I think it's a Gibson 335.
Gibson brought out a Roy Orbison tribute model a few years back, but it doesn't look quite like the one pictured (note dot markers, not block). I guess he must have had a number of 335s over the years.
The Gibson ‘Inspired By’ Roy Orbison ES-335 Features:
Maple Top, Back, And Sides
Mahogany Neck With Long Tenon (1959 Rounded Profile)
24 3/4“ Scale-Length
