I have both- 03 Standard with 60's neck and 98 classic plus-plus refers to top only.....necks are almost identical...the standard, in my case is sliggghhhhtly slimmer....my classic is heavier,but other than that...
1. inlays-classics have snot green inlays..some like/most hate-mine isnt very bad and it sort of goes with the amber top
2. the pickups-classics come with ceramic hot pups.....just replace with bk's!!
3. some classics have the thick binding in the cutaway,acc. to the year
4. BRIDGE-MY CLASSIC HAS ABR-I PREFER IT
-having owned both, I would say they both are killer-you can score classics at lower price, so they are killer deals-i love mine(it haS UNPOTTED MULES....YES!!)
