The Washburn N4 model designed by Nuno Bettencourt and Stephen Davies has enjoyed incredible success since its introduction nearly 25 years ago, in 1990.

Unlike most signature model guitars, which appeal only to fans of that artist, the N4 has earned acceptance on its own terms as a great player’s ax. In fact, over the past decade or so, it’s likely that most guitarists that have bought an N4 don’t even know Nuno from their nana.

While the new N4 Authentic is an exact replica of Bettencourt’s main N4 guitar, it’s certain to appeal as much to guitarists who want a stripped-down, high-performance instrument with a comfortable broken-in feel as it does to the most die-hard Extreme fan.
