the Surf Spring is crafted entirely by just one guy in France! Inspired by Fender signature’s blend of spring reverb with tremolo from their iconic Blackface amp circuitry.

Rooted in the legacy of the Vibroverb one of the earliest Blackface amplifier designs, the first ever to feature a built-in spring reverb and a tremolo (misccalled vibrato at the time). The Surf Spring is a convenient solution to access Fender Blackface magic on any amp. Ideal for pairing with amps lacking of a built-in reverb, it’s your ticket to surf rock & blues rock guitar tones, no pedalboard required !
