Made for less than a decade, the Gibson ES-350 electric guitar was designed and released in '47 as version of the ES-300 archtop with cutaways. During the first year of production, the ES-350 had only one P-90 and sported a trapeze taipiece, but the ES-350 underwent a few changes: in 1948, another P-90 was added, and the bridge was swapped to a Tune-o-matic in '56.
