Mark Knopfler, told to Guitar Player in June ’92Sounds like one "latest trick" to pull, Custom Shop!
“My Les Paul has a little alteration. You can pull a pot up and get a slightly out-of-phase sound. Then you just back one of the levels down a little bit to where it becomes this voice. I always liked that sound; with a Les Paul it’s a beautiful thing.”
Meanwhile, you can also read that other post by Gibson on a Les Paul struck by lightning going for auction on eBay. It's a 1985 Reissue. Knopfler's was a 1984.
