Be one of the first to build our latest GBC 53 Marble Music Machine – a LEGO 42146 Liebherr Alternate model.
With this GBC you can really play music! Pins on the programming pins will trigger hammers which will push a GBC Ball over the edge to fall on the Xylophone Keys!

Monique Simon (Luxembourg) already tested the machine and created an original song! Take a listen below.
