Based on the provided reference, the fretboard radius on many metal guitars, specifically many pointy metal guitars, often boasts a 16-inch or higher radius.
The fretboard radius refers to the curvature of the guitar's fingerboard across its width. A smaller number indicates a more rounded (curved) surface, while a larger number indicates a flatter surface.
For metal guitars, particularly those designed for technical playing styles, a flatter fretboard radius like 16 inches or higher is often preferred.
Why a Flatter Radius for Metal?
A flatter radius provides several advantages favored by metal guitarists:
- Facilitates Faster Playing: A flatter surface can make it easier and faster to move your hand up and down the neck.
- Lower Action: It generally allows for a lower string action (distance between the strings and the fretboard) without the strings "fretting out" or buzzing excessively during string bends.
- Improved String Bends: Bending strings on a flatter radius can feel smoother and less likely to choke out, especially with larger bends.
Comparing Fretboard Radii
Different guitar types typically feature different fretboard radii, catering to their intended playing styles and historical designs. Here's a comparison based on the provided reference:
| Guitar Type | Typical Fretboard Radius | Curvature |
|---|---|---|
| Vintage-style Fender | 7.25 inches | More Curved |
| Modern Fender | 9.5 inches | Moderately Curved |
| PRS | 10 inches | Moderately Flat |
| Gibson | 12 inches | Flatter |
| Many Pointy Metal | 16 inches or higher | Very Flat |
As you can see, the 16-inch or higher radius common on many metal guitars represents a significant shift towards a flatter profile compared to traditional designs like vintage Fenders or even Gibsons.
Practical Considerations
When choosing a metal guitar, the fretboard radius is a key specification to consider, as it directly impacts the feel and playability, especially for techniques like shredding, sweep picking, and wide vibrato. While 16 inches or higher is common, some players might prefer slightly different radii, but the trend in the genre leans towards flatter profiles to support high-speed, technical playing.
