The Gibson ES-330 is a thinline hollow-body electric guitar model produced by the Gibson Guitar Corporation. It was first introduced in 1959.Though similar in appearance to the popular Gibson ES-335 guitar, the ES-330 is a fairly different guitar in construction and sound. While the ES-335 is a semi-hollow guitar (that is, the central part of the guitar body is a solid block while the wings of the guitar are hollow), the 330 is a fully hollow thinline guitar.
