The season of the summer jams is here, and Gibson Original Acoustic Instruments kicks off the pickin' and grinnin' around campfires and festival sites across the country with the introduction of the new Jam Master Series line of mandolins. Both models in the new series - an A-style and an F-style - focus on a no-compromises approach to tone and playability, while easing back on the trimmings to provide a roadworthy Gibson mandolin at an attractive price. The Jam Master A- and F-style mandolins descend straight out of hallowed Gibson tradition, but offer two accessible new options to the player who wants to get their jam on, in whatever setting, with whatever kind of music.
