Perhaps his most oddball guitar, the "Bona-bird" was commissioned by Bonamassa because he dug Firebirds but they tended to be neck heavy. It combines a reverse Firebird neck with a Les Paul body with just a single humbucker in the bridge. He says, "The jury's a bit out on the aesthetic of it, but I actually dig it." The guitar has an angry, growling tone. Bonamassa used the guitar, capoed at the second fret for singing, on “Slow Train.”
