Any suggestions for prolonging my bass-playing life? Getting old, 51 is not that old, but I have bad tendon issues in my left arm and elbow, and pain developing in the tendons of my thumbs, signs of carpel Tunnel...you name it! Currently I practice with a Fender Jazz (which I love but is heavy) but play out with an Ibanez SR500 (love that thin neck!)which I can fly on after playing the Jazz, both with Black nylon flats. I think this recipe will get a few more years, but I want to die with my bass in hand! Any thoughts?
