This is a fun place to visit. There is a very cool collection of guitars from all sorts of rock guitarists on the first floor.
The museum has a good amount of history and then it gives you the opportunity to play a bit with things such as mixing the sound on a track and then getting on stage and dancing and singing.
It was not busy when we were there and you need one hour to get around it.
We had pre-booked but you probably don’t need to do this, since it did not provide any advantage.
