Classic "Tunable" Vintage Sound with Modern Sonic Fidelity

The ME-1NV is a single channel mic preamp that is designed to take the classic sound of the all-time studio-standard 1073 preamp and bring it to a new level of modern sonic fiedelity. Does it meet its design goals? Absolutely, with accuracy, transparency and vintage "tunable" sound! The circuitry allows for brilliant transformer saturation or the soft distortions of a single-ended amplifier. Extreme pushing of the unit will augment the sound of electric guitars, sound modules, and drums to add vitality, presence, and real punch.

Vintage Sound

The Great River ME-1NV features iron in the signal path for that big vintage sound. Its no-latency output monitoring provides a buffered sound feed to your DAW workstation. The ME-1NV's hi-Z input is ideal to shape the sound for bass, electric guitar, and sound modules. Dual metering provides visual monitoring of gain staging. The ultra-quiet noise floor delivers "stealth" performance for rich, textured vocal sounds. The Great River MP-2NV is a stereo version of the ME-1NV that will add an enhanced image to your recordings. The Great River ME-1NV also has a full +70dB of input gain so you can take that prized ribbon mic out of the cabinet for a rich, creamy sound with all the detail and no muddiness.

Here's the bottom line. The Great River ME-1NV is a golden channel priced for the project studio and equally at home in a world class facility. This preamp has the ability to enhance the sound of high-end mics as well as being able to make inexpensive mics sound better. Just place your trusty SM57 in front of your guitar amp and run it through the ME-1NV, and you'll hear what we mean.

Great River pre

Sweetest thing I've ever heard. Didn't expect to pad my mic just to be able to drive it more. But once i did, heaven

This pre amp is unbelievable! It sounds amazing and has so many options. Whether you want a crisp clear recording or some colorization this is the perfect preamp. Well worth the money! Would highly suggest it to any recording engineer!

the finest mic pre in this price, period

It doesn't matter what mic you plug into this unit, it will sound much better. The ME-1NV has been an absolute pleasure to own, and frankly, worth every penny. Vocals seat much better, and my home studio projects capture magic that was missing before I owned a Great River. If I were an engineer, I'm sure I could quote all the technical reasons why this sounds so great. However, as a mere home recording enthusiast, I'll simply tell you that I never believed a mic pre could make such a positive difference until I started using my Great River.

what a difference

I had only used the pre's in my Mackie 32/8 board and thought they sounded fine untill I bought this GR unit. and after working with this for a few months I will never go back to using crappy pre's again. The vocs are full and in your face, it makes everything now clear and stand out so much more in the finial mix. Its such a noticeable difference.

Simply Fantastic

This is my first peice of Class A equipment and there is such a huge difference in sonic quality. The fact that I am able to choose between transformers in the HI Z and XLR input. Then switching between 600 ohms for a very colored sound or balancing it out with the 300 ohm switch for a more even sound is amazing. I ALWAYS get tonal exellence out of this peice and it has also inspired me to start building my own Class A equipment which I am doing (1176 LN).I also have a friend that favors the sound of my GR me-1nv to his vintech x73-I. That sais alot. Vital peice of gear in my studio. if you have 1100 bucks and are contemplating what pre to get stop wondering because you are in for a treat of sonic cream pie. :) Derrick @

Sweetwater Advice

David Snyder

I have achieved a whole new level of professionalism in my home studio since I started using the Great River ME-1NV. I've worked with some pretty high-end singers, and they expect great-sounding vocals. With Class-A iron inside, and a simple but comprehensive set of controls outside, this is the vintage sound I've always looked for. I love being able to adjust both the front end and output level to hit my DAW at just the right saturation, and man, is it quiet! Nothing but pure tone, that even rivals the Neve 1073's I used to rent!
