Eastman was established in 1992 by Qian Ni, a former Boston University School of Music student after he noticed that many of his fellow students were either having to pay money they did not have for quality instruments, or battle it out with sub par offerings that fit their budget.
Eastman was set up around one key principle: craftsmanship. Eastman do not manufacture their guitars in Chinese factories, but instead hand-craft their guitars in luthier workshops. Eastman acoustics are also one of the only brands in the world that (almost) exclusively produce all solid guitars, with the exception of the PCH series, which still features a solid top.
All other Eastmans feature all-solid construction, and as you move up the series (from 1 to 40) the quality of the woods, as well as the electronics (where installed), increases as you go.
