It looks like the classic Fender Lead I. It's a really old and discontinued guitar similar to my Lead II.
Im pretty sure that's his fender bronco! They're pretty hard to come by now form what i can gather

Fender Lonestar Stratocaster w/ Seymour Duncan pearly Gates!!!
PRS SE Custom 24 Vintage Natural
Gibson Les Paul Signature T Trans Ebony
Engl Screamer 50
if you could find a mustang it would be fairly similar
