Overview

The Fishman Fluence Open Core Classic set is a sophisticated electronic upgrade for 7-string electric guitars. Unlike traditional wire-wound pickups, these units use Fishman's proprietary Fluence Core technology, which eliminates the noise, hum, and inductance issues typically associated with standard humbuckers. The 'Open Core' aesthetic provides the classic look of a standard uncovered humbucker while housing advanced active circuitry that allows for multiple tonal profiles within a single set.

Triple-Voice Neck Pickup

The neck pickup in this set is engineered for versatility, offering three distinct switchable modes:

  • Voice 1 (Vintage P.A.F.): Focuses on a classic vintage-style tone with balanced dynamics and output levels.
  • Voice 2 (Clear, Airy Chime): Provides a unique Fluence-exclusive tone characterised by extended high-frequency response and tight, controlled low frequencies.
  • Voice 3 (Clear Single Coil): Emulates an authentic vintage single-coil sound while maintaining high output, suitable for blues and clean rhythm parts.

Triple-Voice Bridge Pickup

The bridge pickup is calibrated to handle both classic rock and modern high-gain requirements:

  • Voice 1 (Vintage P.A.F.): A perfectly calibrated bridge humbucker tone with classic output characteristics.
  • Voice 2 (Hot-Rodded): A high-output bridge tone designed for lead playing and heavy genres, providing increased gain without the 'baggage' of traditional overwound pickups.
  • Voice 3 (Slightly Overwound Single Coil): A punchy single-coil voice that offers more bite than the neck position's single-coil mode.

Installation and Operation

The set is typically sold with the necessary components for installation, including a push-pull potentiometer. This pot allows the player to toggle between the different voices on the fly. As an active system, the pickups require a power source, usually a 9V battery or an optional Fishman rechargeable battery pack. The black 'Open Core' finish ensures the pickups fit the aesthetic of modern and traditional 7-string instruments.

Comparison to Alternatives

While traditional 7-string humbuckers from brands like Ernie Ball or D'Addario-related hardware focus on a single magnetic profile, the Fluence system offers three. Compared to standard active pickups that are often criticised for being 'compressed,' the Open Core Classic set is designed to maintain the dynamic feel of passive pickups while offering the clarity and silent operation of active electronics.
