I have recently got new Era 1 and very happy with the sound. It was tested on my Taylor acoustic Guitar and Music Man JP Majesty. I didn't try all features yet. In General I have bought it to have very good clean acoustic sound for recording but it is also very useful for some concerts. Maybe about 1 thing I have to mention what I not really like but maybe it is natural thing: the noise from amp. When you put Volume on 12 o clock and gain parameter also about 12 o clock it is getting markedly , but it is also possible to play with the parameters to reduce the noise. The conclusion is: clean sound itself just fantastic, exact what I expected. Number of effects is enough and can be customized, interesting work of EQ with boosting the frequents. In my opinion it is great acoustic Amp!
