I've heard others say that the neck profile is identical between them, but my 70s feels thinner front to back. It might be an optical illusion due to the binding, but it feels like a different profile, IMHO. I haven't measured to verify though. As I mentioned previously, the 70s was built in Indonesia, the 60s in China. (Both 2022 models). My 70s is DEFINITELY lighter. Aesthetics and woods aside, they sound nearly identical to my ears.
