It has different bracing to a 335 that allows it to be played like any normal solid body. Unlike the ES-335 which has a solid maple block running through the middle, this top and back on this guitar will move and resonate like an acoustic. Though the Casino looks like its Gibson brother, the ES-335, it has one major difference and that is the fact that the Casino is fully hollow inside.
Once Paul McCartney discovered the casino, the other members bought into it because its diverse range of sounds and stunning acoustic qualities. Epiphone have decided to give the world a high-end version of the Casino so that you too can get those fantastic hollowbody sounds, as well as the mildly driven p90 tones.
Mostly due to the fact that it was the instrument of choice for that little band from Liverpool, The Beatles. The Epiphone Casino is one of the most iconic guitars in the world.
