Notice where the neck joins the body! Also this instrument has no heel - so the neck is really accessible.
Last time we visited the workshop he was building a mermaid, complete with a guitar which you play by putting your arms around the mermaid - she also has sound hole in the side of her head so that the results of the performance are directed into the player's right ear. Difficult to describe or imagine I guess, but a stunning piece of craftsmansship when you see it in the "flesh", as it were.
