Yes, it’s metonymy, as people have said. You also get it in similar contexts where people will name a building such as ‘the White House’ or ‘[10] Downing Street’ to refer to the governments of the US or the UK.

I can’t remember who wrote it, but there’s a short essay by a Japanese noise rock artist (maybe Agata from Melt Banana?) on ‘How to be a guitarist’ and it basically says ‘Get a guitar. Tune it if you like but this isn’t necessary.’ So, yeah: that’s about where I’m at on the question.
