Welcome to the official Billy Corgan Reverb Shop. Over 100 pieces of gear that Billy Corgan used to craft sounds for recordings and tours — the pre–amps, heads, combos, guitars, basses, and more — are now available for sale. You'll find everything from a drum machine used on pre-Pumpkins demos, the Siamese Dream and Mellon Collie amp rigs, prototype signature Fender Strats and other collector-grade vintage guitars, and so much more from Machina to Zwan.
