Im used to play 6 drop c but now im going to buy a really nice 7 string guitar! thinking of an ibanez j custom... Ive played 7 strings a bunch but I have never experimented with pickups on them... I know the nazgul and black winter are good 7 string options... any others? I play technical death metal/death metal/melodic death metal.... Anything heavy... I like my high strings to not sound overly piercing but I want the low strings to be extremely tight and crunchy sounding... with some grind for trem picking...
