Once harvested for peanuts at garage sales and pawn shops—or free for lucky dumpster divers—the Silvertone Model 1484 Twin Twelve amplifier of 1963-’67 graduated to legend status over the past couple decades. Like a lot of ’60s gear with department store catalog origins, Silvertone amps and guitars provided great bang for the buck when they were new. But perhaps no Silvertone product—apart from the company’s Danelectro-built guitars—is as revered as the Twin Twelve. Mudhoney’s Mark Arm and Steve Turner discovered their charms early in their career, and Twin Twelves and their siblings remained backline fixtures for punks, garage rockers, and indie kids. But once the likes of Jack White and Dan Auerbach got on board, the market heated up considerably.
