Flynn Amps is a boutique amplifier and effects builder based in Glasgow, Scotland, operating out of a workshop under the historic railway arches in the Tradeston district. The company hand-builds all-tube, point-to-point wired amplifiers drawing on classic vintage circuits, including Tweed-style Champ, Deluxe, Super, Pro, Twin and Bassman models, as well as a Deluxe Reverb and a British Plexi variant. Alongside its amplifier line, Flynn also winds guitar pickups and serves as one of Scotland's primary service and repair centers for musical electronics.

The pedal range is small and focused on vintage-style gain and boost circuits. It includes the Classic OC44 Booster, a recreation of the 1960s Dallas Rangemaster treble booster built with vintage transistors; the FET Booster, a high-impedance clean boost; a germanium-style Fuzz Tone; and the Rory Gallagher Hawk, a booster modeled on the tone of the Irish blues-rock guitarist. The pedals are housed in custom metal enclosures with tool-free battery access, Switchcraft jacks, Alps potentiometers and true-bypass switching.

Flynn Amps has 2 products cataloged on Equipboard, including Boost Effects Pedals. Their gear is featured by 5 artists, with the strongest followings in Rock, Blues, and Folk, World, & Country. Notable users include Rory Gallagher, Captain Sensible, and Davy Knowles.
