Pro MPA II : ART Pro MPA II - Good low budget preamp and even better when tuned up!

The appearance of the ART Pro MPA II looks like a solid quality product. It is well laid out and there are no complaints of visual quality. Even all electronic components inside the unit are in order and well organized.

The only negative matter I can think of is the 12AX7 tubes that are installed at the ART factory. They are harsh and cheap. Replacing them with vintage Telefunkens, Mullards or other high quality NOS tubes will give a more pleasing sound with softer treble, rounder bass and smoother middle.

The unit gives certainly enough gain for all types of microphones! Impedance trim pot is definitely a big plus for fine tuning treble and high mids. As a guitar and bass preamp or DI box the ART Pro MPA II really enhances the sound by digging out more different timbres of instruments.

Highly recommended product!
