-
Physical Properties: Medium-density wood with uniform internal porosity and straight grain. Historically prized for its structural stability.
-
Dynamic response and bench experience: When cut and machined, it feels compact but not overly rigid. This more open cellular structure absorbs the sharpest high frequencies, resulting in an acoustic response focused on the mids and low-mids. It offers excellent natural sustain and a warm vibration, giving body and roundness to the note even before the electronics intervene.
OUR TONEWOODS
Anatomy of Sound
Guitarists are often divided into two categories: those who attribute almost magical powers to wood over acoustic performance and those who, on the contrary, believe that only the pickups and amplification count for an electric guitar.
The truth of modern violin making lies somewhere in between, and is a matter of pure design.
Pickups and electronics handle almost all of the signal coming out of the jack. But pickups don’t work in a vacuum: they capture the oscillation of a string anchored to a wooden body and neck. Tonewoods define the instrument’s chassis: their density and rigidity determine the speed of the attack, the richness of the primary harmonics, and the duration of the natural sustain even before the signal becomes electrical.
In this guide, you’ll find a candid analysis of the woods we select for our custom guitars . No commercial myths, just the physical characteristics of each wood and the experience of our laboratory work, to help you choose the ideal structural and aesthetic base for your custom instrument .
La verità della liuteria moderna sta nel mezzo, ed è una questione di pura progettazione.
I pickup e l’elettronica gestiscono la quasi totalità del segnale che esce dal jack. Ma i pickup non lavorano nel vuoto: catturano l’oscillazione di una corda ancorata a un corpo e a un manico di legno. I legni da liuteria (tonewoods) definiscono lo “chassis” dello strumento: la loro densità e rigidità determinano la velocità dell’attacco, la ricchezza delle armoniche primarie e la durata del sustain naturale prima ancora che il segnale diventi elettrico.
In questa guida trovi un’analisi schietta delle essenze che selezioniamo per le nostre chitarre di liuteria. Nessun mito commerciale, solo le caratteristiche fisiche di ogni legno e l’esperienza del nostro lavoro in laboratorio, per aiutarti a scegliere la base strutturale ed estetica ideale per il tuo strumento custom.
SECTION 1: BODY
The body constitutes the main mass of the guitar’s chassis. Its density affects the transmission of vibrations and the initial dynamic response.
Mogano (Mahogany)
Sound Analysis: Mahogany
Alder (Ontano)
-
Physical properties: Medium density wood, light and with very closed pores and dense, regular grain.
-
Dynamic response and bench experience: Alder is the benchmark for balance. With no extreme density peaks, it doesn’t overemphasize any one frequency. It offers an exceptionally balanced acoustic response, with clear mids, sweet highs, and controlled lows. On the bench, it’s a surefire winner: it acts like a neutral canvas, perfect for bringing out the character of your chosen pickups.
Sound Analysis: Alder
Ash
-
Physical properties: Wood characterized by wide, aesthetically spectacular grain and a very pronounced weight/stiffness ratio.
-
Dynamic response and bench experience: Its structure features alternating very hard and softer sections. This physical conformation offers an immediate snap (attack) under the pick. In terms of dynamic response, it tends to emphasize the extremes of the frequency range (deep lows and defined highs), leaving the mids slightly behind. It is the ideal wood for those seeking responsiveness and dynamics.
Sound Analysis: Ash
SECTION 2: TOP
On solid body guitars, the top, in addition to defining the aesthetics and visual impact of the instrument, acts as a mechanical compensation layer over the body wood.
Acero Marezzato (Flamed/Quilted Maple - Top)
-
Physical Properties: Extremely hard, compact, and heavy. The marbling is a spectacular three-dimensional figured grain.
-
Response and intended use: As a thin layer applied to the body (often paired with mahogany), flame maple acts as an “acoustic corrector.” Its physical rigidity accelerates the transmission of vibration, adding a crisper attack and a hint of brightness in the mid-to-high frequencies to the underlying body.
Sound Analysis: Flamed Maple
Flamed Ash (Top)
-
Physical Properties: This is an extraordinarily rare variant of standard ash, selected for its natural grain (a wavy pattern in the grain that creates a deep, three-dimensional effect under the varnish). Structurally, it combines the natural hardness of ash with a compact, elastic texture.
-
Response and intended use: Applied as a top layer over the body chassis, Flamed Ash doesn’t distort the instrument’s tone but rather accelerates its response. The rigidity of its surface increases the acoustic projection of notes and the definition of upper harmonics. Practically speaking, it gives the guitar a very responsive initial snap and a crisp attack, proving to be an excellent choice for maintaining definition and intelligibility of phrasing even in the presence of saturation and distorted sounds.
Sound Analysis: Flamed Ash
Flamed Poplar (Top)
-
Physical Properties: Poplar is structurally softer and lighter than maple or ash. In its marbled variant, it features unique waves and cross-grain patterns.
-
Response and intended use: Used as a thin top layer over the body chassis, Flamed Poplar has a nearly neutral acoustic impact. Its lower density means it doesn’t add artificial brightness or compression to the high frequencies, leaving the dynamic character of the body wood intact. It’s selected primarily for its extraordinary aesthetic appeal and acoustic transparency, ideal for those seeking a boutique look without altering the original sonic balance.

Poplar Burl (Flamed Burl- Top)
-
Physical Properties: Unlike linear grain, poplar burl is created from natural growths in the tree, creating a unique and unrepeatable tangle of fibers, knots, and eyelets. It is a structurally complex and porous wood, requiring advanced manufacturing processes to transform it into a solid, consistent, and unalterable soundboard.
-
Response and intended use: Installed as a top, poplar burl offers extreme acoustic transparency, acting as a surface that allows the free transmission of vibrations without coloring the instrument’s original timbre. It does not introduce emphasis on specific frequencies, preserving the dynamic character and frequency response dictated by the body and pickups. It is the choice of avant-garde violin making for those seeking an instrument that is both a hypnotic visual work of art and a pure vehicle for the sound of the underlying wood.
Sound Analysis: Poplar Burl
Beli (Beli - Top)
-
Physical Properties: Hardwood of African origin, characterized by regular dark streaks that closely resemble the aesthetics of Zebrano.
-
Response and intended use: It has a medium-high density. As a top, it offers excellent structural support, ensuring a good presence of midrange frequencies and an exotic, zebra-striped look strongly oriented towards modern and boutique luthiers.
Sound Analysis: Beli
Spalted Maple (Top)
-
Physical Properties: Unlike the regular, three-dimensional grain of flamed maple, spalted maple is not a deformation of the grain, but the result of a natural aging process that creates wild, black lines and geometries, similar to ink strokes. This makes the wood structurally less dense and more porous than standard maple.
-
Response and intended use: When used as a top, spalted maple loses much of the percussive punch and extreme brightness typical of flamed maple. Having lost cellular rigidity, it is acoustically very neutral: it doesn’t emphasize the mid-high frequencies or compress the attack. It offers almost complete tonal transparency, allowing the body chassis to define the instrument’s dynamics. It is chosen by those seeking an organic, asymmetrical look with a truly visual impact, without the need for a shiny “acoustic corrector” over the body.
Sound Analysis: Spalted Maple
Ash (Top)
-
Physical properties: Standard ash slab selected for the linearity and flame of the grain.
-
Response and intended use: Used as a top over a body of a different wood (e.g. Mahogany), it balances the instrument by adding attack and visual contrast, especially with see-through or sandblasted finishes.
Sound Analysis: Ash
Mahogany (Top)
-
Physical Properties: Matched mahogany slab for straightness and stability.
-
Response and intended use: Used as a top (for example, on ash or alder bodies), it serves to smooth out excessive highs. It evens out the mid-frequency response, slightly darkening the overall timbre and increasing the sensation of acoustic warmth.
Sound Analysis: Mahogany
SECTION 3: NECK
The neck controls the main mechanical tension of the instrument. Its rigidity directly affects the immediate transmission of vibration to the fingerboard and its sustain.
Maple (Neck)
-
Physical Properties: Straight-grain maple represents the absolute benchmark for neck construction. Characterized by short, dense, and visually attractive longitudinal grains, it offers excellent mechanical resistance to the constant traction exerted by the strings.
-
Response and intended use: Mechanically, the linearity of standard maple grain ensures excellent geometric stability over time. In terms of acoustic response, its crystalline rigidity eliminates the dispersion of kinetic energy: the vibration of the string is instantly reflected back to the body chassis. This translates into an immediate, crisp, and percussive note attack, with definition and a natural, always-focused sustain . It’s the choice of pure engineering substance for those seeking total reliability.
Sound Analysis: Maple
Flamed Maple (Neck)
-
Physical Properties: It represents one of the most exclusive and fascinating choices in boutique luthiery. Unlike the standard straight-grain version, Flamed Maple features wavy grain growth. This natural deformation creates parallel flamed grain that reacts to light with a profound three-dimensional effect.
-
Response and intended use: In terms of acoustic response, Flamed Maple maintains the species’s typical high-speed vibration transmission, but the wave-like structure of the grain slightly dampens the harsher, cutting high frequencies. It delivers a lightning-fast, percussive attack, while also enriching the note with a slightly softer, more complex midrange nuance. It is chosen for elite instruments where structural stability and acoustic responsiveness must blend with a luxurious visual impact and superior collectible value.
Sound Analysis: Flamed Maple
Mahogany (Neck)
-
Physical properties: Linear and constant fiber, excellent propensity for stability over time.
-
Response and intended use: A mahogany neck offers a smooth feel under the fingers. It absorbs the string’s elasticity differently than maple, producing a rich, enveloping vibration focused on midrange frequencies. Traditionally chosen for instruments oriented toward blues, jazz, and classic rock sounds due to its dark, mellow tone.
Sound Analysis: Mahogany
SECTION 4: FRETBOARD
The neck controls the main mechanical tension of the instrument. Its rigidity directly affects the immediate transmission of vibration to the fretboard and its sustain.
Maple (fretboard)
-
Physical Properties: The straight-grain maple used for the fingerboard offers a compact and uniform playing surface. Without the natural grain undulations typical of figured versions, this wood ensures excellent structural consistency. A protective finish (satin or gloss) is required to seal the pores and prevent the absorption of moisture and dirt during use.
-
Response and feel: The standard maple fingerboard offers a feeling of stability and smoothness from days gone by, with a uniform response across the entire range of the neck. In terms of dynamic response, the linearity of the grain translates into a percussive, immediate, and remarkably bright acoustic behavior. It reflects high frequencies with extreme clarity, offering a sharp snap under the pick and exceptional note separation, ideal for those seeking maximum intelligibility in fast passages, bends, and complex chords.
Sound Analysis: Maple
Flamed Maple (Fretboard)
-
Physical Properties: This elite selection brings the spectacular three-dimensional figured grain directly to the player’s fingertips. Unlike standard maple, the molecular structure features natural waves that create unique, iridescent plays of light once the protective finish is applied.
-
Response and feel: Visually mesmerizing when played, the flamed maple fingerboard offers a luxurious, smooth feel. Dynamically responsive, the wavy grain acts as a tiny natural dampener for the glassy, high frequencies. Snap and percussive attack remain lightning-fast, but the note is enriched with a warmer, rounder, and more present midrange nuance. It’s the ideal choice for those who want to combine the typical responsiveness of a maple neck with a striking boutique aesthetic and a slightly sweeter tone.
