Gibson introduced its first electric guitar, the ES-150 in 1936. Its acceptance by influential players like Eddie Durham and Charlie Christian led to the manufacture of lower (ES-100) and higher end (ES-250) models over the next few years. These earliest electric guitars were amplified with a magnetic “bar” pickup (later called the Charlie Christian pickup) designed by Walter Fuller. The apex of Gibson’s pre-war electric production was the 17” wide ES-300 which used a long diagonal pickup in an attempt at a more natural acoustic sound. Gibson’s experimentation on and refinement of the electric guitar was halted briefly during World War II.
After the war, when production had fully resumed, a cutaway version of the ES-300 was designed called the ES-350 Premier. This guitar was initially equipped with one black plastic covered P-90 pickup (also designed by Walter Fuller) in the neck position. By 1949 a bridge pickup was added and the model became known simply as the ES-350. The ES-350 remained in production until 1956, when it was replaced by the thin-bodied ES-350T.
