Though you might see similarities to a Grand Auditorium, the GS is unique in both sound and shape. Significant changes in its geometry yield a deeper, more piano-like bass. A wider lower bout and higher, wider waist return ample volume and low-end sustain, in symphony with fuller mids and balanced highs.  Check out David Martin's audio file of this instrument and I think you'll agree (see link below).

   Using proprietary pickup technology developed at Taylor, the Expression System® amplifies your guitar with an unrivaled, natural live sound. Onboard tone controls provide added flavor, or set flat for an uncolored, exceptionally-clean amplified sound. 

   The finish used to create this guitar's lustrous gloss top, back, and sides was developed at Taylor for maximum durability and resistance to cold-checking. This ultra violet-cured finish is also more environmentally friendly than traditional lacquer finishes.
