I love using these for live sound. I've been using them for 6 years. They are really smooth on acoustic guitars! They compress the sound in a very natural and pleasant way. I'll use one of these over a passive direct box any day! I've been know to throw one of these even on vocals if I don't have a compressor available. This can be just enough to make the extreme dynamics tolerable and makes vocal simply sound better in the process. These small preamps have an unusual way of gluing together what goes through them. Dynamics are less extreme and subtle harsh details are pleasantly softened. At the same time all the pleasant sound are left alone or enhanced. Line outs on an acoustic guitars rarely sound anywhere near as good as the actual guitar. These make these line outs much more pleasant. I've recorded some live stuff that was just not pleasant or enjoyable sounding. Running it through one of these before I start mixing is often a life saver. I purchased a TubeFire 8 hoping to get multiple channels of the Tube MP sound, but it doesn't have it. In a live setting, perfectly transparent is often harsh and unenjoyable. These Tube MP's somehow make these kinds of things simply more enjoyable.

I bought two of these because I needed a couple cheap preamps to fill in for a while until I could get some better ones, but I didn't need to get better pre's after using these! I can't believe the quality of this preamp for such a great price! Very clear and subtle, even with phantom power. I recommend this to anyone looking for a good pre on a budget.

i have just bought two tube mp's over the last week and replaced the stock chinese tubes(hissy and microphonic) with a JJ 12ax7 in one, and a Groove Tubes 12ax7 in the other.Im impressed with how clean these things run even with the gain up high. Let's just say you will probably never use the 20 db gain boost. These things definetly smooth out the peaks and with enough gain you could probably forgoe using a compressor on bass and percussion.

Okay, this litle box is no $8000 preamp obviously, but I have used it on stage as DI to warm up my cello's/ acoustic guitar's somewhat harsh piezos, on bass (upright and electric); and in my project studio to track everything from vocals, to raps, to guitars, sax, bass...
Would I like to use an Avlon DI instead on my bass signls - sure, but i can't afford one!
This little box does more than any other under-$100- equipment-investment i have ever made and it does it well!!
Also check out their Project Series TubeMP that can be found in the Sugary H2O of Fort Wayne, IN (and on this website).

Tube MP adds nice color Sterile Digi recordings 
by Jerry L. Edwards from Brunswick, ME, January 2006

I record a lot of hip hop, both vocals and tracking the beats out into protools and e-magic logic. This lil' pre-amp always come through. From kicks and snares, to bass lines; and from rappers to smooth backup r&b-ish vocal stacks, the Tube MP delivers. Try it out, its cheap, but worth more than its weight in gold!
