Sometimes when I play my guitar, I think about how long my guitar will be around, and i'm certain it's going to outlive me.
Particularly when you have a nice american made Gibson or Fender. It's highly unlikely it's going to end up in a dumpster, or just break so bad its unfixable. And when you own more than one guitar, which almost all of us do, at least one is going to be around for a long time.
This is going to sound morbid, but when I was buying my epiphone sg/les paul custom, and the lady said it belonged to her son who died a year ago, it made me want to buy it more, so I did. It almost feels like someones guitar is a part of them. Like Jimi Hendrix's strat. That's more than just pieces of wood and electronics.
