Sorry to hear about the osteoporosis arthritis and some other comments on here. If you feel like your bass-playing days are coming to an end due to 'left-hand' issues, I can't recommend your trying out a Kala electric U-Bass highly enough. If you have had any previous experience with 'rubber-band' mini-basses, forget it. The Kala uses a different type of string and is a completely different animal. Once in tune, it stays there; is seriously lightweight, which addresses any shoulder issues for those with arthritis/back pain, and sounds something like a cross between a DB and a Precision. I used mine recently with a full band and more than a few folk were up and asking what this small instrument with the deep bass voice was. These are not cheap - retailing at around £1250 -but they really are proper instruments and not 'toys'. I thought that posting this might help anyone reading who is unaware of this bass. Of course, it goes without saying, I have no connection to the company or any other incentive to write this other than trying to assist those experiencing pain when playing a 'normal' bass. Photo of my bass for illustration.
Best Snork.
