Les Paul will forever be known for his role in the popularity of the electric guitar, the design of the Gibson Les Paul guitar, the multi track recording, the early guitar effects, and his million selling recordings with wife Mary Ford. However, did you know Les also appeared as product endorsee in more NAMM shows than just about any other artist? From the 1950s onward Les stood in the Gibson booth shaking hands and signing autographs while promoting the guitar line. In fact in 2006, after the Gibson Company purchased Baldwin Pianos, Les was at the NAMM show promoting the Les Paul Baldwin Piano. Les passed away in August 2009 at the age of 94.
