The 1/4 in. jack provides a high Z input on the front panel for instrument preamplification.The BlueTube is housed in a half rack space steel chassis with a high-quality, anodized aluminum front panel.

"Blue Tube: Delicious Like Sour Cherry Pie"
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.
Sound
Heavy, pretty dark. Very clear- you can dial in tons of drive before getting distortion.
Features
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.
Manufacturer Support
Haven't dealt with Presonus, but I'm sure they're nice people.
The Wow Factor
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.
Musical Style:
... maybe a cross between Ween, Flaming Lips, and Frank Zappa
