The Gibson BR-6 is one of the larger models in the postwar BR lap steel amplifier series, moving up to 6L6 output tubes for increased headroom and a bolder, more open low end than the 6V6-equipped smaller models. Designed for gigging Hawaiian and country guitarists who needed more volume, the BR-6 retains the smooth, warm character of the BR line while adding the extended frequency response and projection that 6L6 tubes provide. It represents a significant step up in power within Gibson's budget postwar range.
