Hi-grade Sepele back and sides along with a solid Sepele top give the WD18SW a brilliant, responsive tone. The neck is made of genuine Mahogany with a 20-fret Ebony fingerboard. Grover 18:1 gold-tone tuners insure tuning stability. Final touches include a tortoise color pickguard, Abalone rosette and a uniquely styled Ebony "Butterfly" bridge.
