Looking to part ways with a PAIR (2 Mono) of Great River MP-500NV preamps. This preamp is an amazing offering for many sources, including bass guitar, drums, guitars, and vocals, plus many more that I haven't tried! I'm selling the pair only because I already have the 19" racked version and decided to downsize.

The preamp includes several features known to the Great River - Phantom Power, Impedance, Loading, Polarity, Input Gain up to 60dB in 5 dB Increments, Input and Output Metering, Hi Z (1/4") Instrument Input, and Output from 0 to -10dBv.

As noted, the preamp pair is technically used, although only 3 months old (purchased May 2017) and there are slight marks from the mounting screws, which is normal the moment the unit is mounted. However beyond that, I cannot find anything wrong with either preamp. I always wash my hands when operating my equipment, so you won't find any greasy finger prints. Also, I don't smoke and the units were never in that environment - instead they lived in a low humidity, smoke-free, clean studio!

Again, this listing is for a pair of the MP-500NV Great River Preamp, with consecutive serial numbers. This probably should go without saying, but these two preamps require a 500 series rack for installation. Details of approved racks can be found at Great River's website.
Please note that these preamps are in extremely good condition. Free shipping is offered to Continental US 48 States Only. Original packaging is included.

From Great River:

MP-500NV Single Channel preamp module

The MP-500NV is a professional quality microphone preamplifier designed to re-create the vintage sound characteristics of the early 1970s large consoles. Modern components give the MP-500NV more clarity, punch and performance under normal use. In addition, features like metering before and after the major gain stages let the user drive it 'creatively' to greatly expand the range of sonic options. Any microphone will benefit from the power of the MP-500NV preamplifier, including dynamics, condensers and ribbon types. The MP-500NV uses the same audio and metering circuitry found in the NV series preamplifiers. This unit is designed to fit into a '500' series rack using 2 available slots. It receives its power supply from the host rack. The unit is equipped with a HI-Z instrument jack that has its own input amplifier and was designed for 'DI' applications. All specifications and performance details are identical to the NV series preamplifiers with the exception of size, weight, patch jack, -10dBv Out.

The MP-500NV has been tested and accepted into the VPR Alliance.
