A friend I met at some jam sessions was using the A20. It sounded so much better than any I had heard when attached to acoustic electric dreadnaught. I played my Martin 0015 thru it and really liked the sound. Stopped by my closest Guitar Center (OKC) and lo they had one new in box, but none on display. I asked the sales associate about the reviewed hiss/noise problem. He indicated had not been a problem before at this store. It just happened to be on sale, so I bought one. My Alvarez also sounds great thru the A20.

I am certainly not a pro but can't imagine getting a better acoustic amp for this very low price. (I have not yet used A20 for 20 hours, but have used at home and at two different jam sessions. I simply don't hear the noise or hiss other reviewers warn about.

Was looking for a smaller acoustic/practice amp for home use and when it arrived I was really pleased - nice construction, aesthetics, design, good looks/good fit...but has a VERY loud background hiss even at the lowest volume levels. I realize this doesn't have a dual Master/Channel volume set up, but the background noise was just so loud I had to return it. Tried a 2nd one out of the box - same thing. I also went to the local GC and tried out other similar-sized/priced amps, all of which had considerably lower background noise. If you play all loud, all the time then this might work - but any quiet interludes will be taken over by loud background hiss. I hope Acoustic can fix this - if they can, I'll pick up one (or two). If they can't then it's honestly just not ready for prime time.

      Comments about A20 20W Acoustic Guitar Amplifier:

      Have used the A20 in small clubs and larger events using the built-in XLR DI output. The 8" speaker with coaxial tweeter delivers full-range, high-fidelity sound that replicates the acoustic instrument's natural timbre. Having a tunable feedback filter exceeds the price of this amplifier, along with 3-band EQ and chorus and reverb allow one to dial in the sound and eliminate feedback. With two combination XLR 1/4" inputs, one can use a variety of instruments and microphones for the individual situation. On a side note, we have used this an a bass amplifier for electric bass, with surprising sound.

        Comments about A20 20W Acoustic Guitar Amplifier:

        I do a folk and gospel music sing-along ministry and I give guitar lessons at home.
        I bought my Acoustic A20 almost three years ago. It has gone with me on almost every gig I've played.
        My venues are cafeterias, nursing home day rooms, social halls, meeting halls, church sanctuaries etc.
        It is not powerful enough to handle a very large hall or a large church sanctuary or an outdoor venue such as a company picnic or an outdoor concert.
        This combo amp has proven itself to be a reliable work horse for me.
        I only wish it were a bit lighter to carry.
        I have previously sold my Line-6 combo amp and my Fender combo amp, but I'm keeping my Acoustic A20.

            I got this for my wife for her birthday. She plays classical, and said she didn't need an amp. After a couple of weeks, she said, ya maybe an amp would be good. Being a drummer, I went on what the salesman at Guitar Center said. My wife was very happy with the choice. It's great for practice, and smaller jobs, but you can get good volume, and effects from it too. It has good depth, and a warm sound, and makes a box guitar sound full and clear. Thank you Guitar Center for your help!!

            Comments about A20 20W Acoustic Guitar Amplifier:

            Was at my local GC checking out the acoustic amps in stock and came across this little guy. The size and price first got my attention "it was on sale and I had a gift card." I plugged her in and I was surprised with a nice clean sound and the two built in effects. This does not compare to higher end acoustic amps, but for a small amp to use at home or for a very small venue its perfect. I have read negative reviews of this infamous loud hissing but I havent noticed any of that? All and all, if you want a small value amp for practicing or playing say a coffee shop this would work just fine.
