Great for bass!

Wow, I read the reviews on this and took a chance. I play a passive fretless, and this little box gives me a warmth and creaminess to my tone. I really love how it sounds like I'm playing through a vintage amp. Definately recommend....I run this between my bass and my Zoom B3, then into the amp for live sound. For recording, I run the 1/4 out to my pedal and amp, and the xlr direct into the board. Talk about great tone!!!!

If you don't have it-get it

It's everything it's supposed to be for a very low price. I use it on my NS Design WAV electric upright bass at church (piezo pick-up). I needed something more than just a DI box to boost the signal to the mixer. This unit works great. Didn't need EQ, as I leave that to the sound guy.

Inexpensive yet has its use

Use it as a mic pre is just average, but if you run it as a bass DI, this thing can be a sleeper! The best $ you can spend for!

Great Product!

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.

Must have for ANY start-up studio

If you are looking for a piece of gear that will warm up your vocals and acoustic guitars, then you have found it. For the price there is nothing on the market that can touch this. I can tell you in our small studio we give this thing a work out, and it has never failed to impress or perform. Buy the ART Tube MP you will not be disappointed.
