Well I haven't really heard of Parker guitars.. so i have no comment there... but whenever the time comes for you to get a new guitar, i wish you the best of luck... ps: I strongly recommend Jackson guitars with XJ Jumbo frets... best control over fretboard. and Jackson, by my knowledge, make great 7 string guitars... i don't know if you've heard of a Shred Master called Rusty Cooley (exceptional guitarist)... well he uses a custom made 7-string Jackson Guitar... I'm saying that Jackson, to me, are the best guitars out of years of experience... well i've tried Ibanez S series as i told you... i also tried fender telecaster (definately not my type)... Yamaha Pacifica (not so bad) ... i've also tried Fernandez guitars (pretty good)... and yeah... i've tried B.C Rich's (peace of shit in my opinion) ... So Jackson is my top choice... by the way, Alexi Laiho of Children of Bodom used a Jackson Rhandy Rhoads signature series on his first 3 amazing albums... till his guitar was stolen if i'm not mistaken and then he had to make a new signature guitar for himself, so he signed with ESP. He shredded some major shit on these 3 albums while using the Jackson RR-1... mmm... one more thing... i hope i didn't bore you too much
... if you still think that ibanez guitars are the best choice for you, why not go for a Steve Vai signature series... GREAT guitars... there's also a 7-string Steve Vai Universe guitar... great Dimarzio pickups. Don't try a Satriani or Paul Gilbert series... i tried them once at a guitar shop and I didn't feel comfortable at all with any of them.... good luck with your guitar hunt
