Your instrument is everything to you. You worked hard to afford your acoustic guitar and pamper it like a lover. Understandably, when it comes to amplifying your acoustic instrument you don't want your sound to be touched -- you want an amp that is totally faithful to your instrument and your music.

Quality:
Too early to tell about reliability, but it sure is pertty.
Value:
You can get much more expensive acoustic amps, but dollar for dollar it's the best I've heard.
Sound:
I owned a ACX 1000 behringer before this, and the 1800 is so much better, it's like night & day. Behringer really did a good job of taking out the noise which was the big complaint of the ACX1000. The sound is so much cleaner.
