Gibson 1940 ES-100
The above photo compares my 1940 ES-100 and 1942 ES-125. There are several differences that can be noted right away and a few that take a little bit of looking to see. Click Gibson 1942 ES-125 to see more info on the actual model that was derived from the ES-100. This tab is mainly dedicated to the first appearance of the ES-100.
*Although a budget model, the ES-100 contained the same pickup unit as the ES-150 from the late 1930's. The only real difference to the naked eye was the body size, 14 3/4" wide at the lower bout (16" for the ES-150), and the rectangular white bobbin. Click 1938 ES-150 to see more of the ES-150.
Both ES-100 and ES-125 were derived from the late '30's acoustic L-38 which was identical, but lacking in electronics. The ES-100 has slimmer f-holes, a large 2-bar magnet which gave-way to the more compact metal covered P-13 in late 1940, and a nickel-plated tail-piece which was thinner at the top.
Both guitars share the same square-ended bakelite knobs, dark rosewood bridge that is wide at the base and body size.
As you look at these photos, take a second to view the 1942 ES-125 tab in order to compare the two guitars.
