The convention couldn't sound less rock-and-roll — the National Association of Music Merchants Show. But when the doors open at the Anaheim Convention Center, people stream in to scour rows of Fenders, Les Pauls and the oddball, custom-built creations such as the 5-foot-4-inch mermaid guitar crafted of 15 kinds of wood.
Except if, like George Gruhn, you know better. The 71-year-old Nashville dealer has sold guitars to Eric Clapton, Neil Young, Paul McCartney and Taylor Swift. Walking through NAMM with Gruhn is like shadowing Bill Belichick at the NFL Scouting Combine. There is great love for the product and great skepticism. What others might see as a boom — the seemingly endless line of manufacturers showcasing instruments — Gruhn sees as two trains on a collision course.
