The Great River MP-500NV is a high-end 500-series microphone preamp designed to capture the vintage tone of early ’70s consoles while delivering modern clarity, punch, and performance. Featuring flexible gain staging with metering before and after key stages, it allows for everything from clean amplification to rich, driven character. Compatible with dynamic, condenser, and ribbon mics, it also includes a dedicated Hi-Z DI input for instruments. Built with the same circuitry as the NV series, the MP-500NV offers classic analog sound in a compact 2-slot 500-series format.

There are some minor scratches but unit is fully functional.
