The latest addition to the Flynn Amps range of guitar booster pedals is the all new FET booster. Unlike Flynn Amps Classic OC44 and Rory Gallagher >Hawk pedals this booster features a unique new design. The FET booster preserves your guitar tone while providing loads of pure clean boost with just a touch of FET shimmer and detail. Many modern valve amps can suffer from lifeless clean channels and the FET booster can really invigorate these amps and bring your guitar tone to life.
