Fishman’s Fluence Classic and Modern humbuckers are fully analog active pickups combined with Fluence Core printed “coils.” Each has selectable voices and are designed to eliminate battery cost and implementation thanks to a rechargeable Lithium-ion battery pack that plugs in via USB connection and offers 200 hours of playing time. A standard 9V battery can also power Fluence pickups. Go to www.fishman.com.
