There are not too many differences in these guitars. *Mainly, the binding, as you mentioned on the Standards and the colors. *Pretty much just visualization differences. *But there is a quality issue with the Studios too. *I've seen one or two cross my path that were excellent players, but most need lots of care to get them in a players condititon. *Standards are a bit better crafted IMHO - more attention to details of the guitar at the factory so it seems. *I believe these even have the same pickups - the 490 and 498 and the same wood.
I like the looks of the Standards much better than the studios.
The SG's are a completely different
sounding guitar. *They're screechy and tend to feedback a bit more than LP's. *They have a bit higher-end tone. *I feel the LP has a bit more full 'ballsy' sound than the SG, but both are fine instruments. *The
neck joint on SG's are fragile and have been known to crack and break when dropped or abused.
