John Petrucci, Dream Theater’s founder, is a symbol of progressive metal. Discover his story, signature gear and the secret behind his tone.

Introduction

John Petrucci is one of the most influential guitarists in the history of progressive metal. Born in 1967 in New York, he co-founded Dream Theater, a band that changed the boundaries of technical and emotional expression in modern rock. His sound combines precision, harmony, and the soul of a classical composer. Petrucci is not only a shredder: he’s an architect of tone, a visionary who turns complexity into music.

Throughout his career, he has pursued the perfect tone. His collaboration with Mesa Boogie and Ernie Ball Music Man led to signature gear that defines his sound. His JP-2C amp blends raw power and control, while the Majesty guitar is a masterpiece of modern design. He balances mechanical precision and emotional impact in every solo he plays. For musicians, Petrucci represents the balance between discipline and creativity — proof that technique and emotion can coexist.
