Well....lacquer certainly ages more quickly and therefore leads to mojo more quickly. Poly, on the other hand, withstands abuse and age better. I guess lacquer probably has more fans on here...I don't know, though. Both of my Gretsches -- a Stephen Stills White Falcon and a Chet 6120 -- are poly, and I love both of them. I think in the end it boils down to how you respond to the guitar. It obviously doesn't influence sound, so it becomes a question of surface beauty. The way I look at it: when you're playing a Gretsch, you're already ahead in the cool beauty zone, so it winds up being a question of how fast you want the mojo to settle over your guitar. Welcome to the forum, by the way!
