I agree pentatonic, there is always a misconception that low-medium output pickups cant do metal. Well after taking advice from sub, now i am using seymour duncan 59' and dimarzio air norton on my ibanez s670se to very gd effect, lots of overtones, warmth, harmonics, control and chug to some extent haha! With this combi, i can pretty much play any genre of music from blues to prog rock and metal lol!
But if EMG gets the sound that u envision in ur mind then by all means get them, although i would suggest that u hear more sound clips or better yet try out ur friend's axe with EMGs to hear the real deal, cheers!
