Tube or solid state? It's got both!

The PreSonus BlueTube DP Stereo Preamp is among the most versatile two-channel mic and instrument preamps in its class. Its Dual Path technology lets you choose between two preamp stages: a transparent solid-state or warm tube preamp. Each gain stage of the BlueTube DP is pure Class A with high headroom.

Each channel of the BlueTube DP includes a -20dB pad, polarity reverse, 80Hz filter, and +48v phantom power. On the front panel you'll find controls for solid state gain and switchable on/off tube drive. When the tube drive is off, the tube preamplifier stage is bypassed delivering ultra-quiet and transparent solid state preamplification.

Large analog VU meters provide precise visual monitoring. Dual Neutrik combo jacks for microphones or instruments provides quality I/O and make the BlueTube DP great as a DI for electric bass and guitar.

Bluetube + Firepod

I've been recording with this bad boy for a little under a year now, and couldn't be happier with it.

I run my guitar through it, and then through a pedal, and then into Logic Studio for some EQ and tweaking and the sound I get is AWESOME! Turn the the tube all the way up and just barely add enough solid state to make it audible and you're set!

As far as vocals go, I avoid the tube for them, using only solid state, and it adds the warmth that everyone seems to be looking for.

Overall, great product for the price. Piece of advice: let it run for a few days to burn the tubes in before trying to record anything through the tube.

Some people are confused

This thing is a great tube pre amp for recording or live applications. Some people reviewing it I think are not quite sure how to use it. Is it the best pre amp out there? For an affordable price, yes. You simply cannot beat it. If you have no budget there are better out there. But once you get better than this device you get into the 500 dollar + range. Which a lot of people aren't wanting to pay for their home studio.

This product really makes your vocals sound warm as well as the acoustic guitar. Also if you own a guitar port you can plug into this with your guitar and then into the guitarport. That allows the amp models on there to sound a lot better having the tube pre amp in front of it.

But I mostly use it into an m-audio fast track pro. If this product tore up I would buy it again the same day. I do wish it had an on/off switch but that's not going to cause me to not have something that has this kind of sound because of a switch. Also it makes no difference to me what kinda adapter it plugs up with. That doesn't affect me in the least.

I have purchased one of the Bluetube and I think it was the great mistake - only one 12AX7 tube on two direct channel gives the noise on 50-60Hz. If you need recording distored sound without drive pedal - I think this item for you.

The Best for Less!

God I love this thing. I used it for my acoustic guitar and microphones, but now I run my electric guitar through it and into my Line 6 75 watt amp, and it sounds sweet. Like an old school tube amp. I can't say enough about this product. It's awesome.

If by warmth you mean muddy this is for you.

First of all, the "tube" that has the red diode under it to make you dumb enough to believe the tube is on is just plain deception. 2nd, it couldn't be true stereo preamp if both channels went through one tube. 3rd this thing will muddy up your sound really well. It is o.k. for taking the edge off of say an acoustic guitar, say for live performance purposes. It gives an o.k. effect to bass guitar...if you want that muddy overdrive sound. I paid half the current price for this and wouldn't pay a dime more. Oh yeah and the light in one of the VU meters went out about 4 months after I had it. (might've been able to prolong it's life if it had an on/off switch) This is a rip off for this "preamp".
