The Strat in the Attic and its sequel are products of the age of “American Pickers” and “Antiques Roadshow,” but with a distinction: The author’s motives seem less about making a buck and more about the pleasure of discovery. Deke Dickerson is a musician and a self-professed guitar geek; as a member of the rockabilly Ecco-Fonics, he’s in a position to put that 1957 Gibson Flying V to good use. For 2, he collects many of his rare finds from folks he met as a result of his first book. He offers a tip for anyone who thinks he has valuables in his attic, basement or garage: “Sellers are commonly victims of bad information, sinister information, or no information at all.” The family from “Pawn Stars” would agree.
