Wayne Henderson - The Stradivari of the Blueridge
From the link:
Last year my brother made me aware of a book called Clapton’sGuitar – Watching Wayne Henderson Build the Perfect Instrument. The book tells the story of how Eric Clapton played a Henderson guitar in a recording studio back in 1994 and decided he had to have one. The wait period for a Wayne Henderson guitar is ten years, even for well known celebrities, such as Clapton. Henderson does not take shortcuts when it comes to his craft. Clapton received his Henderson in 2004.
