I've got a Warwick Corvette Standard 5-String. It is about three months old. My guitar tech noted a slight twist in the neck when setting it up. He said solving one problem on one side of the neck will lead to buzzing on the other. It is set up with comfortable action now, but in his opinion should go no lower. He said it was nothing to worry about. My question is: Is this seen as a terminal problem in terms of resale, or do most basses in this price range suffer from this problem? In reality, you can't really hear that there is a problem. And it does not hinder my playing.
