Sound Pure's Take

Representing the pinnacle of Canadian lutherie, the Boucher SG-173-GU Studio Goose S-Jumbo pairs Master Grade torrefied Adirondack spruce with striking 5A flamed koa back and sides. Weighing 4 lbs 8 oz, its large body leverages hand-scalloped forward-shifted X-bracing to produce immense projection, rich harmonic complexity, and crisp note separation. Equipped with the Gold and Ultimate appointment packages, it features Style-41 abalone purfling, an abalone rosette, and koa-bound ebony appointments with mother-of-pearl Crown inlays. The satin mahogany neck offers a 1.750" Tusq nut and 25.5" scale, while Gotoh Gold 510 tuners ensure flawless tuning. Signed internally, it includes a deluxe TKL tweed hardshell case.
