The Euphoria series is a line of acoustic guitar models manufactured for Hoshino Gakki and sold under the Ibanez brand. It is a signature series of American guitarist Steve Vai. The initial model in the line, the EP7, was introduced in 2004. It was just the second signature acoustic guitar ever offered by Ibanez after the very limited Paul Gilbert signature PGA1000.
The Euphoria series is characterized by a thin body with a pointed Florentine cutaway to allow access to the upper frets of the 24-fret fingerboard. Special electronics allow the player to access a number of various acoustic sounds.
