I think ceramic warpig or painkillers. if u downtune, don't underestimate painkillers, amzing mid punch for death metal and NOT too bright for your alder guitar, I've had brilliant results in an alder ESP sv. They're more modern sounding than the C-bomb which retains it's PAF character and has thinner lead tone. Listen again to clips of painkillers and especially ceramic warpig, i've read many reviews saying this KILLS in alder.
