Shop Iulius Acoustic Guitars — Where Acoustic Science Meets Handcrafted Lutherie
Iulius Guitars is the workshop of Giuliano Nicoletti, a professional acoustic engineer based in Saint-Etienne, France, who brings a genuinely rare perspective to guitar building. With over 25 years of experience designing high-performance monitors and loudspeakers, Nicoletti approaches the acoustic guitar the way an engineer approaches a precision instrument: with defined targets, measurable outcomes, and rigorous verification at every stage of the build.
That philosophy sets Iulius apart from virtually every other boutique luthier working today. Rather than relying solely on intuition and tradition, Nicoletti defines acoustic goals before a build begins and verifies results through precise measurement and tuning after assembly. Each top is calibrated as part of a complete, coupled resonant system, ensuring that the finished guitar behaves predictably and expressively under the player's hands.
The Iulius catalog currently spans both steel-string and nylon-string models, each representing a distinct acoustic character and musical role. The steel-string Orchestra model is engineered for clarity, warmth, and even response across the full fretboard, while the nylon-string offering is voiced for smooth dynamic control and clear register separation. Every instrument is entirely original in design, incorporating innovations aimed at improving playability, tone, and amplified performance.
Nicoletti is also a published author, active educator, and member of both the Association Professionnelle Luthier Guitare and European Guitar Builders, making Iulius one of the most intellectually engaged names in contemporary lutherie.
