On page 10. The D'Addario advertisement. Is that a Music Man Head I see in the background ?

I saw that too (and you beat me to it...good eye!). I am hard pressed to figure out if that is an HD-130R head, HD-150 head or one of the 210 combos.
It sure looks like a Music Man amp to me, though, despite the lack of grill badges!
