Total wankadoodle behavior fershure and if the premise was to have the actress believe it was a priceless relic they could have given her another guit and just SAID it was the museum piece.
Still... this stinks a little of some product placement/marketing shenanigans.
Outside of guitar players/music oriented folks who would really know about the Martin brand (which is obviously a very nice brand)? Conjuring up some wacky Hollywood shenanigans like this could plant the name into the minds of laymen who'd otherwise go "durr... I done heard of teh Gibzins and thuh Fendarz... Imma gunna get me one of doz to play at the campgroundz".
The outrage from real guitar players about a priceless Martin getting destroyed just adds to the hype/branding.
If it was staged... pretty clever branding.
If it wasn't... this will only be good for Martin's sales so no loss to them.
Either way... for us guit hounds, definitely a cringe worthy event.
