The scale or diapason of a guitar is the distance between the capo and the bridge saddles. This measurement represents the length of the vibrating part of the strings. The length of the scale affects various aspects of the instrument, including:

1. String tension: A longer scale requires more tension to reach the same note, which can make the strings harder to press.
2. Distance between keys: With a longer scale, the distance between frets increases, affecting playability.
3. Timbre and sustain: A longer scale tends to produce a sound with more sustain and a sharper attack.

The “multiscale” or “fanned fret” scale refers to a design in which the frets are not parallel to each other, but arranged in a fan shape. This means that the length of the scale varies between the strings: the lower strings have a longer scale, while the higher strings have a shorter scale. Benefits of multiscale guitar compared to a traditional scale:

• Improved intonation: Variation in scale length allows optimization of string tension, improving intonation across the entire fingerboard.
• Tuning stability: Due to the harmonized string tension, the guitar keeps tuning better, reducing the risk of detuning.
• Ergonomics: The fan design can provide a more natural position for the hand, making playing more comfortable and less tiring.
• Tonal versatility: Different string lengths allow for a richer and more varied sound, which is particularly appreciated in genres such as metal and progressive rock

The frets are the metal “bars” that subdivide the fingerboard into small parts and allow the string to lock as a result of pressure exerted by the musician, reducing its free vibrating length and, therefore, creating the sound.

The position of the frets is the result of a logarithmic calculation based on the length of the “scale” chosen; precise positioning determines precise pitch of each note.

The frets can vary in shape and material.

1. Jumbo frets: Jumbo frets are larger in height and width than standard frets, providing more space between the strings and the neck, making it easier to bend and pick notes. They are often preferred by guitarists who play musical genres such as blues, rock and metal.
2. Medium frets: these are intermediate in size between jumbo and vintage keys and are a versatile choice that can suit different playing styles.
3. Vintage frets: these are thinner and lower than jumbo and medium frets and can offer a more “vintage” feel and better tactile sensitivity. Most electric guitars have metal frets, usually nickel-silver alloy or stainless steel; they are durable, wear-resistant and offer a smooth surface on which the string rests to generate the note and can slide across the fretboard to generate the “bending” effect.

The choice of fret shape often depends on the guitarist’s personal preferences, the style of music he or she plays, and the tactile sensations he or she prefers while playing. Some guitarists prefer larger, spaced frets to facilitate bending and fast playing, while others may prefer thinner, lower frets for a more “vintage” feel and better tactile sensitivity.

Guitar and bass necks can have different types of cross section, shape, and thicknesses, which affect the comfort, playability, and sound of the instrument. Cross section: the cross section of the neck can vary between different shapes, including:

1. “C”-shaped profile, which is a common and comfortable shape that fits well in the hand.
2. “U”-shaped profile, which is thicker and more rounded than the “C”-shaped profile.
3. “V”-shaped profile, which has a more angular shape and can provide a more precise grip.

Fretboard width: Fretboard width can vary among different models of guitars and basses. Some instruments may have narrower or wider fingerboards depending on the style and preference of the player. Neck thickness: neck thickness can vary greatly from one instrument to another. Some necks may be thinner and faster, while others may be thicker and offer a more solid and stable feel.

The radius of a guitar fingerboard refers to the curvature of the fingerboard itself, in a hypothetical cross section . Guitar fretboards can have several curves, and the radius measures the diameter of the imaginary circle of which the fretboard itself would be an arc. This parameter influences the tactile feel of the fretboard itself and can affect the way the strings are played and bent. Typical radii for guitar fretboards usually range from 7.25 inches to 20 inches, with intermediate values such as 9.5 inches and 12 inches being quite common. A smaller radius means a more pronounced bend, while a larger radius means a flatter bend.

Dots on guitar necks are small carvings or inserts placed along the side or top of the guitar fingerboard. These dots are usually used as visual references to help guitarists “navigate” the neck while playing. They can be made of various materials such as mother-of-pearl, plastic, metal or wood. The dots are placed at certain frets, such as on the fifth, seventh, ninth and twelfth. These dots help guitarists quickly locate different notes and positions on the neck, making it easier to use the instrument during performance and study. In addition, the dots can vary in shape and size depending on the guitar manufacturer or specific model. Some guitarists also prefer to customize their dots with various materials such as mother-of-pearl or abalone or wood or resin inlays; some also prefer to associate a scenic look by using colored LEDs for unique designs to make their guitar more distinctive and personal.

Guitar pickups are electronic devices that transform string vibrations into electrical signals that can be amplified and reproduced through an amplifier. Pickups can be classified into two main categories: active pickups and passive pickups.

They consist of a magnet wrapped with copper wire that generates an electrical signal when the strings vibrate over it.

They do not require external power supply, as the signal produced is transmitted directly to the amplifier.

They have a warmer, more organic and more “vintage” sound than active pickups.

They are sensitive to the dynamics of the guitarist’s playing, reacting to changes in volume and intensity.

They contain a built-in preamplifier that requires external power, usually through a battery.

The preamplifier amplifies the signal from the pickup, improving frequency response and reducing background noise.

They have a higher output than passive pickups, offering a more powerful and defined sound.

They are less sensitive to feedback and may be more suitable for high-distortion music genres such as metal.

In summary, the main difference between active and passive pickups lies in the presence or absence of a built-in preamplifier. Passive pickups offer a more traditional, warm sound that is sensitive to the guitarist’s playing, while active pickups provide a more powerful, clean output suitable for heavier genres of music. The choice between active and passive pickups will depend on the desired sound, musical genre, and personal preference of the guitarist.

The tuning machines have the function of tuning and keeping the instrument in tune. They are usually located on the “headstock,” upstream of the fixed capo, and can be “in-line” or “symmetrical”; there are also instruments that do not have a “headstock” ( called “headless”): in this case tuning is done from the opposite side by means of special bridges that have the tuning system built in. There are two main categories: traditional and self-locking.

These are the ones used on most guitars.

To tighten a string, it is necessary to turn the mechanics’ knob, subject to special winding of the string on the mechanics’ shaft, until the string is tightened to the right pitch.

Once the string has been tightened, it is important to make it fit tightly on the capo to prevent it from unraveling and to keep the tuning stable.

Self-locking tuning machines have a mechanism inside the axle around which the string is wound, which locks the string in place once it is inserted and tightened properly. To tighten a string with self-locking tuning machines, it is necessary to insert the string through the hole in the mechanism and tighten it. The internal mechanism will lock the string in place without the need to make many turns around the axle Self-locking tuners offer faster string installation and can reduce the risk of string fraying; however, they may be a more expensive choice than non-self-locking tuners.

Ultimately, the choice between self-locking and non-self-locking tuning machines depends on the guitarist’s personal preference in terms of ease of use, speed of installation, and tuning stability.

Both types of tuning machines are used on high-quality guitars and can offer excellent performance depending on the musician’s needs.

There are several types of guitar bridge, each with specific characteristics that affect the sound, tuning stability, and ability to perform effects such as string bending. The three main types of guitar bridges are the fixed bridge (“Tune-o-matic” type), the fixed bridge with single saddles ( best suited for multiscale guitars), the tremolo bridge, and the Floyd Rose bridge.

is a type of bridge that is firmly attached to the guitar body and does not allow movement of the strings to change pitch. It offers greater tuning stability than tremolo bridges because the strings cannot be pulled or pushed to change pitch. It is ideal for those who prefer consistent tuning stability without the need for effects such as tremolo.

The tremolo bridge, or vibrato bridge, allows the pitch of the strings to be lowered by pressing the tremolo lever.

This type of bridge adds sound effects such as vibrato and string bending, however, it may require more maintenance to keep the tuning stable due to the tendency of the strings to fray with the use of tremolo.

is an advanced type of tremolo bridge that offers greater tuning stability than traditional tremolo bridges. It includes a string locking system at the capo that holds the strings in place and prevents slipping while using the tremolo. It is especially popular with guitarists who perform effects such as dive-bombing, in which the tremolo lever is pushed down to quickly lower the pitch of the strings. With this type of bridge, it is possible to push the lever toward the body of the guitar, lowering the pitch ( as is done with the tremolo bridge) but it is also possible to pull the lever in the opposite direction, creating a stretching of the strings, thus increasing the pitch. Because of this feature it is often also called a “tilting bridge.” The tremolo and Floyd Rose bridges, are penalizing for those who, during live sessions, were to break one or more strings: in fact, an imbalance would be created between the tension of the strings and that of the springs behind them in favor of the latter, which would cause the bridge to lower so as to make it impossible to play the instrument.

In conclusion, the choice between a fixed bridge, a tremolo bridge, and a Floyd Rose bridge depends on the guitarist’s personal preferences in terms of tuning stability, ability to perform tremolo effects, and ease of use. Each of these bridge types offers different advantages and disadvantages, and the choice will depend on the application and musical style of the guitarist.
