I have a very nice bass that I bought when I was much younger and didn't know much (hardly anything) about choosing basses. Basically I naively bought the one that I thought sounded the best in the shop. I didn't know it then, and nobody told me, but it's got a very long string length -- nearly 44 inches (my luthier calls it "a beast"). I'm not a full-time pro, and I went through a long periods where I played very little. I've managed to work with size -- or maybe ignore it, although sometimes it feels difficult and challenging, especially at the lower positions. My hands are average sized, and I am 5' 8" tall. Over the past few years I've been playing and practicing a lot more, doing regular gigs and rehearsals with a jazz quartet roughly every other week. I now realize (light bulb!) that most players use a bass with a shorter string length, and I am wondering (belatedly) whether I should get a different bass with a shorter string length. How much difference might a smaller bass make in terms of playability, possible fatigue, etc.? How does one tell what an appropriate sized bass is? Am I nuts to be playing a bass this large?
