Re: best passive pickups for death metal?
Duncan's: Distortion, Full Shred......that's about it if you really want to go Brootal
Dimarzio's: X2n- amazing for death metal, i have it in two of my RG's and it really hits your amp with the heavy punch needed for death metal.
EVO- great for a more complex sound than the X2n, not as hot but still has an awesome edge to it.
D-sonic- GREAT if you have a very nice amp. it has a beautiful tone but a lot of your power is gunna have to come from your amp/stompboxes, especially if you're playing death metal
