text: The term archtop refers to a method of construction subtly different from the typical acoustic (or "folk" or "western" or "steel-string" guitar): the top is formed from a moderately thick (1 inch (2.5 cm)) piece of wood, which is then carved into a thin (0.1 inches (0.25 cm)) domed shape, whereas conventional acoustic guitars have a thin, flat top.
