I have a Peavey Grind NTB (4 string) that I'm looking to upgrade the pickups in. I know there was someone who did just this, I think they put some EMGs in a Grind. I remember reading that thread, but now I can't find it! So my main question for this person would be what pickups fit in the Grind. Does it have an irregular shape compared to most pickups? The tone I'm looking for in this bass is a fat, growly, but still defined tone. Sorry if that's a wierd description. What pickups are best for this?
