What's the best technique (short of getting a 4-string) for slapping on a 5- (or 6-) string bass and avoiding knocking the "B" string by accident? I rarely slap the "B" string. I understand there's some muting technique involved. I guess I have this problem 'cos I'm on a Stingray5, which has a pretty narrow neck as far as 5-strings go. But I've heard other bassists have a whack at it and I don't hear the "B" string get hit.
