Texte issue du catalogue de 1982:
"
Designed for the performer as well as the student, the Ovation Concert Classic projects a warm, mellow sound. It has a full 19 frets built on the standard 25 1/4". A sitka spruce top utilizing the Ovation VT-10 bracing pattern produces a full-range sound with a little more bass than the Ovation Classic. Mated with our exclusive five piece neck that allows adjustments to compensate for changes in humidity, the Ovation Concert Classic is an instrument of excellent tonal balance designed to be the perfect practice and performance nylon string guitar at a modest price.

Il y a des posts sur OFC à propos de cette guitare en 2004, ils parlent d'un prix de vente sur ebay de 250 à 350 $
