The S470 was introduced in the '92-'93 catalog in the US as a stop-tail version only, but there were
vintage trem and an Edge equipped versions in the 1993 catalog. The 470 was available exclusively with
dot inlays, and the 540's that were it's contemporaries had oval or shark's tooth inlays... The '91-'92 catalog has the 540SFM with dots, but there's the "Custom Made" inlay at the 21st fret, which is absent on the 470... Production prior to '92 probably assures a 540... Otherwise, the 540 has the Dimarzio-made IBZ/USA "F" and "C" marque pickups to distinguish it from the 470's "V" pickups... Both models are mahogany, but the 540 offered maple fretboards with oval markers from time to time...
