Collings recently ceased using animal protein glues on their Traditional Series models, but this D2H T from 2018 was made before that change. Does it make a difference? We don't know for sure, but something sure makes this a terrific rosewood Dreadnought, maybe it's the torrefied top? One thing that probably hasn't made a difference is being broken in from playing, as this Collings doesn't look like it's seen much action and even the pickguard surface is almost perfect. If you check it over carefully under really bright light you'll find a small ding in the lacquer, next to the treble side of the fretboard, but that's about it for wear. Another plus, and it's a big one, is that this D2H T includes the Collings-made vintage-style case. That's another perk Collings no longer includes with Traditional models (but you can buy one from them, for $995, and the D cases are currently out-of-stock).
