Speaking as someone who recently started having lessons after about 12 years of playing (with Steve Lawson - from TB ask a pro forum). I can safely say getting the right teacher is paramount, anyone will just not do!!!
Things I think are important are:
*Everything Stephanie says above!
*Finding someone who you like and respect as a person/musician/bassplayer - in that order.
*Someone who has a wide knowledge of different styles.
*A teacher should impress and inspire you a as musician and player (but they shouldnt try to!)
*A teacher should enjoy teaching you.
*A teacher should adapt to how you learn best and work at your pace.
You should think about what you want from the lessons? - Even tho as James S says above you dont know what you want to learn until you've learnt it, you probably have an idea about where you want to go as a musician/bassist, you probably have ideas and dreams and they are important.
I dont neccessarily agree with the fact that they should neccessarily be a working bassist. I think someone who enjoys teaching and loves music is infinitley more important.
