A bit too far for a day out - it's 4 hours drive each way. I was there in 2011. There's a superb instrument museum there. But virtually no english. By chance we arrived on the museum's 'open' day (it's open all year round). This meant lots of really interesting people to talk to and guys working. Nice concert in the afternoon as well. It's declined a lot since the pre WWII heyday - especially with the level of nationalisation & state control that went on in the post war years. Not too far over the Czech border is Kraslice, where Kohlert and Keilwerth were based, but there's little to see there (drove through on the way to Prague. Very run down).
