B·45 - Masterbuilt 5-string bass guitar with Italian Olive top

Overview

The Masterbuilt 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 Essential Series design, and bridge the gap between E & Signature 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 Masterbuilt 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

Masterbuilt 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.

• Vēa

The Vēa shape evolves the Precision-style bass into a form that’s more balanced, comfortable, and structurally refined.
Its symmetrical, non-offset design offers improved ergonomics and weight distribution, uniting classic authority with modern playability.

• Number of strings : 5

Expanded-range bass adding a low B string. Increases versatility and extended low-end access while maintaining familiar 4-string playability with a slightly wider neck.

• Scale Length : Standard 34"

The industry-standard bass scale length. Offers a balanced feel between string tension, playability, and clarity. Ideal for versatile playing styles and compatible with most bass string sets.

• Number of frets : 24

Extended-range configuration offering two full octaves per string. Ideal for soloing, technical playing, and modern styles requiring upper-register access.

• Neck Profile : S

Slim, fast neck shape with reduced thickness. Optimized for speed, smaller hands, or players seeking maximum comfort and agility

• Radius : Modern 12" to 16"

Flatter fretboard radius for fast playing, low action, and effortless bending. Ideal for technical and contemporary playing styles.

• Body : Roasted Red Alder (Alnus rubra - France)

Roasted Alder benefits from heat treatment, improving its structural stability and moisture resistance. The process darkens its color naturally while slightly reducing weight. Roasted Alder has a very uniform response to vibration, with quicker resonance and enhanced durability, making it ideal for stable instruments in variable climates.

• Neck : Norwegian Roasted Maple (Acer platanoides - Norway)

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 : Norwegian Roasted Maple (Acer platanoides - Norway)

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.
