I have a second Kala Elite Doghair 2019 build (don't ask) and it sounds almost exactly the same as my first one but slightly louder. What a screamer! I've also played one they had in stock at HMS and it was louder than average as well. I didn't buy it only because it had GraphTech Ratios installed and two of them were already broken (hence a direct buy from Kala). The only vintage Martin I've played recently was from the late 1950s and was on the soft and dull side but the owner, my student, kept really thin nylon black strings on it (almost as old as the instruments!) so it probably could sound much better. But, yeah, the Doghair doesn't sound like Martins I've heard.

I'm sure the tone will eventually mellow some as I've only owned it for a little over a month.
