Gibson also owns and makes guitars under such brands as Epiphone, Kramer, Valley Arts, Tobias, Steinberger, and Kalamazoo. In addition to guitars, the company makes pianos through its Baldwin unit, Slingerland drums, as well as many accessory items. Company namesake Orville Gibson made mandolins in Kalamazoo, Michigan, in the late 1890s. Gibson used the same type of carved, arched tops in archtop acoustic guitars, and by the 1930s was also making flattop acoustic guitars and electric guitars. Charlie Christian, one of the first well-known electric guitarists, helped to popularize Gibson's electric guitars with his use of the ES-150 and ES-200.
