Great River Electronics is a professional audio manufacturer based in South Saint Paul, Minnesota, along the Upper Mississippi River. The company was co-founded by designer Dan Kennedy and his partner Dennis Pfab, with the initial microphone preamplifier designs growing out of Kennedy's work solving noise issues in orchestral recording with ribbon microphones. An early contract to build custom mixers for CBS Radio helped the operation scale up from a basement workshop into an established pro-audio brand.

The company is best known for its hand-built microphone preamplifiers and equalizers, offered in two design families: the original MP series, which is voiced for a clean, fast, transparent sound, and the NV series, which draws on vintage British console circuitry for a thicker, more colored tone. Core products include the MP-2NV and ME-1NV dual- and single-channel preamps, the MP-500NV 500-series module, and the EQ-1NV and EQ-2NV program equalizers.

Great River gear is a staple in commercial tracking and mastering rooms, often cited for its use on drums, bass DI, electric guitar, and vocals where engineers want either pristine headroom (MP series) or a punchy, saturated character (NV series).

Great River has 14 products cataloged on Equipboard, including Effects Processors, Preamps, and Mixers. Their gear is featured by 15 artists, with the strongest followings in Rock, Electronic, and Pop. Notable users include Anthony Marinelli, Kevin Parker, and Deryck Whibley.
