A central part of the soundboard can be removed and swapped for one of many different chunks of wood to alter the signal generated by the pickups.
Interesting approach. From what I gather, change the guitar tone using sound board sections made from different types of wood and software processing to create a "virtual guitar body" with varying tone characteristics. He mentions using different materials (plastic, concrete) to create completely new guitar tones.
