Below is a breakdown of the key features that define the S-Series. Each element has been selected and refined to serve both the player and the instrument — from construction choices to electronic configurations.

Every Signature Series comes with our most advanced signature lutherie technique

The Curved Inlayed Top

Not only do you get the most rare Private Stock Tops, but instead of being glued on top of the body of the instrument, Signature Series tops are inlayed in the body, and outlined with a 3 ply purfling.

This creates a seamless integration of the top in the instrument's design, gives it a natural contoured binding look, and did we mention it still follows the curve of the armrest

Electronics

In the Signature Series, every circuit and component is chosen to serve one purpose — to capture the purest form of the instrument’s voice.

Each system delivers a wide dynamic range, low noise floor, and exceptional touch response, allowing the sound to remain open, articulate, and deeply expressive.


Whether it’s the focused energy of a guitar under gain or the enveloping presence of a bass in motion, the Signature electronics translate nuance into authority.

Transparent, powerful, and responsive, they embody the Signature Series philosophy:maximum output without distortion, and emotion without compromise.
