Firstly as rightly pointed out above stay away from AV3..they are the sweetest sounding low end guitars..i personally love those but definitely not for metal..
try out Cort EVL series....They are really good..
Else go for some guitar with stoptail bridge..Any Ibanez ..i wud prefer the RG or the Pacifica
And search on the net for some really powerful high output pickups which wud have ceramic or Alnico 5 magnet.
I guess deepsal has already mentioned Blackouts..They are really good..Not played on it personally..But have seen lot of videos and have read really good reviews on it. they seem really powerful.
U shud be good within 25max
