The 529 appears in both the 1980 and 1982 mandolin catalogs. Initally, the model featured a dot inlay fingerboard, as shown in the 1980 Ibanez Mandolin Catalog.
The later version in the 1982 catalog shows a fancy fingerboard inlay, likely used to distinguish it from the newly introduced, cheaper 528 mandolin which had a dot inlay fingerboard.
The 529 is part of what I call the “Modern Series” of Ibanez mandolins. By the 1980′s, Ibanez had reached a point where they were no longer directly copying Gibson designs but developing original designs. The snakehead and hollow scroll are unlike any previous models. Although not a direct copy, some inspiration from the work of John Monteleone, who was a prominent luthier at the time, and Gibson lump scroll models is evident.
The striking hand-rubbed Antique Violin finish was reserved for the most high-end Ibanez instruments, and the dramatic top carve is reminiscent of the 527. Note the unusual shape of the f-holes. The overall effect is a very high-end instrument with excellent craftsmanship.
