There is the Kulmbacher Museum in Bayreuth, about an hour from Bamberg. There are quite a few options depending on how far you are willing to travel. I live in Vilseck, which is about 2 hours from Bamberg, or about 2.5 hours north of Munchen. I can suggest a whole lot of stuff, more than will fit on these pages. PM me if you want some more suggestions.
Always do sober what you said you would do drunk. That will teach you to keep your mouth shut. - Ernest Hemingway
