This warranty covers your Galliard accordion against defects in materials and workmanship. Its not necessary to register your warranty. Please keep you're original sales receipt as proof of purchase. If warranty work is required bring the receipt with your accordian to the original point of purchase. Dealers will evaluate the accordion to determine whether they can be serviced locally or should be returned to Galliard. Work performed by unauthorized persons will avoid your warranty.
