UNRESERVED. One of Gibson's most popular flattop guitars, the LG-2 made its debut in 1942 and remained in the catalog for the next 20 years, until it was re-christened as the B-25 in 1962. Together with its blonde counterpart, the LG-3, these two models were the only smaller Gibson flattops of their era built with an X-braced soundboard. With its ultra-light construction, tall skinny braces, and stiff resonant soundboard, the LG-2 combines compact size with jumbo guitar projection and sustain.
