This is a fantastic pre amp. I purchased it to replace a usb interface that was not supplying enough power to the mic, even though it has 48v phantom power switch. I could not believe the sound of this pre, especially when the tube is engaged. I use it primarily for voice over work. The sound is awesome: warm, clear, beautiful. I cannot believe the difference.

It is truly feature rich. Most of which I will never use but you might. Fist off it has two channels. You can run the pre amp in tube mode or solid state. Also, it has mirror controls for both, with very nice pots that are responsive to your every adjustment. It has an 80Hz filter switch, some great VU meters to monitor your signal, 48v phantom power switches, as well as a -20 pad.

Could not be easier to use. Simply plug in your mic or instrument and away you go!

Very well built, good looking unit. I don't know if this pre would be good for the road as I do not use it for that purpose. However, it is small enough that you could probably take it with you on the road with no problems.

Tremendous bang for the buck! This does the job of a $500-$750 pre amp, it is that good! The tube which it came with sound fantastic, so I can only imagine what it would sound like with a different tube.

I would replace it in a second if was to get stolen.

This preamp does what it's supposed to do; however, in order to get just the right amount of texture for the work I do (audio books), I have to turn up the tube drive a little over 50% and the gain to nearly 100%. The other issue I noticed is that the VU meters don't move at all. I know that they work, but I have to kiss the mic (Heil PR 40) and yell into it. The sound I produce obviously becomes over-modulated, and makes for a terrible recording, but at least I know that the meter is not broken.

The most useful feature for me are the gain and the tube drive. I have read a lot of discussion about upgrading the tube. Perhaps this is something I'll be doing in the near future. This preamp absolute needs an on/off switch. Disconnecting and reconnecting the power cord all the time is silly. This is the 21st Century, for cryin' out loud.

There's not much to using it: Take it out of the box, plug it into the wall, set the levels the way you like and you're in business. But it really needs an on/off switch. What's up with that?

I've only had it a month, but it seems to be holding up. I like the fact that the case is metal and not plastic. The jury is still out on the issue of quality. I'll have to wait and see if it lasts beyond the life of the warranty.

This is a very low-cost way to get into the mic preamp "business," and for what I do it does the job. I think that if I were getting paid for the audio books I record, I'd be willing to shell out the big bucks.

I haven't had to call for service.

This mic preamp looks cool because of the VU meters. I really believe that is its best selling point. But in reality, it's just an economical tube mic preamp that's priced just about right for the market.

I haven't used any high-end gear, but I assume most studio recordings I listen to use pretty posh stuff, and this unit is definitely comparable. honestly, there are units for 3,000 so what can you really expect. the noise issues people talk about are probably due to bad engineering rather than a high noise floor. I use the crumiest setup: mxl - bluetube - laptop 1/8" line input, and the hiss is not distracting at all. like other people have said, you just need to watch your gain levels and make sure not to dial in too much tube

nothing special... everything works as advertised

pretty simple, just plug it in and record

seems to be built well: metal encasement, solid feeling. the knobs do seem a little cheap though

like I said earlier, for low

never dealt with them

WOW ! Very suprised. I bought this unit only to give me 2 additional channels for tom tom micking. It ended up being my best sounding preamp for everything (espacially vocals). This is a real preamp. It sounds better than many other preamps in the $700-$1000 range. The trick : don't use the tubes that much. Simply turn the knob so that it engages the tubes, but don't get into overdrive. That way you'll get a perfect and pro sound. Sounds amazing with the 414-ULS and all dynamic mics. Now I understand wy some people use the SM57 for vocals... it's all in the preamp.

I use the tube knob almost like an EQ. It adds mid for those thin sounding mics. But don't over use it with your good mics.

Yep!

Solide.

It's worth a lot more. Prbably around $600. Makes me want to try the MP20... can't imagine the sound quality of that unit.

No trouble yet.

Yeah.

Don't care for the noise of the device added to the signal. A little too much noise for a $200 device.

I thought the tube addition would be nice but I just don't like it. I wanted this for warmth on an electric guitar, recording direct. 'Just don't like it.

No problems here, but maybe I'm not using it right. I've played around with it, and just haven't found the right noise to signal ratio that sounds good. Too weak of an amplified signal.

Construction is fine.

I don't recommend it. Save your money and buy a real pre amp that amplifies the signal to a greater degree and doesn't add noise to the signal.

Haven't used it.

A VERY NICE SOUNDING 12AX7 TUBE PREAMP. IT IS CLASS A AND HAS A WARMTH THAT WILL ADD NICE ANALOG CHARACTER TO VOCALS AND ACOUSTIC GUITAR. I LIKE THE SOUND ALOT BETTER THAN THE SINGLE CHANNEL TUBE PRE BY PRESONUS. THAT PREAMP UTILIZES A DIFFERNT TUBE AND DOESN'T HAVE AS NICE A WARMTH. FOR THE MONEY THIS PREAMP IS WORTH EVERY PENNY.
