The Gibson ES-335 is the world's first commercial semi-hollowbody electric guitar, sometimes known as semi-acoustic. Released by the Gibson Guitar Corporation as part of its ES (Electric Spanish) series in 1958, it is neither fully hollow nor fully solid; instead, a solid maple wood block runs through the center of its body. The side "wings" formed by the two "cutaways" into its upper bouts are hollow, and the top has two violin-style f-holes over the hollow chambers. Since its release, Gibson has released numerous variations of and other models based on the design of the ES-335. The ES-335 is currently manufactured at the Gibson Nashville facility. It was also produced at Gibson Memphis from 2000 until 2019, when the Memphis facility was closed. History Before 1952, Gibson produced only hollow-body guitars, which are prone to feedback when amplified loudly. That year saw the introduction of their first solid-body, the Gibson Les Paul, a significantly different instrument from Les Paul's early electric guitar experiment, "The Log", which consisted of a center block with detachable chambers on both sides, a neck, hardware, and a pickup attached. By 1958 Gibson was making a few solid-body models which had much lower feedback and better sustain but lacked the darker, warmer tone and unamplified volume of hollow bodies. The ES-335 was an attempt to find a middle ground: a warmer tone than a solid body produced with almost as little feedback. Though semi-hollow-bodies like the ES-335 are essentially a compromise of earlier designs, they are for this reason extremely flexible, as evidenced by the ES-335's popularity in a wide range of music, including blues, jazz, and rock. With a basic price of $267.50, it quickly became a best-seller, and has been in continuous production since 1958. The first major update came in mid 1962, with the most visible change being the neck markers; early models had dots (hence "dot neck"), later models had blocks. Models Some models (ES-347, ES-369) feature a coil split switch, which allows the humbuckers to produce a "single-coil" sound. The ES-335 Pro, ES-335TD CRS and CRR models were equipped with Gibson "Dirty Fingers" humbuckers, which had a significantly higher output than the standard pickups. The company has produced a number of signature guitars as well, such as Trini Lopez-inspired model (1964–1970) with narrow diamond-shaped soundholes replacing the f-holes, a Firebird-style headstock with all the tuners on one side, and slashed-diamond inlays.
