Since the introduction of Emulators, a many problems have been illuminated. Before Emulators, musicians were stuck with a particular guitar or amplifier. Even if you were a mega rockstar, you were probably stuck with one amp. Emulators changed all that. Now emulators can give the effect of many Amps and combos. But that is just the start. Emulators can turn your Electric Guitar into an Acoustic Guitar. Or maybe a Synthesizer or Organ.
