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.

Below are two reviews out of five that mentioned hiss from the amp. Unfortunately, I ignored the warnings. They are correct. I received the amp today and before plugging in and with all pots cranked left (off) as they are right out of the box, I powered up to hear a very audible hiss. Not good. This is not a 60 cycle hum and has nothing to do with bad power or ground loops. It is amp hiss which cannot be rectified.

I bought the amp to place in front of my couch pointing at me to practice at low volumes with effects. My ears are bothered by the constant unclean sound at these low volumes. If the amp had a mic on it for stage work, the hiss would definitely be heard when not playing and possibly within the music.

I am disappointed at myself for not taking those reports seriously. I did so because I trusted the brand and because the design of the amp seemed perfect for my needs.

The amp otherwise is really sweet. The effects are usable and the EQ is very sensitive with fantastic range. It also delivers brilliant highs and soothing warm low end. It is a powerful 20 watts and my baritone ukulele sounds wonderful through it. But the hiss ... it never stops. It is never clean even with the volume off.

I really wanted to keep this amp, but I will be returning it and looking towards a Roland or Fishman both offering higher wattages which I do not need, not to mention the much higher price points.

The experience is a bummer but I have faith in MF's return policy and honest service.

Good acoustic amp for the money

Comments about A20 20W Acoustic Guitar Amplifier:

Bought this for the wife to use with her electro-clasical. It does have a bit of hiss, but not too bad. Neither of us like the chorus, but the reverb is okay. The amp itself does a nice job with her nylon-strung guitar.

Purchased online for practice amp or backyard parties Very impressed with volume, tones and controls. Mic input is nice and the PA control
on back panel is a bonus. Works great with Yamaha FSX800C, can also use for practice with epiphone les paul for a clean tone. Purchased wth Guitar Center 15% coupon for a great price, very happy.

    Comments about A20 20W Acoustic Guitar Amplifier:

    This Acoustic A20 is a great amp. I've played in several bands over the past 12 years and used many different and some high end amps. I bought the Acoustic A20 for home practice and small gigs. The 20 amps will surprise you. It is plenty loud and has great effects. I would recommend this amp to my friends

        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.
