When looking at a guitar or bass, most people expect the frets to run straight across the fingerboard. However, in some instruments you might notice that the frets appear angled or spread in different directions. These are called fanned frets, and they have become increasingly popular among modern musicians and instrument makers. The concept may look unusual at first glance, but fanned frets are designed with very practical purposes in mind. They help improve tuning stability, enhance playability, and create a more balanced tone across all strings. To understand what fanned frets are, it is helpful to explore their design, benefits, and impact on music.
Understanding the Design of Fanned Frets
Fanned frets, sometimes referred to as multiscale frets, involve a fingerboard where each string has a slightly different scale length. Instead of having frets that run parallel to one another, the frets are arranged at angles. The result is a fan-like appearance, hence the name. The idea is that lower strings, which produce deeper tones, benefit from a longer scale length, while higher strings are easier to play and sound clearer with a shorter scale length. This design creates an instrument that balances comfort and tonal quality.
The Concept of Multiscale
The term multiscale is often used interchangeably with fanned frets. This is because the instrument incorporates more than one scale length at the same time. Traditional guitars use a single scale length, such as 25.5 inches or 24.75 inches. In contrast, a fanned fret guitar might have the low string at 27 inches and the high string at 25 inches. This subtle difference changes the feel and the sound in significant ways.
Why Fanned Frets Exist
The development of fanned frets was not just about aesthetics. Musicians and luthiers sought solutions to challenges that arose with conventional instruments. Standard fretboards can sometimes create issues with intonation, string tension, and playability, especially on extended-range instruments like seven- or eight-string guitars. By adjusting the scale length for each string, fanned frets offer a more natural alignment for the fingers and improved sound balance across the instrument.
Improved String Tension
One of the main reasons fanned frets are used is to improve string tension. On a traditional guitar, the lowest string often feels floppy, especially on extended-range models. With fanned frets, the longer scale length on the bass side increases tension and gives the string a tighter, more controlled feel. At the same time, the treble strings remain shorter and easier to bend, providing a smoother playing experience.
Better Intonation
Another advantage of fanned frets is better intonation. Because the strings each have a scale length suited to their pitch, they can stay more in tune across the fingerboard. This results in chords and scales sounding cleaner and more accurate, particularly in complex music styles where precision matters.
Benefits of Fanned Frets
The practical benefits of fanned frets go beyond just looks. Many musicians find that switching to a multiscale instrument improves their playing comfort and tone. Here are some key advantages
- Ergonomic hand positioningThe angled frets follow the natural movement of the fingers, reducing strain during long playing sessions.
- Balanced toneBass notes have more clarity while treble notes retain warmth and ease of play.
- Extended range instrumentsSeven-, eight-, or nine-string guitars benefit greatly from the tension adjustments fanned frets provide.
- Improved sustainThe longer scale length on bass strings can create deeper resonance and sustain.
How Fanned Frets Affect Playability
One of the common questions musicians ask is whether fanned frets are difficult to play. While they may look intimidating at first, most guitarists adapt quickly. The frets are designed to match the natural angle of the fingers when moving up and down the neck. This means that many players find them more comfortable over time. Chord shapes remain the same as on a traditional guitar, though the hand angle adjusts slightly depending on position.
The Learning Curve
Although the transition is not overly complex, beginners might need a short adjustment period. Players who are used to straight frets may feel unusual at first, but with practice, the angled design feels intuitive. Many musicians report that after adapting, returning to a standard guitar can feel less ergonomic.
Applications of Fanned Frets in Music
Fanned frets are not just a novelty; they are widely used in different genres of music. Progressive metal, jazz fusion, and experimental rock are some styles where multiscale instruments shine. Bands and solo artists who require extended tuning stability and tonal clarity often prefer guitars and basses with fanned frets.
Fanned Frets in Bass Guitars
Bass players particularly appreciate fanned frets. Since bass strings are thicker and more prone to tension issues, the longer scale length provides better definition. A fanned fret bass allows the low notes to sound powerful without becoming muddy, while the higher strings remain smooth and responsive.
History and Development
The idea of fanned frets has existed for centuries, with early experiments appearing in lutes and other stringed instruments. However, the modern version gained popularity in recent decades, thanks to innovative guitar makers exploring new designs. Custom luthiers and some major brands have incorporated multiscale instruments into their offerings, making them more accessible to players around the world.
Considerations Before Choosing Fanned Frets
While fanned frets offer many benefits, they may not be for everyone. Musicians considering them should think about their playing style, comfort level, and the type of music they perform. Some factors to keep in mind include
- The adjustment period required when switching from straight frets
- Availability of fanned fret instruments, which may be less common than traditional ones
- Cost, as custom-built multiscale guitars can be more expensive
- Compatibility with standard cases and accessories, which may vary
Future of Fanned Frets
As more musicians recognize the advantages of multiscale instruments, fanned frets are likely to become even more popular. Advances in design and manufacturing make it easier for instrument makers to produce them with precision. Many believe that fanned frets represent the next step in the evolution of string instruments, blending tradition with innovation.
Fanned frets may look unconventional, but their purpose is rooted in solving real problems faced by musicians. By offering improved string tension, better intonation, and enhanced comfort, they appeal to players seeking both technical precision and ergonomic design. Whether on guitars or basses, fanned frets allow for a richer playing experience and a more balanced sound across the instrument. For anyone curious about modern instrument design, fanned frets are worth exploring as a serious option in the world of music.
