Demiurge Guitars

The philosophical and operational core of Demiurge Guitars is rooted in classical Greek culture and the scientific rigor of modern physics. The founder, Gianluca D’Emilio, has shown a visceral urge to understand the intimate essence of the electric guitar’s tone and playability since the age of 11. This research reached a turning point in 2018 when, after graduating in Physics from the University of Bologna, D’Emilio decided to apply the scientific method to woodworking, training under the guidance of the renowned master luthier Galeazzo Frudua. From that first workshop came the prototype of the Talisman model, the progenitor of a radical construction vision.

In 2021, the Demiurge brand was officially launched, from the Greek δημιουργός (demiurgos), the Platonic artisan-creator who shapes pre-existing matter, infusing it with order, geometry, and purpose. The logo itself, conceived by designer Gianmarco Martelli and inspired by William Blake’s work The Ancient of Days, depicts the divine hand radiating geometric light through a compass, a metaphor for the perfect architect of the universe. His subsequent specialization in musical instrument engineering and 3D modeling at the Polytechnic University of the Marche, combined with his work as a builder and custom pickup designer for Alusonic, allowed D’Emilio to forge his own path.

The collection

Every Demiurge instrument is built exclusively to order, conceived as a symbiotic collaboration that transforms the musician’s vision into a high-performance extension. Production is based on four proprietary design platforms, available in 6, 7, or 8-string configurations and multiscale architectures:

Talisman: An avant-garde reinterpretation of the classic T-style. It features a reversed offset design that optimizes the center of gravity and comfort while sitting. The jack access profiles and ergonomic contours (forearm bevel and belly cut) are mathematically calibrated to avoid hindering playing.
Sanctuary: A platform designed for maximum speed, precision, and action balance. It features a body thickness reduced to 38 mm with an inverted asymmetrical profile, carved at the bottom to accommodate the classical playing posture.
Leyline: A radical ergonomic evolution of the traditional Single Cut configuration. The body features a tapered thickness that slopes down from 40 mm at the center to 34 mm at the edges, connecting to the neck via a smooth, step-free joint, guaranteeing total access up to the 24th fret.
Heka (Headless & Multiscale): The ultimate technological expression of the brand. A compact and lightweight instrument, characterized by smooth transitions between convex and concave surfaces. It integrates a dedicated fanned-fret multiscale system to optimize the mechanical tension of extended registers, e.g., 26″ – 27 ¼” scale for the 8-string version.

Construction philosophy, techniques, and materials

The search for a sonic identity pushed Demiurge to completely internalize the design and manufacture of pickups, abandoning third-party industrial solutions to offer tone customization. Material physics is leveraged with an engineering approach through unique solutions:

Custom Bobbins via 3D Printing: To overcome the limitations of standard commercial adapters, D’Emilio uses industrial 3D printing to manufacture custom proprietary bobbins. This technique enabled the creation of the Prime 90 model (a true P90 in Humbucker format), where the height and width of the bobbin are calculated to accommodate the exact gauge and amount of wire (AWG 42) of historic P90s, preserving their dynamic and driven character.
Experimentation and Hybrid Pickups: The workshop selects magnet compounds based on the target resonance peak. While Alnico 2 and 5 are chosen for vintage and smooth equalization curves, in modern high-gain models like the Horizon and the Maelstrom, a revolutionary solution is applied: pairing Neodymium magnets (with very high magnetic flux and transient brilliance) with Alnico 5 and Ceramic magnets, broadening the frequency response spectrum.
Mechanical Neck Architecture: The necks, featuring a Slim-Taper C profile with rolled fretboard edges, are stabilized by the insertion of two structural carbon fiber reinforcement rods alongside a dual-action truss rod with spoke-wheel access at the base. In multiscale and extended-range guitars, the pickup slant, e.g., 10 degrees on 7-strings, is calculated to the millimeter to ensure perfect pole alignment under the string.
Hardware and Electronics Integration on PCB: Traditional point-to-point wired circuits are replaced by custom printed circuit board (PCB) systems made by Toma Systems, which eliminate tone degradation, eradicating background noise and offering total flexibility in internal switching schemes. For the Heka line, Demiurge adopts the Italian mechanical vanguard of Riviera Gear headless bridge systems with proprietary rear string locking.

Collaborations and recognitions

Gianluca D’Emilio’s training with Galeazzo Frudua and his industrial activity for Alusonic serve as a highly prestigious calling card in the European boutique lutherie landscape. Advanced research projects currently underway, such as the development of a Dummy Coil system based on reworked historical patents—designed to eliminate single-coil hum by inserting a neutral secondary coil in the spring cavity or control cavity—demonstrate the brand’s constant interaction with the concrete needs raised by professional musicians during top-tier studio sessions and live performances.

Direct experience

Each instrument starts from a specific technical base, for example, an alder or Khaya mahogany body, maple neck, Riviera Gear hardware, and Toma Systems PCB circuit, which the customer can shape to their liking.

The workshop offers an immersive digital and physical experience: through the use of advanced 3D modeling, the client can visualize and calculate the geometric flow of the instrument before physical crafting begins.
