Independent shopping perspective

The Korena take

Designed around a Grand Performance cutaway body, this Custom Shop acoustic brings together a spruce top and mahogany back and sides. The forward-shifted scalloped X bracing supports quick response, punchy attack, and even output across the strings, while mahogany adds warmth, focused midrange, and tight lows. Its modified low oval mahogany neck, satin finish, and ebony fingerboard support smooth movement. Grover nickel vintage-button tuners and a compensated bone saddle complete a stable, performance-oriented setup.
