Finally I've found difference by using iPad... Oh my poor sound card...
The answer is I LOVE ceramic Nailbomb, it sounds great! It absolutely is my favorite pickup compared with others, for me at least.
CS neck, Nailbomb neck, HD neck and MM neck, do you mates know sound characteristic of these?
Almost everyone suggests CS neck, but I wanna know how others sound.
Besides, some people recommend Trilogy Suite middle pickup as a replacement, is that a good idea? Most of time we use 2 or 4 position to play clean, is a higher output middle pickup the best choice?
