Top Author for Guitar Books?

This is an easy one for me. Although I may be personally biased and my good friend is far too humble to accept the praise, I believe that Wolf Marshall is the greatest guitar author and historian of our time, hands down. When you consider the fact that his prolific output spans so many genres, including blues, rock, and jazz, then combine that with his great attention to accuracy and detail, not to mention his pure passion and obsession for preserving the legacy of artists and helping aspiring guitarists to evolve? Well, have I left anything out? Trust me, Wolf Marshall has worked hard to be the best. It shows.
