I recently discovered that the Washburn "4N" now played by Nuno Bettencourt of Extreme is my old "Davies N4" that he purchased used and that Washburn is now creating replicas of that same guitar. Here is the story of how the "4N" came to be the way it is and why there would be a reason to create a replica of it even though an N4 is still readily available.
