The Grand Symphony Builders Edition has Taylor V-Class Bracing, which results in higher volume, longer sustain and improved intonation. Koa back and sides give the guitar powerful bass, warm mids and brilliance in the highs. Together with the short scale, the Koa top supports its dynamic range. The Soundport Cutaway creates a spatial, reverb-like effect. Taylor's own active ES2 dynamic piezo system with bass, treble and volume controls is used as the pickup.
