I've got a hankering to get an upright bass and join a rockabilly band or even a bluegrass jam. So the question -- is rockabilly slap the kind of thing you need to start when you're younger and your hands are more flexible? I'm 60 and been messing with guitar and bass for over 40 years but I no longer play in bands and sometimes go weeks without picking up an instrument. I think my hands are in pretty good shape but I broke the knuckle on the ring finger of my right/slapping hand when I was 13 and the whole area of those last 3 fingers feels arthritic today. I'd hate to lay down the money on a bass and after a month of woodshedding find that I'm having hand pain/problems. Thoughts?
