HI Guys!
I bought a Gibson ES-175 used in So Cal in the late 80's. Based on its serial number Gibson customer service dates the guitar as 1970-1972.
I have done nothing to modify it, but don't know if the previous owner(s) did anything. My question has to do with the tuners. I always thought they were original because they say "Gibson"...but who knows. It does appear to me now that most of the 70's ES-175's I see online have very different tuners...I guess they are a Schaller tuner marked with the name "Deluxe" and "Gibson" on them. These style tuners mount to the rear of the head stock via two screws, one at the top of the tuner, one at the bottom.
My tuners appear to be a Grover tuner embossed with "Gibson" on them and mount to the head stock via a single screw set to the inside of the tuner body. Importantly, I see no evidence of patched screw holes. Seems to me that if these tuners were replacing the Schaller OEM tuners there would have been at least one, maybe two screw holes to patch. I see zero evidence of any patchwork having been done.
So, here's the question: Could my tuners be OEM?
