What are the big differences between an acoustic guitar amp and electric guitar amp?

[BubbaVO]

I've heard that the acoustic guitar amp can give voice to a broader frequency spectrum. If that's true why wouldn't you want that in your electric guitar question. Sorry to ask such a noob question.

A lot of jazz players do use amps and cabs that give an extended frequency response, its fine when you are playing clean. Play with distortion into a full range cab though and you'll soon find out why the natural high end rolloff of a guitar speaker is a good thing. It sounds like shit. On an acoustic amp, the extended high end adds "sparkle" to the sound with acoustic guitars.

Acoustic amps can sound pretty good with modellers though, since the modellers take care of the high end rolloff in their cab sims. I've used my Genz Benz Shenandoah to good effect with my AxeFx.
