Where to begin?
Gord-oh, I think he's asking about a DB. The biggest clue is that this is a DB forum.
jazzcat:
1) Did you search the Setup and Repair sections? That's where this really belongs.
2) On a DB, it's called "string height" and there is no fretboard.
3) Is the bass a rental or did you buy it from the shop? Who dressed the fingerboard and shaped the bridge?
4) It was perfectly fine to begin with? Did the bass actually change or are you saying that, compared to other basses and given your increased experience with it and other basses, you are now unhappy?
5) What does your teacher say about the setup on the bass?
6) What are your string heights?
7) What strings are you using?
8) What kind of bass is it? How much did you pay? Pictures might help.
9) How long have you been playing? What type of music do you play?
10) Does it sound substantially more powerful when someone else plays it?
You really haven't given us much to go on here. Depending on the answers to the questions above, you may get a more powerful sound by changing the setup, changing the strings, gaining more experience, all of the above or none of the above if the bass is simply an inferior instrument.
You've basically done the equivalent of posting on an auto forum, "Hey, I checked my timing and cleaned my injectors but I find that other cars are faster. What do I do?"
Your profile is empty. It would help if you told us more about yourself and the bass. Where do you live?
Category 5) subsection C?
