In electric guitars, the concept is different, but no less fundamental. Here, the body is the "engine" of the string vibrations. When you pluck a string, it vibrates. This vibration is transmitted to the bridge, and from the bridge it propagates to the wood of the guitar. The body, with its mass, density, and cellular structure, absorbs and reflects part of this energy. It is this exchange of energy that influences the sustain, attack, harmonic resonance, and even the "feel" of the instrument. Think of the body as a filter and a passive resonator. It doesn't amplify, but rather shapes the vibrations before they reach the pickups. A dense, rigid wood will tend to produce a quicker attack and greater sustain, with fewer complex harmonics. A lighter, more resonant wood might have a softer attack, a different sustain, and a more "open" sound. At first, when I was building my first bodies, I thought that the only important thing was the shape and that the wood was aesthetically "beautiful." Then I started to notice the differences. A mahogany body and an alder one, with the same pickups, sounded different<\/em>. Not just in the timbre, but in the way the note was born and died. There I realized that there was much more than I thought. Wood is not just a support for electronics; it is an integral part of the sound. The point is not to find the absolute "best" wood, but the one that suits the sound you have in mind and your style. Do you want an aggressive attack and a lot of punch? Or do you prefer a rounder sound and infinite sustain? The choice of material for the guitar soundboard<\/strong> \u00e8 il primo passo per raggiungere quel risultato. E fidatevi, si sente.<\/p>\n nnThe choice of wood for the guitar soundboard<\/strong> \u00e8 una delle decisioni pi\u00f9 importanti. Ogni legno ha le sue peculiarit\u00e0, il suo “carattere” sonoro, la sua densit\u00e0 e le sue caratteristiche di lavorazione. Non esiste un legno giusto o sbagliato, ma solo quello pi\u00f9 adatto al suono che cerchi.nnVediamo i classici e qualche alternativa interessante, con le mie osservazioni da “uomo del garage”:<\/p>\n n Characteristics:<\/strong> Warm, rich, with a pronounced midrange and exceptional sustain. It has good density, but is not excessively heavy.<\/em> Sound:<\/strong> Full, rounded notes with excellent projection. Perfect for blues, classic rock, and jazz. Examples:<\/strong> The king of Les Pauls, but also many SGs and some PRSs.<\/em> My experience:<\/strong> Ho fatto un body in mogano per una mia LP-style. Il sustain \u00e8 assurdo, le note sembrano non finire mai. Per\u00f2, se non stai attento, il suono pu\u00f2 diventare un po’ “scuro” con certi pickup. Bisogna bilanciare bene. \u00c8 un legno che perdona abbastanza la lavorazione, ma le venature possono essere un po’ “sfuggenti” se non si ha un buon filo sugli utensili.<\/p>\n n Characteristics:<\/strong> Very dense and rigid. It offers a bright attack and a very defined sound, with good sustain but different from mahogany.<\/em> Sound:<\/strong> Bright, with an emphasis on high frequencies and a distinctive "snap." Often used on mahogany body tops to add sparkle and attack. Examples:<\/strong> Fingerboards, necks, and the famous Les Paul tops. Sometimes also found in solid body versions, like some '70s Telecasters.<\/em> My experience:<\/strong> Lavorare l’acero \u00e8 pi\u00f9 impegnativo. \u00c8 duro, e le frese si consumano prima. Ma il risultato sonoro \u00e8 inconfondibile. Ho fatto un top in acero fiammato su un body di mogano, e la combinazione \u00e8 un classico per un motivo: ti d\u00e0 la botta dell’acero e la pienezza del mogano.<\/p>\n n Characteristics:<\/strong> There are two main types:n <\/em> Swamp Ash:<\/strong> Lightweight, porous, with an open grain. Very resonant, with good sustain and a bright, airy sound. Northern Ash:<\/strong> Thicker and heavier, less resonant but with a more pronounced attack and a more \u201cedgy\u201d sound.<\/em> Sound:<\/strong> Bright, with crystal-clear highs and defined lows. Excellent for funky, country, blues, and rock sounds. Swamp Ash is warmer than Northern Ash. Examples:<\/strong> Many vintage Fender Stratocasters and Telecasters used ash.<\/em> My experience:<\/strong> Ho fatto un body in Swamp Ash per una Telecaster. La leggerezza \u00e8 un plus enorme, e il suono \u00e8 davvero brillante e pieno di armoniche. Lavorarlo \u00e8 un piacere, \u00e8 relativamente morbido. Per\u00f2, attenzione ai pori aperti: assorbe un sacco di finitura! Preparatevi a parecchio pore filler.<\/p>\n n Characteristics:<\/strong> Lightweight, with good resonance and a balanced sound. It is a widely used and versatile wood.<\/em> Sound:<\/strong> Balanced, with a good midrange, present but not strident highs, and controlled bass. It's a bit of a "wild card" among body woods. Examples:<\/strong> Most modern Fender Stratocasters and Telecasters.n<\/em> My experience:<\/strong> L’ontano \u00e8 il mio punto di riferimento quando non so cosa scegliere. \u00c8 facile da lavorare, non \u00e8 troppo costoso e suona sempre bene, senza sorprese. Il suono \u00e8 neutro quel tanto che basta per far risaltare i pickup. Perfetto per la prima build, o quando vuoi un suono versatile.<\/p>\n Poplar:<\/strong> Inexpensive, lightweight, with a sound similar to alder but slightly softer. Often used for solid-color painted bodies, because its grain isn't always aesthetically appealing. <\/em> My advice:<\/strong> Se il budget \u00e8 stretto e vuoi verniciare coprente, il pioppo \u00e8 un’ottima scelta. Ho fatto qualche prototipo con il pioppo, e per il prezzo, il suono \u00e8 pi\u00f9 che dignitoso.<\/p>\n Basswood:<\/strong> Very light and smooth. It has a warm sound, with a rich midrange and a softer attack. Often used in shred or superstrat guitars, where a compact, saturated sound is desired. <\/em> My advice:<\/strong> If you are looking for lightness and a darker sound for distortion, basswood is valid. However, it is Very<\/em> morbido, si ammacca facilmente. State attenti in fase di lavorazione e montaggio.<\/p>\n Korina (Limba):<\/strong> Similar to mahogany, but often lighter and with slightly more resonance. It has a warm, defined sound, with nice sustain. <\/em> My advice:<\/strong> Se trovi la Korina a un prezzo decente, provala! \u00c8 un legno fantastico, con un aspetto stupendo. Ne ho usato un pezzo per un body semi-hollow, e il suono \u00e8 venuto fuori bellissimo, molto aperto e risonante.<\/p>\n A common mistake?<\/strong> Get fixated on the "perfect" wood you read about on some forum. The truth is that every piece of wood is unique. Two mahogany bodies will never sound the same. Exactly<\/em> allo stesso modo. L’importante \u00e8 capire le caratteristiche generali e poi fidarsi del proprio orecchio. E non aver paura di sperimentare.<\/p>\n nnOk, abbiamo parlato di legni. Ma non \u00e8 solo il tipo di legno a fare la differenza. Come lo tagliamo, quanto lo spessore, e come lo strutturiamo sono tutti fattori cruciali che influenzano il suono finale della nostra chitarra. Qui si entra nel vivo della lavorazione, ed \u00e8 dove, ammetto, ho combinato i miei primi veri disastri.<\/p>\n Body thickness is an often underestimated parameter. It's not just a question of ergonomics or weight. Thicker bodies (e.g. 50-55mm like Les Pauls):<\/strong> They tend to offer greater sustain and a fuller, darker sound. The greater mass vibrates longer and with more energy.<\/em> Thinner bodies (e.g. 42-45mm like Stratocasters and Telecasters):<\/strong> Hanno un attacco pi\u00f9 rapido, un suono pi\u00f9 brillante e una risonanza pi\u00f9 “viva”. La minore massa permette al legno di vibrare pi\u00f9 liberamente e di trasmettere pi\u00f9 velocemente le vibrazioni.nnLa mia prima Stratocaster DIY aveva un body che, per un errore di piallatura, era venuto un po’ troppo spesso, sui 48mm. Suonava bene, ma era meno “snappy” di una Strat standard e un po’ pi\u00f9 pesante. Quando ne ho fatta una con lo spessore classico di 44mm, la differenza si \u00e8 sentita subito: pi\u00f9 attacco, pi\u00f9 brillantezza. Ogni millimetro conta, soprattutto se si cercano sonorit\u00e0 specifiche.<\/p>\n Practical advice:<\/strong> Non inventatevi spessori a caso. Partite dagli standard delle chitarre che amate. Per una Strat\/Tele, puntate ai 44-45mm. Per una Les Paul, sui 50-55mm. Questo vi dar\u00e0 una base solida da cui partire.<\/p>\n The shape of an electric guitar's body has less of a sonic impact than the thickness or type of wood, but it's not entirely irrelevant. It affects the overall mass, balance, and, to a lesser extent, resonance. However, where shape really matters is in the distribution of mass. The real "holes" that matter are the routing: the cavities for the pickups, controls, and tremolo. Every time we remove wood, we're changing the mass and rigidity of the body. Routing for pickups:<\/strong> A single-coil humbucker requires less wood than a standard humbucker. This can slightly affect the mass and therefore the sound.<\/em> Control Cavity:<\/strong> The more routing there is, the more wood is removed, and the lighter and potentially more resonant the body becomes. I learned the hard way that precision in routing is essential. The first time I milled a cavity for a pickup, I used a somewhat hastily made template. The result? An irregular hole and a lot of peeled wood around it. There I understood that to get a good sound and a clean job, you need calm and, above all, solid and precise templates. If you're thinking about how modify your guitar<\/a> esistente per renderla chambered, sappi che \u00e8 un bel lavoretto, ma fattibile con i giusti strumenti e tanta pazienza.<\/p>\n nnNon tutti i body sono “solid body” pieni. Esistono diverse tecniche costruttive che alterano la massa e la risonanza:<\/p>\n Solid Body:<\/strong> The classic, a single block of wood (or several glued pieces). Maximum mass, maximum sustain, direct sound. Most electric guitars fall into this category.<\/em> Chambered Body (or Weight Relieved):<\/strong> The body is hollowed out internally to reduce weight, leaving only air chambers. This can slightly increase resonance and give a more "airy" sound, as well as saving your back. My experience:<\/strong> I built a chambered Telecaster. The weight has dropped significantly, and I've noticed a slight increase in acoustic resonance and sustain. It's not as radical a change as switching from one wood to another, but it's an excellent solution for balancing weight and sound. Just be careful not to overdo the carving, or the body will become too fragile.<\/em> Semi-Hollow Body:<\/strong> Here we have a body with much larger air chambers and often with the classic "f-holes" on the top soundboard. The sound is much more acoustic, warm, with a different sustain and a greater tendency to feedback at high volumes. My experience:<\/strong> Ho provato a fare una semi-hollow partendo da un body solid. \u00c8 un bel casino, non lo nego. Richiede un top incollato con precisione e una buona gestione delle f-holes. Il risultato per\u00f2 \u00e8 un suono unico, perfetto per blues e jazz.<\/p>\n Laminations and Tops:<\/strong> Many guitars, such as the Les Paul, have a maple top glued to a mahogany body. This isn't just aesthetics. The brighter and denser maple adds attack and clarity to the warm, dense sound of the mahogany. It's a synergy that creates a specific tone, the famous "Les Paul sound." In short, the guitar soundboard<\/strong> non \u00e8 solo un pezzo di legno, ma un sistema complesso. Ogni scelta, dal tipo di legno allo spessore, dalla forma ai routing, influisce sul risultato finale. Prendete il tempo necessario per pianificare ogni fase. Un errore in questa fase pu\u00f2 costare caro, in termini di tempo, denaro e frustrazione.<\/p>\n So far we've talked about the body as if it were a separate entity. But the guitar is a system, and each component interacts with the others. guitar soundboard<\/strong> non \u00e8 da meno: il suo suono si fonde e si modella con l’azione dei pickup e del ponte. Capire questa interazione \u00e8 fondamentale per ottenere il timbro desiderato.<\/p>\n nnI pickup non “sentono” solo la vibrazione della corda. Sentono anche le vibrazioni che la corda trasmette al ponte, e che il ponte trasferisce al legno del body. Il body, vibrando, restituisce energia alla corda, influenzando il suo sustain, la sua risonanza e il suo contenuto armonico. I pickup, a loro volta, traducono tutte queste sfumature in segnale elettrico.<\/p>\n <\/em> Resonant wood:<\/strong> A body made of Swamp Ash or Korina, which is highly resonant, will tend to produce a more "open" sound, rich in harmonics. The pickups will capture this complexity. Dense wood:<\/strong> A denser mahogany or Northern Ash body will offer longer sustain and a tighter attack. The pickups will convey this sonic \u201csolidity.\u201d I did an experiment a few years ago: I took the same pickups (a set of PAF-style humbuckers) and mounted them on two bodies identical in shape and thickness, but one in mahogany and the other in basswood. The result? On the mahogany, the sound was warmer, with almost infinite sustain and a midrange that embraced you. On the basswood, it was lighter, with a softer attack and a tighter sound, perfect for distortion. The difference was clear; it wasn't just a question of \u201ccoloration,\u201d but of how the note <\/em>he lived in the instrument.nnSo, don't think of pickups as "the" determining factor. They are an essential part, sure, but they work <\/em>with il legno. Un body che suona bene “da spento” (unplugged) \u00e8 gi\u00e0 un ottimo punto di partenza per un buon suono amplificato.<\/p>\n nnThe bridge is the main contact point between the strings and the guitar soundboard<\/strong>. La sua massa, il suo materiale e il suo tipo di ancoraggio influenzano direttamente come le vibrazioni vengono trasmesse e come il body risponde.<\/p>\n <\/em> Fixed Bridges (Tune-o-matic, Hardtail):<\/strong> These bridges are firmly anchored to the body, often with pins or screws that penetrate deep into the wood. This creates direct and solid contact, allowing for efficient transmission of vibrations. Advantages:<\/strong> They generally offer greater sustain and a more direct, focused resonance. The body wood has a more marked influence on the timbre. <\/em> My experience:<\/strong> Le mie chitarre con ponti fissi hanno sempre avuto un sustain pazzesco. Senti proprio il body che vibra sotto le mani. Un buon ponte fisso \u00e8 un investimento per il suono.<\/p>\n Tremolo Bridges (Vintage Synchronized, Floyd Rose, 2-Point):<\/strong> These bridges are designed to "float" or move, allowing for vibrato effects. Their contact with the body is less direct or more limited, depending on the design. <\/em> Advantages:<\/strong> They offer sonic versatility with vibrato effects. Disadvantages (potential):<\/strong> They can slightly reduce sustain compared to a fixed bridge, precisely because of their "floating" nature which disperses part of the vibrational energy. The resonance of the wood can be slightly attenuated. <\/em> My experience:<\/strong> Ho montato un Floyd Rose su una chitarra con body in tiglio. Il sustain era buono, ma non paragonabile a quello del mogano con tune-o-matic. Per\u00f2, per i dive bomb, non c’\u00e8 storia! \u00c8 un compromesso: guadagni in versatilit\u00e0, perdi un po’ in sustain “naturale”.<\/p>\n Bridge materials:<\/strong> The bridge material (steel, brass, die-cast zinc) also plays a role. Steel and brass tend to transmit vibrations better and produce a brighter, more resonant sound than die-cast zinc, which is cheaper and can dampen high frequencies somewhat. Ultimately, choosing the right body, pickups, and bridge should be a holistic process. It doesn't make sense to choose a super-resonant body and then install a bridge that dampens everything, or vice versa. It's an interconnected system where every piece contributes to the sonic puzzle. To delve deeper into the characteristics of woods and their interactions, an excellent resource is Warmoth's guide to tonewoods, which is always updated and incredibly detailed: Warmoth Tonewoods Guide<\/a>. Loro hanno fatto un sacco di ricerca e test, e le loro descrizioni sono molto utili per chi vuole capirne di pi\u00f9.<\/p>\n Ok, we've reached the crucial point: what to avoid and how to do things properly, without the worries I had the first few times. Build or choose the guitar soundboard<\/strong> non \u00e8 una scienza esatta, ma ci sono delle dritte che possono davvero salvare tempo, soldi e soprattutto la sanit\u00e0 mentale.<\/p>\n 1. Choosing wood "by eye" or just by price:<\/strong> The first body I made was made of a wood that looked "nice" and was cheap. The result? It was very heavy, didn't resonate much, and the grain was a nightmare to finish. Advise:<\/strong> Fai ricerca! Leggi, ascolta, chiedi. Non comprare il primo pezzo di legno che trovi. Parla con fornitori specializzati in legni per strumenti, non solo con la segheria sotto casa. Spesso hanno scarti o pezzi “musicali” a prezzi onesti.<\/p>\n 2. Don't consider the final weight:<\/strong> I had a guitar that, when finished, weighed almost 5 kg. It was beautiful to look at, but after half an hour on my feet, my back gave out. <\/em> Advise:<\/strong> If you don't want a heavy guitar, opt for woods like Swamp Ash, Alder, Poplar, or Basswood. If you really want Mahogany or Maple, consider a chambered body or one with a laminated top to reduce mass. Weigh the wood pieces.
