my favorite single coils for strat sounds are the rio grande vintage tallboys and fender 57/62's. i go more for a slightly fat vintage sound with my singles, though. i have a set of virtual vintage blues in my 540R and the extra beef in those pickups were needed because the basswood is so unlike ash or alder. in truth, ibanez does make a killer single coil for basswood in the S1. lots of output, fat tone, and plenty of sparkle. these pair up well with many humbuckers and sound good while doing it. i have several duncan singles as well: vintage staggered, vintage flat, custom staggered, custom flat, the hot for strat. all sound great, but the most unlike a strat single is the hot for strat. luckily, i have that paired up with a duncan 59 and distortion in my rg550, so it plays very well with those. i wouldn't want a guitar loaded with just those...especially going for more of a vintage vibe.
