Thinking about getting my first acoustic and have heard good things about the Alvarez AD30. Been playing electric for awhile and feel the need to switch it up a bit. Was wondering if anyone with an Alvarez could give me some insight and opinions on them. Thanks
I'm not familiar with that particular model but Alvarez have a pretty good reputation across the board. From their entry level stuff all the way up to their expensive Yairi models they are competitive with similarly priced guitars from any brand in my opinion.

I personally own an MD90 and am very happy with it
I own a couple of Alvarez guitars and I like them. Good value and they play well, although I can't say much of anything about their artist series as I've only played a couple of them while browsing a few stores, but I recall they played and sounded fine to me.
