To compile the list, we went through every issue in GP’s illustrious 40-year history. Along the way, we found amazing interviews, hilarious ads, and a metric ton of great lessons. We picked one classic from every year and did our best to present examples for every skill level and genre. Play them all or just cherry-pick your favorites. As you do, keep in mind that you’re adding cool concepts to your musical toolbox that will lend depth, vibe, and scary-good chops to your guitar playing. This collection of lesson snippets should be an endless source of inspiration and fun. Our apologies to all the great teachers who aren’t represented herein, but you’re still a vital part of the GP legacy—and you can take solace in the knowledge that you got bumped off the list by cats like Chet Atkins, Wes Montgomery, Eddie Van Halen, and Joni Mitchell.
