Countless hours of use have worn a sizeable hole through the guitar's top, but because Willie refuses to have it repaired, the two of them continue to mature together. So protective of Trigger is Willie that only extreme circumstances can induce him even to temporarily part with it. When performing, he’s known to carry the guitar on and off stage himself.
And during his well-publicised kerfuffle with the IRS, he hid it at his manager’s office to prevent it from being seized. Trigger might nearly always be in Willie’s possession, but considering its long and storied past in music, I’d say it belongs to the whole world—just like the troubadour who keeps it.
