Porter muses over the highlights of his vast collection used on records by everyone from B.B. King to Eric Clapton to the Smiths.

"This one-of-a-kind guitar was built to Porter's specifications by Gibson's master builder at the time Roger Giffin, in exchange for a tweed Fender Bassman. Porter laughs when speaking of the deal," I handed him a pair of P-90s from a 1952 Les Paul and told him I wanted an L5, but at the scale of a Les Paul. There is no other guitar like this one."
