Never shipped a Bass there, but I work there and have taken them across. Depends Where it has to go in Germany, but some flights are silly money £36 return inc booking fees. Might be easier and more reliable to book a cheap flight, take it as hand luggage, meet your man/woman at the airport and get a flight back out! Better still have a night on the beer there and come back the next day!
Sorry I can't be more help on shipping costs.
