Not tried one myself so can't comment but I'm sure there's a pretty wide spectrum of sounds on tap with all those different coil combinations. All the switching options shown here are also parallel. I'm not sure why they don't offer series switching options as well.

More direct and punchy than the other coil combinations, some of which were a bit too scooped and polite for my liking. Who wants a 'polite' Stingray? Enough people to carry on making them I guess!
