"Introduced in 1941 as the successor to the ES-100, the ES-125 was an entry-level archtop electric guitar. It had one P-90 single-coil pickup in the neck position, and a volume control and tone control. The pre-war model, discontinued in 1942, had a smaller 14.5" body. When reintroduced in 1946 it had the larger 16.25" wide body that the ES-150 had. The unbound rosewood fingerboard initially sported pearl trapezoid inlays; later, it would have dot inlays.
In the mid-1950's, the ES-125T was introduced, which was an entry-level thinline archtop electric guitar based on the original ES-125. It would later add options for double P-90 pickups and a sharp cutaway similar to the ES-175. Both the thinline and the regular models would be discontinued by the 1970s."
