Overview
The M-Series is the mid range Series of Belforti's line up. These instruments represent the entry in the world of fine lutherie, with decorative tops, high performance woods and electronics, in a form factor that represents modern lutherie. They are a continuity of the E-Series design, and bridge the gap between E & S-Series.
As a part of this Series, this instrument features the following :
Master Grade Tonewoods
The Master-grade woods that are known for their stunning visual appeal as well as their tonal excellence. These aren't just any pieces of timber; they are carefully selected for their aesthetic beauty, tonal richness, and resonance.
All the Master Grade woods are rated between 81 and 90 on the Belforti rating.
Faux Pickguard Aesthetics
The faux pickguard gives the M-Series their distinctive look. It maintains this classic look and brings coherence to the design, while preserving the grain pattern. It is made out of inlayed ebony.
We could never put a piece of plastic on these, not even transparent acrylic !
Matching Premium Inlays
M-Series fretboard and headstock inlays are exclusively made out of the top wood you chose. They are extracted from the scraps of your top, and they are outline with a black inlayed ebony outline.

Body : Flamed Ash
Roasted Swamp Ash combines the lightweight and vibrant resonance of traditional swamp ash with increased stability and reduced moisture content from the roasting process. It offers enhanced structural integrity, excellent vibration response, and beautiful caramelized hues, making it both functional and visually striking.
Neck : Flamed Norwegian Maple
Roasted Maple undergoes a heat-treatment process that reduces moisture content, increasing dimensional stability and resistance to environmental changes. It’s lighter than regular maple, with improved stiffness and a rich caramel color. Its reduced internal stress makes it highly resistant to warping, ideal for touring instruments or varying climates.
Fretboard : Flamed Norwegian Maple
Roasted Flamed Maple combines the dramatic visual appeal of flame figuring with the structural benefits of thermal treatment. It offers excellent dimensional stability, lower moisture absorption, and a silky smooth playing surface. The roasted process enhances the contrast of the figuring for an even more luxurious appearance.

Waterfall Bubinga
Bubinga (Guibourtia spp.) is a dense hardwood native to Central and West Africa, known for its rich reddish-brown color and striking waterfall figuring, where the grain forms flowing, wavy patterns. This natural effect creates a sense of depth and movement, enhanced by the wood’s natural luster. The grain is typically fine and interlocked, giving it both durability and a smooth finish. Highly valued for its visual complexity and strength, waterfall bubinga is a sought-after choice for decorative and high-end woodworking applications.
Lovely Curves
Signature Series tops are not only bent on the armrest which keeps intact the beautiful grain, but they are also inlayed, which seamlessly integrates the top to the body.
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 S-Series philosophy: maximum output without distortion, and emotion without compromise.
