Thanks for the great discussion. I've had two guitars with Truetone for almost one year. Both are TC Alpine models, which are very light for TC models, which is what was driving my color change questions. After a year, I haven't noticed much of a change, but these things are gradual anyway, so it's hard to tell unless I compare my NGD photos to now (and even that's subject to lighting consistency). Now, I've gotten the AC622CE, which is Euro Spruce and non-TC, so I expect to see and notice the color changes more easily.
As for the finish itself, I had a difficult time noticing the difference between Nitro on my other guitars and the Truetone on these newer models. They seemed similar to me, although maybe I noticed some difference on the necks (they seem less glossy). All three guitars are very responsive, but so is my 2019 E10OM, which was the last new guitar I purchased before they switched finishes.
Bottom line: I can't tell much of a difference between the Nitro and Truetone finishes, which is probably a good thing, if the Truetone holds up as well or better than Nitro, in terms of protection, avoiding cracks, chips, scratches, etc.
