I'm in the market to get my first DGT. Things have boiled down to a 2019 with neck binding and a 2020 without the binding. I know that the 2020 has that new nitro over cellulose (cab) finish but it's not clear what finish the 2019 has. Is it poly, V12, or nitro? I has, as I said, the neck binding. And what about the pickups? I assume the 2020 have that newfangled TCI treatment. How does that affect the regular DGT pickups tone-wise? Unfortunately, both guitars are from online stores, so I can't try them first. Help me decide, please.
