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 hard-to-find model was Gibson's first-ever cutaway flattop, and the first flattop with a pickup. Porter found the guitar held together by house paint and the folks at Voltage Guitars in Hollywood refurbished it in gold. It's a great songwriting guitar," says Porter, "and it's been on every record I've made in the last 15 years."
