Feature:
I plugged a second instrument into the mic channel and though that might not be the intended use, it works very well and sounded great.

Quality:
This amp seems to be pretty rugged like the old Fender amps were made.

Value:
I did alot of research before purchasing this amp and although there were cheaper amps in this category, this seemed to be the best quality for the money.

Sound:
I have tried this amp with my Ovation 12-String, mandolin, and two different resonator guitars. I was able to quickly find the sound I wanted without alot of fussing around. This amp produces a very natural warm sound. The highs are clean, but not brash.

Support:
I want to purchase the optional 2-button FX footswitch, but can't seem to find one. It isn't even listed (as far as I can tell) on the Fender web site. I contacted Fender (e-mail), and they said someone would get back to me in two-weeks or so...not exactly responsive. So far, this is the only complaint I have.

Overall:
If someone stole this amp, I would have to get another. This is the best my accoustic intruments have ever sounded in a live environment.

Feature:
How many acoustic amps offer this kind of variation in effects and eq, not to mention the optional Mic input, which sounds great. This amp has it all in one efficient little package.

Quality:
It seems pretty solid, the sounds quality and the components seem pretty good, I have been looking at this amp in store for several months, and when I got it home to have a closer look, it was all pretty exact to the specs, so you're not getting let down if you read up on this amp and know what you're getting into.

Value:
I really expected to pay a lot more for this amp, by the time taxes got to me, I was paying almost 2 grand for my Supersonic amp, mind you it is a tube amp, but still, to me this is easily and equal quality amp for its purpose, so I would have paid more if I had to.

Desirability:
Ive got this setup usually a few feet away from my Supersonic when playing... that is one sexy combo :p.

Sound:
I play through a Godin XTSA in the acoustic input, and use a diamond compressor so draw out the sring definition... wow. The combination honestly sound better then most real electric acoustics. The clarity and versatility of the acoustic sound on this amp is unbelievable, I was floored.

Ease of Use:
Like most of the other reviewers on here, I would like to be able to find a good working footswitch for this amp, but not such luck so far, other than that its a pretty straight foreward amp, plenty of options without any complex lingo, and I like that.

Support:
5 Year warranty is killer, but give me a foot switch !

Overall:
Couldnt ask for more, this is top notch, Ive been experimenting with various amps for a while, but I dont think I can get away from fender amps anymore, and this one just has me hooked. Ive tried a few others (roland, behringer,etc), and they just dont stand up in terms of quality and value. This amp is going to be with me forever. Theres nothing more satisfying than buying equipment and knowing its a permanent part of your setup.

Feature:
I like the expanded effects (DSP model) but I wish the footswitch (optional) had a control feature on it to select effects. You must pre-set the effect prior to the song and turn it on/off with the footswitch. The effects are better than original, but still not 100%. Choral, reverb, virbrato, delay, and multiples of those. I would love to have a fuzz just for kicks.

Quality:
great workmanship and good quality. I love the amp and wouldn't use any other brand for my acoustic guitar.

Value:
The original at approx $375 was a great value, but the DSP is about $475 and that is a little too much, given the extra features. I think $400 - $425 (internet pricing) would be a better value. The higher price may price it out of the market for some people. I was fortunate enough to buy a "blemished" model for a little under $400 and if it weren't for that, I probably would not have sold my old one and purchased the new one.

Desirability:
Very well known product.... Easily recognized as the premium acoustic guitar amp. Very sexy.

Sound:
First, I purchased the Acoustasonic 30 a few years ago. It was a great amp, but didn't quite have enough power for me so I sold it. Then I purchased the Acoustasonic Jr and loved it and used it for several years until I sold it to buy the DSP model last week and it sounds just as good as the original. Great for acoustic guitar and microphone, also, though I rarely use it with a mic. I have pushed two acoustic guitars through it though and it is a fantastic amp. Great sound. Easy to use, rarely have to set volume past 3 or 4 and if you send it through to a sound system, you don't need to push it more than 2 (and use it for a monitor).

Overall:
I don't think I'll ever replace this little baby..... Unless I go to the SFX model way way way in the future.
