Spoon Phillips visited Maury's Music for another round of demo videos. After we finished all the single guitar videos, we carefully compared the Sitka-topped BR-183 to the Adirondack-topped BR-183A. Which one do you prefer & why? Post your comments below. The BR-183 has a Sitka spruce top, 1 11/16" nut and decorated headstock. The BR-183A has an Adirondack spruce top, slightly wider 1 3/4" nut, and a more understated headstock design. Otherwise, these guitars share the same construction throughout.
