Ovation Roundbacks - The Shape of Sound is Getting 'Round

This is an early Ovation Instruments promotional brochure highlighting their innovative roundback acoustic guitars featuring the proprietary Lyrachord bowl construction. The brochure focuses primarily on the Standard Balladeer (Model K-1006, list price $269.50) while also listing four other roundback models. Published by Ovation Instruments, a division of Kaman Corporation, New Hartford, Connecticut, the document emphasizes the acoustic superiority of the rounded bowl design over traditional flat-back guitars.
