Fishman Fluence Multi Voice Pick Up Classic Humbucker Bridge (Nickel). The electric guitar pickup has been wound since 1934. 80 years later, Fishman have unwound it. The Fluence from Fishman is original and totally re-invented not to mention being free from the hum, noise and frustrating inductance issues that plague even the most coveted wire-wound pickups. This cleaner sound reveals pure, uncorrupted and musical tone.
