well they sound a hell of a lot better than the rio grande, just like all the BKPs
they do pair well together, Matt Bellamy uses a pair in his chrome guitar, it's just that by pairing one with a humbucker, you can get a much wider range of tones, i went for a Black Dog in the bridge and a MQ in the neck of my Les Paul, which gives me a ridiculously versatile guitar
