I replaced the Dimarzios in my main seven string- The Ibanez RG 7620 and installed a pair of Seymour Duncan Distortions. the bridge has amazing bite, no muffled tone when I'm tuned to A, just ****ing great for metal but it does have a decent clean tone. The neck is not as much as a monster as the bridge version but I'm just loving the clarity, every note just screams when sweep picking. The only other neck pickupd I would consider would be the Seymour Duncan Pearly Gates. Gah! I'm seriously loving these pickups. I love them so much I think I'm gonna install some on my six stringers too. TRY THEM OUT!
Furtado's has a crappy selection of pickups. Deal with Alberto's, they'll get whatever you need, and you can bargain with them.
