The whole thing was made of silicon, as a demonstration of resonance and vibration at nano-scales. Harold Craighead, the director of the facility at the time described how it works,

A guitar made out of Lego pieces was sold recently on eBay. Click here for the pictures. It is a tribute to the Gibson Les Paul, with a P90 in the bridge position and a humbucker at the neck. Apparently it is fully functional, but suffers from tuning instability due to the weakness of the neck.
