Still rocking at 68
I looked at multiple different amplifier options and this one always came out on top. The reviews were always positive for sound and quality. With that being said, I'm very happy I chose this product!

Great Bargain
For the low price you get reverb and chorus effects. multiple inputs. But the only complaint I have is there is no headphone output.

Great Value
It looks and sounds really good. The amp and PA put out clear nice clean tones. For the price I wasn't really expecting too much, but it did not disappoint. Shipped right away.

Excellent Amplifier at a Great Price
This is a great amp for a great price. I use it along with my Stage Right 30 watt tube amp to play along with loops. I use this amp primarily in my home studio, so my comments are specific that that type of use. The tone for the acoustic guitar is excellent and the onboard equalizer and effects do a great job. Hard to believe there is so much amp for such a great price. I would recommend this amp to every guitar player in the world.

Pleasantly Surprised
Everything works as expected. It has a really good sound and decent volume too. Appears to be well made. My only negative is that there is no way to apply any effects to the MIC input, but I kind of knew that going in. Well worth the price I paid.

Great amp
This is a very good amp. Good fit and finish, responsive, controls, and good sound. The RCA inputs are a great addition. I am using these to run a Bluetooth receiver. Play music from my phone. This is a great option to jam along.

Just getting to know it. Very impressed...meets or exceeds expectations...surprised pleasantly with the "active/passive" pick-up switch...can swap to electrics and add in mild but satisfying reverb/chorus effects. Looking forward to "All" the features. Thanks, great versital + bedroom amp.

Really love my monoprice 20watt acoustic amp as it sounds great with my acoustic guitars. Also love to loop whatever I?m playing on my acoustic guitar on it and improvise over it with my electric guitar using my monoprice 15 watt tube electric guitar amplifier with spring reverb. They not only look good together but also sound great together. Also Use their effect pedals and patch cables because they are good quality and sound great also. You will not find a better price anywhere on the internet. This is good quality stuff. Thanks to monoprice for making things affordable.

There?s only one drawback that is that the microphone channel has no EQ

Excellent Sounding Little Amp
This amp sounds great for it's size.Excellent practice amp and loud enough for a small room. Perfect for house concerts. The reverb could be a little more "reverby" , but it's not bad. The chorus modulation is adequate, and provides a nice "shimmery" sound. Can't beat it for the price.

Love it
I love it. Mainly use it in my room when song writing at night. Also run a delay pedal and sounds great!! The line out jack is also a plus instead of beating up your little 8" speaker (which does okay. but it's only 8" so what do ppl expect?).. The price has gone up $10 since January. But hey "let's go Brandon".. ?? Thanx again monoprice...

Decent little amp for the price
Nice home practice amp, good value for the price. Could be louder, and cleaner at loud volumes. Won't work for anyhting except home jams or small coffee shop gigs, but works fine for what it is

Seems nice for the low cost.
I actually have not used the amp yet. I hooked it up to test and make sure it works.But I haven't had any opportunity to use it to perform and put it to the real test.

NICE!
Best $80 bucks I ever spent on musical equipment. The chorus has a throb to it if turned up to high, however if you combine the chorus with the reverb both set @ 4 magic!

A powerful small amp, with great tone, easily recommend it to anyone wanting an acoustic/pa amp.

Most bang for the buck
This is a nifty little practice amp that includes reverb and chorus for an incredible price. Compare the Vox Pathfinder 10 which has one channel, no reverb or chorus and two-band tone controls at around the same price. This beats all the other 10 watt amps.

Just OK for $100 amp
For the price it does just Ok. Nothing fantastic. It does not compare to my Brugera and certainly not my ER acoustic amps but they were 3 and 7 times the price.
