well, i wouldn't ever smash an instrument !
every instrument is unique:
- it's set up perfect because you played it for a long time, searching for the best way to set it up
- it's got stories to tell (like forest gump's shoes)
plus: why smash such a beautiful thing ??
seeing a nice instrument beeing smashed does feel odd. maybe i wouldn't wince seeing a mass production factory-bass (made of agathis or other frequent cheap woods), but i would call it a horror movie, seeing basses being smashed, that are built by real humans, who love what they do, and therefore use only the finest ingredients.
(for the luthier, it must feel like watching his ex-girlfriend fuck another guy)
but like i said: it's just my opinion. slipknot doesn't behave in a shocking way since yesterday, so it's not very surprising, is it ?
perhaps some would call it a horror to see mojoed instruments (thinking: why doesn't the owner take care of his instrument).
you see, it's like the german saying:
"opinions are like buttholes: everyone's got his own"
and that makes the whole thing run the risk of being an endless discussion (like diabq said before)
p.s.
many say that the thumb has that "in your face"-sound.
so, wouldn't you hit someone back, who's punching in your face ?
;-)
(just kidding, of course)
