I'm just recovering from tendonities (did I spell that right?). For almost three months now. The doctor says I must take it really easy for two more months. That is five months wsated of my life, since I'm not able to play bass. I don't learn anything by not playing. I have read a lot of books on bass and general music theory, so that the time wouldn't be all wasted, but I feel that it sin't enough. I must learn more. Can anyone give me hints on how to work on my skills without playing bass?
