John Mayer's Perspective on Neck Radius in Electric Guitars: Debunking the Myth

John Mayer, known for his PRS Silver Sky signature guitar, shared his perspective on the importance of neck radius in electric guitars. Despite the common belief that fretboard radius affects playability, Mayer believes it doesn't hold as much significance as many think. The development of his signature guitar took two years and was a learning experience for him, as he previously didn't pay much attention to neck radius.
Neck radius, or fretboard radius, refers to the curvature of the fretboard. Traditional wisdom suggests that rounder fretboards make fretting easier, while flatter necks are better for bends and solos. Different guitar manufacturers have their preferred measurements, with vintage-style guitars often featuring a 7.25\" radius and modern builds using 9.5\" or 12\" radii. However, Mayer argues that the difference between these measurements is minimal and not as crucial as other factors.
Mayer emphasizes that every guitar is unique and has various points of variation, with neck profile being just one detail among many. He believes that the key to comparing neck radii accurately would be to build two identical guitars with only that difference. Mayer asserts that with the right setup and level frets, he can perform just as well on his PRS Silver Sky with its specific neck radius as he could on a guitar with a different radius.
In a recent interview with Guitar World, Mayer and Paul Reed Smith discussed the creation of the Silver Sky. Smith recalled an interesting discovery he made when examining Mayer's 1964 Stratocaster. The new issue of Guitar World features a list of the best guitar gear of the 21st century, providing insights into the world of guitar playing and equipment.
