a radial switch.

An output limiter protects your signal in the case of sudden transient jumps or dynamic performances.

A built-in VU meter lets you set gain levels more accurately than relying on your DAW.

Pros

It's all about harmonics. Users love the fact that they can tune the level of coloration according to their sound source. The V3 settings were also open to experimentation with one user noting that the bass setting works well for vocals. Portability is also seen as a plus.

Cons

No balanced jack output.

Overall

If you want a portable tube pre with several voicings for various instruments and sound sources, the ART Tube MP Studio V3 is an excellent choice.
