Joe Perry’s tobacco burst was cool, but Number One was the reason Perry – and every other rocker – wanted a Les Paul. Jimmy Page bought the guitar from Joe Walsh, and shaved the neck dangerously thin. Page’s tone on Led Zeppelin II – Number One into a cranked Marshall Plexi – defined the sound of hard rock. It’s been refinished, a phase switch added, and the bridge pickup changed to a 60s model, but it’s worth more than any untouched original.
