I think I got interested in this for a simple reason : when you play solo fingerstyle, you try to play several instrument parts in one... but there's one missing, it's percussion. I just have this piece I talked about some time ago, "The discovery of Avalon"
and there is a middle part that is faster with a lot of strumming. I wasn't really happy with it and thought some drum-like percussion would spice things up... but a cracked top is not a price I want to pay for some experimental beating on an unfinished piece ! So John, no it ain't so anymore
... thank JB for it... But I may find a softer version of Eric Roche's big bass thud
This reminds me of a concert of the Japanese player Isato Nakagawa in Belgium. He hits the top and sides on some of his pieces too, and told the audience that it's something he never does in Japan, because his wife might hear of it. He had smashed a top once and came home with a broken guitar. "Isato, stop this!" his wife said, "a guitar is very expensive!"
So from then on he does it only far away from home...
