I just bought a fairly new used Stingray and, to my horror, have discovered a gap between the neck and body where they meet, as if the neck pocket is too big. The gap is big enough to slip a business card into. Now I'm assuming that Musicman basses don't leave the factory with such a flaw, so can anyone tell me what's likely to have caused the gap, and if it's fixable. Getting a refund isn't an option, so I'm hoping someone has a solution. Thanks.
