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 !

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 : 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.
