I'm a big pedal fan....the Iommi pickups are cool, but you can only use them in one guitar!! You can run all your guitars through a good pedal. With that being said, I have a Mentatone None More Black that is just awesome! Definitely gives you that high-gain sound, perfect for metal. I use mine all the time, to the point that my overdrive pedal usually just sits there. Test driving a None More Black is tough, though, it's hard to find a brick 'n mortar dealer. I just took a leap of faith with mine.
