A friend of mine put one of those in a Melody Maker, as that was a one-pickup guitar, and I was surprised at how many different sounds he could get out of it. While the P90 is a single coil, it's not like any other single coil you might be familiar with, including the one in the same package, so you basically get two substantially different single coils in that package. Then, of course there's the humbucking mode, which is substantially different again. Then, for each of the basic modes, you have the full-tilt boogie sound, then the slightly backed off sound where it cleans up. If you have a tone control wired in, there's another filter for you. All in all, a lotta different sounds out of a simple hardtail guitar with a single pickup and very simple controls.
