Yeah dude.,.,my good ibanez is an RG 7421XL.,.,.sumthing.,.,not a k -7..,.,but yeah its neck is wierd and takes some getting use to, but its worth is.,,.,.for the top (7th 6th 5th) srting i put thicker gauge strings on em to get a chunkier sound when i down pick.,.,and for the the four i use reg gauge.,.,.i use to tune my shit slightly flat(in standard).,.,like dimebag from Pantera.,.,so i could tweak the strings alittle better.,.,.but it made all of our covers sound sucky.,.,.ummm oh yeah.,.,if you get a seven string with the floyd rose bridge shit, say goodbye to ur whammy bar.,.,cuz it detunes you guitar and shit.,.,.which sux
.,.,.and it takes like an hour to tune it back up.,.,.but if you dont mess when the whammy, then you wont really have to re tune till a string breaks.,.,..,.,oh yeah.,.,.its priced at around a thousand$$.,.,.but i got my price cut in half.,.,which isnt bad.,.,.,i might want to check out those pick ups from emg .,.,the emg 7's.,.,.they'er made for 7 strings.,.,i dont know how they sound though.,.,
