you need to be a little more specific about what you are looking for.
what style or styles do you play?
what is your budget?
laminate, hybrid, or carved?
new or used?
Those are just a few of many questions to ask yourself.
One other thing is to find luthiers near you who also sell basses. its always best to try out something before buying.
The bass that is best for you is what you like and find comfortable to play. One person's favorite bass may not be the best for you.
