Although I don't have a CWP, I agree with the other posters that it's probably the best for DEATH metal. Have a search for clips by Drac in Players... :)
Agree with MDV that the Painkiller would be an alternative - tight, powerful & handles detuning well.
Also, don't discount the Alnico Warpig - especially for slightly "doomier" DM ("Dreams of the carrion kind" by Disincarnate springs to mind). If you want Obituary-esque sludge, you could even try a Holy Diver (don't laugh).
But for proper Death Metal in the style of Suffocation, Malevolent Creation, Cannibal Corpse, Nile, Cryptopsy (sorry for the list of old bands, it's a long time since I bought all the DM I could lay my hands on :lol:) the CWP is the last word... :twisted:
FWIW, read the
sticky about the effects of different magnet types (including Tim's post about 4-5 down the thread about Ceramics).
