When Tom Petty says he won't back down, he means it. The "American Girl" singer was the victim of a guitar heist last week. According to TMZ, five of his vintage guitars were stolen from a soundstage in Los Angeles just days before his upcoming tour kicked off. But Petty and the police never gave up their search, and the rare guitars remarkably have been recovered. Following their disappearance, Petty made a public plea on Twitter offering a whopping $7,500 reward for the return of the pricey collection. Of course, the "Free Fallin'" singer had a back-up plan in place. Upon discovering his invaluable instruments had been jacked, Petty dropped top dollar on a white Gibson SG and a blonde Rickenbacker as replacements, TMZ is reporting. However, he may never have to use them. The man who stole the guitars has since been busted. Apparently, the thief was an independent contractor for the studio where Petty had been rehearsing when the guitars were taken. A rep from the facility issued the following statement, "We feel a real sense of responsibility for everything that happens on our lot and we have conveyed our profound apologies to Mr. Petty for the distress this incident has caused him."
