The painkiller has more treble than the nailbomb for sure.
I think the painkiller would nail necrophagist etc but but the nailbomb better suited to Opeth, DT etc and beyond to be fair.
For me I think the ceramic nailbomb is the best bet here. The nailbomb is a lot more versatile than the painkiller and is for recommended for prog metal to thrash. If the tech death stuff takes primacy though then go for the painkiller......the painkiller sits some where between a duncan distortion and an emg 81 but with lots of 'grindy' character and much more clarity than duncan or emg. The painkiller for me covers judas priest painkiller tone and beyond and is not suited to the mellower moments of say DT, Opeth etc.
Ok, Jimmy, thanks for your recommendation. Now I'm even more indecisive. I love the Necrophagist tone but If I had to choose between that one and something more versatile like DT, Opeth, and all that stuff, the decision is tougher. I bet someone told me the Nailbombs are even brighter than the Painkillers
Tone is subjective and I was being diplomatic but as a matter of fact the Painkiller is certainly brighter than the nailbomb and who ever told you otherwise is plain wrong! As Eric rightly says the nailbomb is warmer.
Have a think about it but I think you'd be happy with either. The nailbomb is often recommended for trash and progressive metal styles so logically if it can do progressive stuff and thrashy riffs it'll be fine with tech death! For riffs and in the right guitar the nailbomb is my favourite rythm pickup of all.
The ceramic nailbomb and painkiller wont be worlds apart. If you're really happy with the voicing of your amp in general i'd go for the ceramic nailbomb. If your amp is severely lacking in terms of tightness/high mids/treble then i'd go painkiller.
Both will be awesome but I think the c-bomb is what youre after. Thinking about it you have similar tastes to me and thats what id use!
