I was wondering what the main differences are in sound with a HSS pick-up configuration versus a HH one.

with HH you can get the sound of two humbuckers together, which is more powerful than any combination on a HSS guitar (with standard switching config)

and (obviously) you can only get a single-coil sound on a HSS config, unless the humbuckers on the HH have coil taps
