To make a long story short, I got a Fender MIM Standard 5 as my first five-string. I couldn't be happier - I managed to get one fresh out of a factory box, without the grungy fingerboard and 1 inch string action of typical off-the-wall models. While the tone is satisfying as is, the single coil pickups hum even when you roll of one a tad. I recall reading somewhere that MIM 5's have non-standard pickups sizes. So my question is two fold - is it possible to replace the bi-pole pickups in now, and are there any recommendations for a "noiseless" replacement pair?
