Call prs and ask. I'm sure they will tell you. Make sure when you are looking for a guitar that it is in fact a 2020 model. There are plenty of 2019 guitars out there.
The 2020 models of the core guitars are relatively scarce.
I know they are rolling out the new finish and applying the TCI process across the entire core line. I'm not 100% positive on the timing of that roll out. I believe the first "line" of instruments to receive these changes is the 594.
