Re: 'S' vs. 'RG'
i've owned an s550ltd, sc420 (think that's what it's called) and another s470 (with a standard tz trem). i also own(ed) rga121, rg3120, rg550, rt650 and numerous rt450s. body woods on the s guitars have been basswood, mahogony and alder, same as the woods on the rgs. and they all have (at least initially) featured either ibz/dimarzio pickups or the v series. my conclusion is that the rgs just sound much better. i think that the lack of wood on those s bodies do not make it conducive for generating full bodied tone. i'm sure others will disagree with me, but i've had plenty of experiences with the s guitars and i've yet to be surprised with a full tone. the rgs on the other hand, are workhorses. they usually sound fairly decent with just the stock pickups (at least the rt450s & rga121 do) and resonate better when played unamplified. now i'm sure you can make the s guitars sound better with a change of pickups, but any guitar can be made to sound better with new pickups. if we're talking about the inherent quality of the guitar design, i'd say the rg is the hands down winner.
