well it was that good, it has been that good, but as they scale up volume you know it won't stay that way, like PRS S2 beveled Kia garbage.
the tone is quantifiable in sustain and resonance, it all boils down to very minute techniques in how base materials are treated (dried) and assembled (press fit + glued), and the resulting vibrational transfer through the whole assembly. ie cnc tolerances, and how much resulting pressure is holding in the frets, the nut, the tuners, the neck pocket. you don't get that tone out of warmoth or Gibson stuff for one reason, there's basically not a much mechanical pressure between materials. ESP Japan, kiesel, Anderson, Suhr, all share a resonant characteristic, from two things in common, wood dried out extra crazy and sealed up, and components assembled tight af
