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.

Features
  • Stereo microphone/instrument preamp
  • Dual Class A gain stages
  • Tube drive from 12AX7 tube
  • Neutrik XLR and 1/4" High-Z combo input connectors
  • Neutrik balanced XLR/TS 1/4" outputs
  • 20dB pad, polarity reversal, and 80Hz filter on each channel

If you need a great-sounding and versatile preamp for your home or project studio, the BLUETUBE fits the bill. Order yours now!

      This is a great deal for the money. Preamps are usually put in the 'you get what you pay for' category but I think this unit is exceptional. Run a decent mic through this and maybe a vocal enhancer and you couldn't ask for better vocals given the money spent. I use a Shure SM7B and an Antares AVP-1 vocal producer with this unit and absolutely love the results. It's the perfect thing to add that warmth I'm looking for in my vocals.And in response to all those comments regarding the lack of a power switch, some of the best rack-mounted equipment are designed to be left on. But if you are all so worried about it, instead of sabotaging the products overall review, why don't you use your brains and go to the nearest office supply store and buy a power strip with a switch on it??? That way you can plug multiple devices in and turn them all on and off with ONE simple switch. Thinking is fun!

      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".

        Comments about PreSonus BLUETUBE DP Stereo Dual Path Microphone/Instrument Preamp with 12AX7 Tube:

        The Blue Tube changed everything for me. What I formerly thought was a clean recording I now know as poor. I can hear detail I didn't know possible. I can hear the differences in my microphones and through trial can tell what applications they are best suited for. You don't know what you don't know, and I'm glad I followed advice on Tweakheadz website and bought my first real pre-amp. This new found clarity in mic-ed recording has led to discovery and improvement in all of my recording practices and techniques. If you are using pre-amps costing less than a Benjamin, then you haven't really heard your microphones yet.

        The tube feature is to be used cautiously at first until an understanding of its sensitivity is learned. Its effects can be heard just a few clicks in past "on". It can add significant transformation to tone, as well as gentle warmth at low levels.

        I had to pad some of my microphones for the first time, the Bluetube revealled their signal strength that was previously unknown to me. This thing adds the juice without adding noise. My ears and eyes have been opened, my enthusiasm for recording peaked, like the signals I now get.

          A good device and my church's music connoisseurs even took notice of the "rounded" and "thick" tones from my Gibson ES339 coming through the church's antiquated sound system.

          Highly recommended for any guitar player.

          Comments about PreSonus BLUETUBE DP Stereo Dual Path Microphone/Instrument Preamp with 12AX7 Tube:

          While this may be of value to those who don't have a lot of recording equipment. Since I am blessed with a great deal of high dollar mics, vocalist effects, quality recording devise, at this point I've not found it to be of any help. For me it was a bad investment, but that doesn't mean the same goes for everyone. I'm still trying to hear any thing that sounds better when using it. If you don't have a distortion pedal it does add some crunch to a guitar. This review is based on my experience, and is not meant to contradict any other review.

          Tremendously Good Deal

          By SpecGrav

          Comments about PreSonus BLUETUBE DP Stereo Dual Path Microphone/Instrument Preamp with 12AX7 Tube:

          This is just the thing to add some warmth, whether it's to vocals, a direct or mic'd acoustic, or direct bass or guitar. I REALLY wish there was a power switch and that it had front access to the jacks, but it's a small price to pay for the warmth and clarity this gives you with no fuss. I've been recording for 15+ years, and I have to agree with the 'no better gear for the money' attitude in the other reviews.

          Doesn't work? Don't write a review

          By Sonny D

          Comments about PreSonus BLUETUBE DP Stereo Dual Path Microphone/Instrument Preamp with 12AX7 Tube:

          Until you have used this product it is rediculous to write a review. All brands have defective products no company is immune to this. I have a working ubnit, however the first one I received had a defective channel. Rather than act like a child who got a broken toy on Christams I returned it and got a working one. You absolutely can not get a better tube pre for this price. It gives my vocals a warmth and depth I have only heard when in the studio, I record my vocals at home in the bathroom. When I plug my guitar in it even makes my practice amo sound great running direct in. It's easy to use and use it I do, it has not been disconnected frrom my BR 1200-CD since I hooked it up. Great Buy!!!

          not good

          Comments about PreSonus BLUETUBE DP Stereo Dual Path Microphone/Instrument Preamp with 12AX7 Tube:

          Just got this Presonus Bluetube DP yesterday. I began experimenting by putting it between my guitar and DAW to try to add a bit of warmth to the amp modeling software. The VU meter went into the red when I strummed a chord assertively with the gain on the Bluetube at zero. The 20db pad did nothing. The tube drive knob did nothing. Both channels were equally defective. I'll be returning it at once.

          Comments about PreSonus BLUETUBE DP Stereo Dual Path Microphone/Instrument Preamp with 12AX7 Tube:

          I really like this and it does what it says it does. An on-off switch would be nice but they are quite easy to install. For those earlier posts wondering about stereo from only one tube... a 12AX7 tube has two "sides" in it, not only one.

          Bluetube + Firepod

          By Presonus_Fan

          from Virginia

          Comments about PreSonus BLUETUBE DP Stereo Dual Path Microphone/Instrument Preamp with 12AX7 Tube:

          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

          By Rats11444

          from New York City, NY

          Comments about PreSonus BLUETUBE DP Stereo Dual Path Microphone/Instrument Preamp with 12AX7 Tube:

          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.
