Nexus Low Frequency Contour System

A physics-driven approach to low-end clarity and stability in extended-range instruments, designed to deliver tighter feel, better definition, and controlled low-frequency response.

The Nexus Low Frequency Contour System (LFC) was developed to address one of the most common challenges in modern extended-range instruments: maintaining clarity, stability, and definition in added low strings—especially on 7- and 8-string designs.

Low strings naturally tend to feel and sound loose. Increasing string gauge often leads to a darker, less articulate tone, which can become uncomfortable during performance and even more problematic in recording environments.

The LFC System is based on well-established principles of physics, with a key role played by the Helmholtz law of energy conservation in mechanical systems. In this context, two forms of energy are essential: potential energy and kinetic energy (historically referred to as vis viva and tension energy).

Within the LFC System, potential energy is stored in precisely actuated brass pipes and solid brass blocks integrated beneath the pickups, while the strings themselves act as carriers of kinetic energy.

By carefully controlling the transfer and balance of energy within the closed system of the instrument, the Nexus LFC System significantly enhances the definition of low-frequency response. The result is a tighter feel, improved note separation, and a more selective, controlled low end—without sacrificing musicality or dynamic range.
