The J17 »Allegria« is the entry-level model of the Sonntag archtops. It's distinguishing feature is the use of laminated sides and back, giving it a predilection for electrical amplification and making it highly resistant to feedback. The top however is of solid spruce and hand-carved, maintaining the Allegria's quick response and dynamic tone development.

The top mount pick-up creates the typical fat Jazz sound. The use of laminated back and sides, omission of ornamentation, and the Polyester-Finish make it affordable to newcomers on a budget price level.
