i dont know very much about setting up a bass or having it done, but i think mine needs it. the e strings buzzes when i play high up on it. the thing is i dont know much about all the different things involved (things like action and other adjustments, i dont even know how i want them), and wouldnt know what to tell someone i wanted. would i be able to be like "make it sound as good a possible" and "make it easy to play"? also how much does this usually cost?
