Classics basically are standards, just with different aesthetics, slightly hotter pickups, and different inlays
I disagree with the kid, for at least the brand new stuff I think the classics are much better looking than a faded diarrhea burst standard.
Just like all gibsons, the weight varies. If you're buying new, buy it from somewhere that lists the actual weight of the guitar you're going to get, because it can be anywhere from 7-9.5 lbs.
And I was surprised at how functional the circuit board is - I'm sure eventually it will shit out and ill replace it with 50s wiring, as I normally do with LPs, but it does sound quite good.
Basically, I would choose between a standard and a classic based on the color/aesthetics you want, because all of the other stuff is modd-able or inconsequential. The QC has gotten a lot better with gibson the last half decade, too.
