the riff raff has been my favorite bridge pickup for years
but I think I liked the vhII slightly better in my SG special
it's a bit hotter, punchier and less mid loaded, and I think that fits the SG a little nicer, although I like the riff raff better in les pauls
the mule also should sound absolutely amazing in sgs, if you want a less spanky sound, with a more chewy gain
