Overview

The Fishman Fluence Open Core Classic 6-string Humbucker (Bridge, White) represents a modern approach to guitar electronics. Unlike traditional wire-wound pickups, Fluence pickups use stacked printed coils to eliminate noise and interference issues common in passive designs. This specific model, identified by the product code PRF-COC-BW1, features an 'Open Core' aesthetic, allowing the internal bobbins to be visible, which is a departure from the solid plastic covers found on other Fluence models.

Voice Architecture

The primary feature of the Open Core Classic is its three-voice versatility, selectable via a guitar's push-pull potentiometer:

  • Voice 1 (Vintage PAF): Calibrated to replicate the classic bridge humbucker response of the 1950s, offering a vintage output level with clarity.
  • Voice 2 (Hot-Rodded Humbucker): Delivers a higher output, modern humbucker tone suitable for aggressive styles without the typical 'baggage' or muddiness associated with high-gain passive pickups.
  • Voice 3 (Slightly Overwound Single-Coil): Provides a clear, punchy single-coil tone with sufficient output to remain balanced with the humbucking modes.

Performance and Efficiency

As an active pickup system, the PRF-COC-BW1 requires a power source, typically a 9V battery or an optional rechargeable battery pack. It is designed for high efficiency, providing up to 200 hours of continuous use. The active circuitry ensures that the tone remains consistent across various volume levels, avoiding the high-end loss often experienced when rolling down the volume on passive guitar circuits.

Comparison to Alternatives

While traditional strings such as the Ernie Ball M-Steel or Tim Henson Signature sets define the physical vibration of the instrument, the Fishman Fluence system defines the electronic translation of that vibration. Compared to standard passive humbuckers, the Fluence offers lower noise floors and a wider frequency response. Its multi-voice capability replaces the need for complex coil-splitting modifications that can often lead to volume drops or thin, weak tones.
