Dear Tyler,  Of course you should go to the Nationaal Museum van
Speelklok tot Pierement which is in Utrecht, a short train ride from
Amsterdam.  You can see it on the web at http://www.museumspeelklok.nl/

It is probably the finest mechanical music museum in the world and
has plenty of wonderful pieces, including lots of Dutch Street organs.
There are tours every day but if you communicate with them ahead of
time you might be able to get some personal attention including
a fascinating look at their workshops.

Have a good time!
