The first instrument I had was made in the late '70s. Back then they had basically one tuning. I shifted slightly away from that tuning right away (to what is now called the Baritone Melody Tuning), because I wanted more string overlap between the two sides.The instrument I currently play has an active pickup system, Fret Rails, a fully adjustible bridge, adjustible truss, Flaps adjustible nut. Even with all of these advances, I'm always struck when I play the older instrument how good they were even then. Emmett's always been great at implementing his ideas.
