Jerry Jones Baritone (?)

"The first note you hear on the album is this Jerry Jones Baritone guitar, based on the old Danelectros. It's that 'dert-dert-de-de-de-dert-dert-dert...' thing and I'm playing harmonics all the way up the neck. But I've got a problem, because it's tuned down to A, so I'm playing the B on the bottom string, but I don't know how to do it live on a normal guitar" (Gary Moore)
