The Fishman Fluence Custom Matt Heafy 6-String Humbucker Set has been designed for pure tonal excellence. Add an iconic sound to your performance with these models that have been designed with heavy metal in mind due to their designer Matt Heafy. The guitarist of the band Trivium wanted to create a set that reduces the “amount of stuff between fingers and the listeners ears”. Each pickup has been designed with three different voicings for a wide range of tonal possibilities. The neck provides a full and boosted tone with articulation a clean humbucker tone without the thin and plinky sound or a glassy and crystal-clear tone. The bridge offers the ideal ceramic humbucker tone with a crisp crunch and tight bass an organic output alongside distortion characteristics and response or a clear and bright tone. Enhance your performance with these powerful pickups.
