Portable Tube Preamp for Your Projects!

The Tube MP is the world's most popular external tube microphone preamp. Whether you're working with a digital, computer or analog recording system, the Tube MP's TEC Award-nominated design will allow you to obtain professional recording studio results at a fraction of the cost of comparable equipment. Now it's available in a portable version! The Tube MP ps (Project Series) employs ART's hybrid design that allows it to add warmth and fatness to a signal while maintaining exceptionally low-noise and high quality. While its primary application is being used with a microphone, the Tube MP ps is an exceptional direct box - impedance matching, amplifying, and improving the sound of any instrument plugged into it.

Using an external mic/line preamp has become increasingly popular over the past several years. The Tube MP ps offers superior performance and sound quality compared to the "onboard" preamps found in many low-cost mixers and multi-trackers. Its sound has been consistently favored over other products that cost more than 10 times as much. The Tube MP ps offers professional quality sound combined with pro features like a hand-selected 12AX7a tube, phantom power, and phase reverse. For a minimal investment, a Tube MP ps can provide the single largest improvement to the sound of your studio.

ART Tube MP ps Portable Preamp/DI Features:
  • Extremely low noise discrete front end
  • Up to 70dB of clean, "musical" gain
  • High-output signal drive capability
  • Fast FET limiter to prevent overload

The warmth of the Tube

I purchased my first unit 6 years ago. It still works like the day I brought it. I use it for a preamp on my banjo with humbuckers. In the studio I found that this preamp is great for vocals and acoustic guitar when connected to an AKG studio mic. It warms any sound when digital conversion is involved. I now have 3 of them. When you are not able to justify the need for their Opto 8 (8 channel) this unit covers it.

A must have!!!

For anyone who doesn't already have one needs to get one ASAP! Awesome sound without any hiss! Thanks to Devon on the Sweetwater Team for always looking out!

Tube MP/Customer Service

First off, Sweetwater's customer service is phenomenal! My sales rep, Josh Estock is awesome. He's always super patient and ready to answer any questions I might have (even if I decide not to pull the trigger). Then there's the Art Tube MP... this thing made a night and day difference in capturing audio through my Focusrite 2i4. In the past it seemed like I couldn't ever get enough gain for my Studio Projects multi-pattern condenser mic, but this thing changed the game and got me to that sweet spot. In addition to solving my gain issues, it's seems to have subtly given my tracks a rounder and warmer tone. I also appreciated how solid it was built. Maybe I'm just still in the honeymoon phase, but I love this thing, it does all that I needed it to.

I'm A Believer

I've grown accustomed to using some amazing preamps and I was about sceptical concerning this one. This pre has added so much clarity to my recordings. I have a Saffire Pro 14 interface and I use the Blue Bluebird as my main vocal mic. I must say this pre does the job and I'm completely satisfied with it.

I needed this in order to add warmth to my spoken word projects. I use an Apogee Duet 2 and while its pre-amps are very clean and crisp, they are too much so for audiobooks. I wanted that vintage, barely perceivable distortion that I had heard on audiobooks in the past and so a "valve preamp" was the way the go. I was reluctant to spend a large amount on what was essentially an experiment, so I chose the ART Tube MP after a lot of research. Within minutes, it was clear that I had made the right choice. Warm, vintage and quiet. Perfect for my needs.
