The Guitar & Its Maker
Jeff Sigurdson — Canadian Craftsmanship Meets Modern Innovation
Canadian luthier Jeff Sigurdson has developed a distinctive approach to contemporary classical guitar making that brings together traditional woodworking, careful acoustic development, and modern construction techniques.
His instruments reflect a commitment to the relationship between the performer and the guitar, with particular attention to tonal balance, responsiveness, projection, and the expressive possibilities of carefully designed concert instruments.
While the classical guitar remains deeply connected to centuries of tradition, innovations such as double-top construction have introduced new opportunities for luthiers to explore the relationship between soundboard weight, stiffness, and acoustic efficiency.
Sigurdson’s work embraces these possibilities while maintaining an appreciation for the tonal warmth, musical colour, and refined craftsmanship associated with fine traditional instruments.
The N-633 — A Refined Double-Top Concert Guitar
Completed in November 2026, the N-633 illustrates this approach through an exceptional combination of materials and carefully considered design features.
Its AAAA-grade dark cedar double top incorporates a lightweight balsa inner core. This construction is intended to achieve an effective balance between structural support and soundboard responsiveness, allowing the maker to explore acoustic characteristics that differ from those of a conventional solid-wood soundboard.
The Madagascar rosewood back and sides provide a visually striking complement to the dark cedar soundboard. Inside the body, the sides are lined with maple, adding another distinctive element to the instrument’s construction.
The elevated Spanish cedar neck and ebony fingerboard with a 20th half-fret demonstrate a contemporary approach to playability, while the Indian rosewood armrest provides additional comfort for the guitarist’s right arm.
One of the instrument’s most interesting features is its soundport with an adjustable magnetic cover, secured using eight magnets. This component allows the guitarist to experiment with the soundport’s opening and its effect on the playing experience.
The decorative details are equally noteworthy. A beautifully figured spalted maple rosette provides an elegant visual focal point, complemented by the Indian rosewood bridge and headstock veneer.
Premium Gotoh 510 series machine heads with ebony knobs ensure precise tuning control, while the hand-rubbed French polish highlights the natural beauty of the woods and completes the instrument’s refined appearance.
Weighing approximately 1.65 kg, this concert guitar brings together thoughtful modern construction, elegant materials, and meticulous craftsmanship.
A Distinctive Canadian Concert Instrument
What makes Jeff Sigurdson’s approach especially interesting is the harmony between modern technical features and traditional artisanal character.
From the double cedar soundboard and elevated neck to the adjustable soundport and carefully selected decorative appointments, every element contributes to an instrument designed around the needs of the contemporary classical guitarist.
For musicians who appreciate modern innovation without sacrificing the elegance and craftsmanship of the traditional concert guitar, the opportunity to experience the N-633 firsthand provides valuable insight into Sigurdson’s work.
