Acoustic Amp?

[OctoberKIng]

Alright, picked up my new Ovation LCC047 Friday. Now it's time to pick up an amp. I don't know a thing about them, although I'm looking at a Kustom Sienna 30 Watt Combo Acoustic amp. So my questions are; whats a combo amp? whats the difference between an Acoustic Amp and a Guitar Amp?

whats a combo amp?
An amp where the the speaker and amplifier section are housed in the same structure.

This is unlike a "head", which is usually placed on top of a cabinet of speakers or speaker, also known as a "cab".
whats the difference between an Acoustic Amp and a Guitar Amp?
Musicians Friend had a couple good paragraphs I found-
Acoustic guitar amplifiers seek to project the brilliant highs of an acoustic guitar without losing the rich midranges and basses that make acoustic music so sweet. Distortion is exactly what they try to avoid. They usually allow a mic to be plugged in directly as well as providing an input for the signal from acoustic guitar pickups. Acoustic guitar amps almost always contain their own speakers which include larger bass drivers and small high-frequency tweeters.
Electric guitar amplifiers are generally the most sophisticated of all the types. Of course the universal popularity of the guitar has a lot to do with this. But just as important is the fact that a critical component of the sound most people want out of an electric guitar—a sustaining, rich distortion—comes from the amp alone.
