24 pages
This document consists of internal Ovation guitar research and engineering notes from 1976, documenting deflection measurements, stiffness ratings, and acoustic properties of guitar tops across multiple guitar prototypes numbered roughly #15 through #59. The notes record comparative data on parameters labeled R, L, S, N, K, and FF, tracking changes due to bracing, bridge braces, laminates, rim construction, and other modifications. The material appears to be pre-production or quality control research intended to optimize guitar top performance, with dates ranging from late 1975 through late 1976.
