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.

Woods
Woods
Body : American Redwood
Redwood is a rare and exceptional choice for instrument bodies — a tonewood as distinctive in sound as it is in appearance. Lightweight and highly resonant, it sits in a tonal sweet spot between the warmth of mahogany and the clarity of alder, producing a rich, complex fundamental with excellent sustain and natural compression. Its deep amber-to-sienna coloring, straight grain, and silky surface texture make it one of the most visually striking tonewoods available, and one of the least commonly seen on a boutique build.
Neck : Birdseye Maple
Birdseye maple is one of the most sought-after tonewoods in boutique instrument building — prized equally for its visual character and its acoustic properties. The dense, tight grain delivers a fast, snappy attack with excellent note definition and long-term stability, resisting the seasonal movement that affects less consistent woods. No two birdseye pieces share the same figuring pattern, making every neck carved from it inherently unique.
Fretboard : Birdseye Maple
Harder and brighter-sounding than rosewood or ebony, maple fretboards contribute a crisp, defined tone with a smooth, fast playing surface that responds well to both light and aggressive technique. Birdseye maple adds a visual dimension that sets it apart from plain maple — its characteristic swirling eye-shaped figure catching light differently across every board. A classic choice for players who want clarity, precision, and a fretboard that ages beautifully with use.

Top
Birdseye Maple
Few tonewoods command attention the way birdseye maple does. Characterized by its dense concentration of small, swirling eye-shaped figures scattered across the surface, it is one of the rarest naturally occurring wood phenomena — the result of unusual grain distortion during growth, and impossible to cultivate or predict. No two tops are alike, and highly figured pieces are considered collector-grade material in their own right.
Acoustically, birdseye maple contributes brightness, sustain, and a tight low-end response that pairs well with warmer body woods beneath it. As a top, it adds definition and articulation to the overall voice of the instrument without overpowering the tonal character of the core. Under a clear finish, the figuring takes on a three-dimensional, almost liquid quality — shifting and shimmering as the light angle changes, making it as alive to the eye as the instrument is to the ear.
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.
Pickups
2 Delano Xtenders
Delano's Xtender series represents a reference point in boutique bass pickup design. The quad-coil architecture delivers full, even response across the string range with virtually no hum, while retaining the organic character and punch that passive-voiced pickups are known for. Wide dynamic range, exceptional clarity, and a natural sensitivity to playing nuance make the Xtenders a trusted choice among professional players and custom instrument builders alike.
Circuit
Preamp
Glockenklang 3 Band
Designed and manufactured in Germany, the Glockenklang 3-band preamp is widely regarded as one of the benchmark active electronics solutions in high-end bass building. Its wide yet musical EQ range enhances rather than colors the natural voice of the instrument, with bass, mid, and treble controls that respond with exceptional transparency. Clean, quiet, and precise — it preserves the fundamental character of the pickups and tonewoods it works with, rather than imposing a sound of its own.
