Just now saw this! To be honest, I was born in '72 and my LP Custom is a '71, but close enough for me. Still feels like it's from my birth year and it's a hell of a conversation piece. Not to mention a killer playing and sounding axe.
Anyway, it's my belief that the late '70s and early '80s guitars are the next to jump in price. It may not be for 4-5 years, but they're next. So what I'm saying is that if you really want a guitar from your birth year, I'd jump on it. It will keep going up and up in price as the years go by.
Plus, those silverburst LPs are highly sought after anyway, which makes it even cooler! Heck yeah, I'd do it in a heartbeat!
