Founded by Nick Greer in 1998, Greer Amps is a boutique pedal and amplifier company based in Athens, Georgia. Greer started building pedals out of necessity after experiencing equipment failures, assembling his first single-transistor drive circuit from RadioShack parts. Word of mouth turned a hobby into a business, and Greer Amps has been hand-building effects pedals and amplifiers one at a time ever since. Every pedal is hand-wired with true bypass switching and backed by a lifetime warranty to the original owner.

The company's lineup spans overdrive, boost, fuzz, compressor, and tremolo pedals, alongside a small range of amplifiers. The Lightspeed Organic Overdrive is their signature pedal and the product that helped establish the brand's reputation — a transparent, touch-sensitive overdrive prized for its natural feel and harmonic richness. Other notable pedals include the Southland Harmonic Overdrive, Super Hornet octave fuzz, SOMA 63 Vintage Preamp, Special Request single-knob boost, Tomahawk Deluxe Drive, and Black Mountain Crunch Drive.

Greer Amps pedals have found their way onto the boards of a wide range of professional musicians, including Jason Isbell and the 400 Unit, Dweezil Zappa, Devin Townsend, Modest Mouse, Ariel Posen, Charlie Starr of Blackberry Smoke, Coy Bowles of Zac Brown Band, and many Nashville session players and touring guitarists. The company employs a small team of builders in Athens who assemble and test each unit by hand before it ships.

Greer Amps has 36 products cataloged on Equipboard, including Overdrive Effects Pedals, Boost Effects Pedals, and Fuzz Effects Pedals. Their gear is featured by 55 artists, with the strongest followings in Rock, Folk, World, & Country, and Blues. Notable users include Jordan Smith, Dweezil Zappa, and Eric Cannata. Greer Amps's catalog spans the full price spectrum — from entry-level options to high-end flagships.
