For the project, Kaman chose a small team of aerospace engineers and technicians, several of whom were woodworking hobbyists as well.One of these was Charles Mc Donough, who created the Ovation Adamas model.The Kaman Corporation soon diversified, branching into nuclear weapons testing, commercial helicopter flight, development and testing of chemicals, and helicopter bearings production.In the early 1960s, however, financial problems from the failure of their commercial flight division forced them to expand into new markets, such as entertainment and leisure.This unit provides volume knob, 3-band equalizers, tune button, LED display, and is a standard on entry-models (Celebrity and Applause in 2011–2012).
In 1965-1967, the Ovation Guitar Company produced a signature guitar for Josh White, which was the first signature guitar made for an African American.
Kaman founded Ovation Instruments, and in 1965 its engineers and luthiers (guitar makers) worked to improve acoustic guitars by changing their conventional materials.
The R&D team spent months building and testing prototype instruments.
The Ovation Roundback Balladeer first caught national attention in 1968 when Glen Campbell hosted a variety show he called The Glen Campbell Goodtime Hour on CBS, and in the following year, 1969, he became one of Ovation's first endorsers.
