I know there are a few people here who feel replacing pickups on a SBMM is a necessity, but I'll tell you this. I don't know a whole lot about swapping what's already there out for an Aquilar, but I have a Short Scale MM Stingray, and Short Scale SBMM Stingray, and the basses sound identical. If you're a fan of the Stingray sound and money is tight for you, ya might just want to think a bit more on this (if you haven't already). I've swapped pickups on other basses in the past and felt like just tossed money out the window.
