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

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.

ART tubeMP used with resonator

Thanks for all of your input into my "electrifying" my resonator. Here is what I did and if you like, pass it along. I installed a Fishman Pro-Res-001 passive pickup ($120) under the cone as instructed, drilling the jack hole in the center of the back below the string attachment endpiece. I used a tapered titanium bit, taping the wood to prevent splintering to drill the hole for the jack. Since I am not a luthier, it was my first time with this type of installation-it worked perfectly. I bought an ART tube preamp ($60) and plugged it into my Fender Acoustisonic amp. Here is where the experimentation came in: I used an unbalanced TS instrument cord from the guitar into the preamp and an XLR cable from the preamp into the mic input on the amp (I could have easily done the same with a PA). With a bit of tweeking for my ears, it worked perfectly and this resonator is now a "hot" instrument. The preamp is the ticket: user friendly, economical, diverse in its use. Your advice was spot on.

Nice product, shipped really quick would love doing business again.


I've worked with some of the super pricey preamps before, but I still prefer this thing! Once you burn in the tube, it produces a really warm yet transparent sound. It doesn't have a lot of fancy features, but that's one of its strengths. I run as much of my mics through this as I can. Some people make fun of me for using a $3000 mic with a $70 preamp, but I don't care!
