I just bought myself a new bass last week (Fender J), but it didn't come with the Fender case. The store threw in a free SKB case with the deal, but I noticed it has a weird, unpleasant (to me) odor; kind of a sickeningly-sweet, chocolatey/coffee kind of smell, I guess, pretty hard to describe. It probably wouldn't bother most people, but my nose is pretty sensitive, and it's actually starting to make the bass smell like it too. Any suggestions on how to get rid of it? Leave the case open and just air it out? Baking soda maybe?
