Hi, I've been playing guitar for about 25 years, not professionally. The past few years I've really put a lot into it, and I began playing fingerstyle blues. This has gotten me obsessed with rhythm. Someone had given me a nineties MIJ P Bass a few years ago, and I've been playing it quite a bit lately. Previously, I could play bass in a pinch, but I would never call myself a bass player, but now, I would like to call myself a bass player. Anyone, I'm finding it challenging. Playing guitar, rarely does my hand get tired, but the bass tires my hand out pretty quickly. It's difficult to play in first position without making the bass rattle and/or buzz, and I hate when it rattles and buzzes. Also, fretting with my pinkie requires a lot more control than on the guitar, and I have to stretch further, so that doesn't sound so hot.I record my own music, and it would be really nice to feel competent on a bass (not merely 'adequate'). Any pointers? How long will it take for my hand to "set"? Yes, I know that is kind of a silly question, but consider that I know what I want to do, I just don't have the physical ability to execute...presuming I play an hour a day, how long before playing the bass stops feeling like an endurance test?
