All the musicality of Alnico. Full chords and fluid solos, plus a voice you've never heard in a humbucker. Great in both positions, or commonly paired w/Ceramic bridge. We all love the sound of vintage pickups. That being said, buzz and inductance issues leave a bit to be desired. With Fishman Fluence Modern Alnico pickups, you can run hundreds of feet of guitar cable without any quality loss. Your volume control will operate with unprecedented smoothness, allowing you to milk useful sounds out of your guitar, even at low settings. To call these pickups "noiseless" would be a grand understatement! Multi-voice Fluence Modern Alnico pickup provides two distinct voices The Fluence Modern provides you with the choice of two unique, selectable voices. The Fluence Modern Humbucker Alnico pickup's first voice is reminiscent of a modern active pickup. Plug into your amp and treat yourself to that familiar modern active pickup with a full, boosted sound and killer articulation and dynamics. The second voice is an exclusive Fluence sound with a clean, crisp, and fluid tone without any mush. Don't worry, both voices deliver the unmistakable humbucker sound! The voices can be accessed by any number of standard switches or push/pull controls and can be added as a completely reversible modification to most guitars. Power supply delivers 200+ hours of use Offering 200+ hours of playing time, Fishman Fluence Modern Alnico pickups also fully recharge in a matter of a few hours by using a standard USB charger. These pickups utilize either a standard 9V battery, or you can use the optional Fluence battery pack. These battery packs screw onto your guitar in place of the control or spring cover, requiring no modifications to your instrument.
