Emmergy FX is a boutique guitar effects pedal builder based in Bridgwater, UK, founded by Michael Gardner. The company hand-builds a range of pedals for guitar, bass, and synth, with circuits soldered point-to-point and finished with custom artwork. Each unit is built to order in a small workshop and backed by a lifetime repair-or-replace policy.

The lineup leans heavily into fuzz, distortion, delay, and modulation, with releases such as the Slowdriver four-transistor shoegaze fuzz/distortion, the Later and Later delay/overdrive, the Mirror Mirror dual delay, the Empty Skies oscillating fuzz, the Gristle Throbber modulator, the Dial-Up Filter Fuzz, and the Phosphocreatine overdrive. Many pedals are produced in small batches or as one-off custom builds to player specification.

The brand has a particular following in the shoegaze community. The Slowdriver was developed in collaboration with Christian Savill of Slowdive, and Emmergy FX pedals have been associated with members of that band. The company also makes appearances at UK pedal events such as the Bristol Pedal Show and FX Expo.

Emmergy FX has 2 products cataloged on Equipboard, including Distortion Effects Pedals and Delay Effects Pedals. Their gear is featured by 2 artists, with the strongest followings in Rock and Pop. Notable users include Neil Halstead and Christian Savill.
