Nick Jennison reviews the Taylor AD12e-SB—as it continues the US brand's American Dream Series tradition of high-performance, US-made, all-solid-wood acoustic guitars that match great tone with an accessible price. This compact Grand Concert fits the bill with walnut back and sides, a spruce top and V-Class interior bracing—culminating in a warm, woody sound with bold volume, blooming sustain and a low-end response that will grow richer over time as the wood matures.
