It’s too early to say what the classic guitar of the 2020s will be, but headless guitars have made a comeback. These offer superb balance, strong sustain with no headstock to absorb string vibration, and unrivalled tuning stability. To facilitate technical playing, ergonomic body designs and active pickups are common. Check out Yvette Young’s Strandberg, Lee McKinney’s Kiesel, or Tosin Abasi’s own Abasi Concepts to see the frontiers of guitar playing and design.
