After some time playing with the piece of wood inside, here are my impressions:

1. The instrument is noticeably louder, in a good way.
2. From the player’s position the sound is rounder and deeper. This is a subtle change, although it clearly sounds.
3. The instrument vibrates more with the sound, which is has a good psychological effect on me as a player (I also love that in pianos)

It may present a nice alternative for adding the benefits of wood to the instrument’s acoustic without changing its tight air chamber, and without compromising on the quality of the instrument (unlike Mylodica).
