giulio negrini | italian master Luthier

“…EVERY GNG GUITAR IS NOT JUST AN INSTRUMENT BUT A COLLABRATIVE ART PIECE…”

  • Giulio earned his Master Luthier’s degree in 2007 from the prestigious Violin and Bow Making School in Gubbio, Italy, where he was trained in the classical “Cremonese” techniques of Stradivarius, Guarneri, and Amati. His expertise extends beyond traditional violin-making, having honed his skills in specialized seminars on violin restoration (Adam Whone), archtop guitar techniques (John Monteleone), and inlay artistry (William "Grit" Laskin).

    An accomplished guitarist himself, Giulio’s experience as a hard-rock musician gives him a unique perspective on player needs, informing his focus on exceptional playability, smooth neck profiles, and ergonomic designs.

    His instruments often feature bold aesthetics, including themed custom inlays, multi-scale fretboards, extended range configurations, and hi-gloss finishes. Each guitar is tailored to the player's specifications, with hand-wound pickups, premium hardware, and a curated selection of rare, high-grade tonewoods.

    Giulio is a proud member of the European Guitar Builders Association, NAMM, and the Boutique Guitar Showcase. He has crafted over 300 instruments, yet remains deeply committed to continual learning, drawing inspiration from woodworking traditions and artistic innovation.

    For Giulio, every GNG guitar is not just an instrument but a collaborative art piece, reflecting the shared vision between maker and player. His passion for perfection and dedication to the craft make GNG a name synonymous with exceptional quality and artistry in the world of modern guitar-making.
