well it's korean made, 22 frets, lo trs2 trem or Zero rocker trem(2003 models)
22 frets- comes down to personal preferance, personally i love those extra 2 on the 24fret necks because even if you still only go to 22 you have much better, more comfortable access
if you use the trem a lot you really don't want the lo trs as it's weaker cheaper and less stable
i have no idea what the zero rocker is like
the ibanez edge and lo pro edge are awesome
and are standard on the (before 2003) higher model s series,
jems and Universes and RG5xx and higher
also ibanez pickups tend to be crap so you may want to consider changing them
some(signature models and others) already have custom dimarzio...etc
pickups anyway
as for being korean made, made in japan is much better(quality and attention to detail and just feels nicer)
but the korean guitars are still very good
japan made guitars include RG5xx and higher, jems, universes and many others
personally i'd look for something better
for $325 you could get a nice RG5xx
actually i'm in the process of buying an RG7620 for $300 at the moment
and before i decided whose to buy i had about 5 people offering me
RG7620s for between $300 and $400
incase you don't know the RG7620 is a japan made, Lo pro edge equipped
7 string
hope it helps
