Amazing functionality and quality for the price. The sound quality, in my opinion, is excellent. I tried a terribly crappy vocal mic with it, and the MP Studio made it sound decent. My SM57 sounds amazing going through it. I highly recommend it for any audio situation as I'm sure you'll find a good use for it.

I normally do not rate as high, but for the price and the application of this product it was totally worth it. For a single channel pre-amp, especially paired with a decent microphone of choice, it has been wonderful. Sound quality is superb, and it has a warm tone once tuned to specifications. I would definitely suggest for anyone testing out the waters of light audio editing/production as well as podcasting.

I have the ART TPS-II, which is basically a 2-channel rack-mount version of this unit with presets, and I'm very happy with it both live and in the studio. I'm probably going to buy a couple of these units as extras & to keep in my "gig box". These would make great gifts for guitarists or keyboard players to add a little "oomph" to the signal & tone.

Thats about it, a real cheap way to get some more volume for your mic/vocalist. Its a little noisy. I think I am going to experiment with a better quality tube and see if that doesn't help a bit. Really though for the price you can't beat it for what it does.

This is the second MP PreAmp that I have pirchased. The first ended the feedback problems that follow harmonica players around as they look for more volumne. Plenty of volumne, no feedback, problem solved. The second was for an accustic mandolin with an external pickup. Internal hollow body feedback was a problem as the nobs are twisted at the amp. The ART MP controled the gain side of pickup while allowing for plenty of amp volumne. Problem solved. This is a great piece of equiptment for live performance.
