I think most Gretsches are hollow but with bracing.
My EB-1 has three different endpins, (one being a screw in Schaller Strap Lock Stud). Does he recommend Vaseline each time? or only the first two??
Even the ones with painted on F holes? I remember the first time I saw a 'Chet Atkins'...about 50 years ago. Put me off the brand for life.
