The G-245S was a Yamaha classical guitar made in the late 1970s and early 1980s with a subsequent model G-245SII running from 1981-1985 with many if not all of the same features. Both had a solid spruce top, laminate rosewood back and sides, 12-fret neck, black-bound 19-fret dark, Indian rosewood fretboard with side dot markers at 5th, 7th and 9th frets, a composite bridge with Indian rosewood, and a neck constructed of nato. One interesting feature of note is the 658 mm scale that the guitar possessed, like much of Yamaha's higher priced models throughout the '70s and mid '80s, making it one of the larger classical guitars Yamaha has produced, a scale length now only offered in their current GC line of classical guitars.
