The guitar destroyed by Kurt Russell’s character was not a prop
but an antique 1870s Martin guitar lent by the Martin Guitar
Museum. According to sound mixer Mark Ulano, the guitar was
supposed to have been switched with a copy to be destroyed,
but this was not communicated to Russell; everyone on the set
was "pretty freaked out" at the guitar’s destruction, and actress
Jennifer Jason Leigh’s reaction was genuine, though "Tarantino
was in a corner of the room with a funny curl on his lips, because
he got something out of it with the performance."

Museum director Dick Boak said that the museum was not told
that the script included a scene that called for a guitar being s
mashed, and determined that it was irreparable.

The insurance remunerated the purchase value of the guitar
and as a result of the incident, the museum no longer lends
props to film productions.
