archtop
An archtop guitar is a guitar with a curved top and back, typically built with a hollow body and f-holes. The top is usually carved spruce or laminated spruce, and the back and sides are commonly maple or laminate. Many archtops feature a floating magnetic pickup and a tailpiece rather than a fixed bridge. The arched top design helps produce a warm, projecting tone when amplified, which has made arch-tops especially associated with jazz.
Construction variants include carved-top archtops, where the top is carved from solid wood, and laminated-top archtops,
History and development: The arch-top concept evolved from late 19th-century guitar design, with early archtop instruments
Playing and use: Archtops are prized for their warm midrange, rich sustain, and strong projection when amplified.
