PreSonus BlueTube Stereo Tube Microphone Preamplifier with Instrument Input Reviews
10 out of 10
"Important Piece in my Home Studio."
I use a tascam 424 MKIII as the foundation for my home studio. The Blue Tube was a good addition for a number of reasons.
First off.. when you use it RIGHT you do get tube warmth added to your sound. Yes, you can get noise.. ever see a tube that couldn't be pushed into noise? But I've compared this to the same tube in my digitech rp7, and my fender hot rod deluxe.. using guitar.. and the blue tube is as quiet, and they all sound very similar when you have the settings duplicated as close as possible.
I love this for my vocals, and my bass, especially...I use the blue tube now and then with my Nady CL5000 compressor for clean guitar sounds.
I want to add another blue tube so I can have it for the four main channels of my studio.
I'm glad I bought it, I'm happy with it's behavior and construction.
If you're recording at home, and are on a budget, there ARE good units out there that will fill the bill.. and this is one of them.

"Blue Tube: Delicious Like Sour Cherry Pie"
Feature:
BT has everything you'd need, and the bal/unbal input jacks are very cool.
Quality:
Seems very solid- apparently you can run extremely hot signals through the input without frying it.
Value:
Can't get a better two channel preamp for the price.
Desirability:
Very sexy. The ladies love it- all I need to get lucky is my trusty Blue Tube. BT is a classy looking unit, and it doesn't take up a bunch of space like some of those non rack mounted units with the tube stickin out the top. The sound really suits my taste- which is usually never satisfied. I run all my digital gear through BT to warm things up, and for that sweet mildly dark tone.
Sound:
Heavy, pretty dark. Very clear- you can dial in tons of drive before getting distortion.
Support:
Haven't dealt with Presonus, but I'm sure they're nice people.
Overall:
I'll use my Blue Tube forever. That may be the kind of stand up guy I am, but the preamp is worth it. I probably won't get another one until it breaks beyond repai, which hopefully is never- I also hope the tube is replaceable. I recommend this unit all the time, too. Unless you really dig an ultra bright tone on everything, this is your next preamp.
