    • Outstanding performance in a compact package for my acoustic jazz guitar.
Purchased primarily for home practice. I bought this acoustic guitar amplifier for playing jazz. My guitar is a custom Godin Fifth Avenue acoustic archtop with a Benedetto S-6 floating pickup and Thomastik-Infeld flat wound strings. The performance of this little amp is nothing short of amazing. I am playing in a neutral EQ position with lots of room to customize. The amp delivers clean, crisp, tone. By preference, I do not have volume and tone pots on my guitar and dd not need them with this amp. The reverb and chorus effects are excellent, and the amp has plenty of volume for my purposes (small to medium quiet room). Other pluses are the portability and battery feature, and the very modest price. The amp appears to be very well made with simple and thoughtfully laid out controls and very attractive appearance. I keep it in a soft padded camera case for safe storage and travel. I have not tried the Bluetooth function and don't anticipate that I will use it. All-in-all meets and exceeds my every expectation. ... show more

    • Small but mighty
When I opened the box and saw this cute little amp I thought what did I buy? So after charging it up I plugged into my acoustic guitar and wow was I impressed. It has just enough power to give you a good sound and the effects are cool feature. If you want a good little amp for practicing that won’t disturb the neighbors this a good choice and value. Bluetooth is a cool feature as well and not having to plug into the outlet makes it easy to move around wherever I need it. I’m pleased with this little amp so far ... show more

    • Decent Little Unit
Appearance was a bit disappointing. The fancy wood looking wrap was not put on well so I have wrinkles in my wood... Aside from that it's a pretty cool little unit. Sound is really nice. Blows me away actually how good it is. Loud enough to fill my backyard! The effects work well. Seems to be built solid. Is a bit heavy and awkward so a strap would be nice. Decent little amp for this price though... ... show more

    • REPLACEMENT Batteries Update
Review Image by Some guy
Review Image by Some guy
Amp was excellent HOWEVER the replacement rechargeable battery pack is EXTREMELY difficult to find. Access and removal are simple BUT ALL AVAILABLE REPLACEMENTS ON AMAZON HAVE THE POLARITY REVERSED and no information about where to order the correct plug version is available at this point (02/02/26) ***** NOTE: If you’re amp has the access panel on the bottom AND you can see the small red plug in the middle of the wire… you can (currently) get a replacement on Amazon that you can easily reverse the red and black lines as or if need be. Look up JST connector and find the same type. There is currently a short YouTube video on how to disconnect the tiny connector leads that you simply reverse the wires and gently bend the tabs back into position and slide and click back in. UPDATE: ordered replacement battery with same connector type visible. When the battery arrived I gently depressed the tiny clip visible in each little square of the plug with the tiniest eye glass screwdriver that I could find, and pulled on each wire out separately, reversed them, and plugged them back in. Working perfectly. Next time I will probably try to get the batteries individually and reuse the old connector to bundle them if possible. Might be cheaper at a batteries plu store (?) ... show more

    • exceptional quality sound for acoustics with high quality pickups! Seems well made as well!
Absolutely incredible little box!! I usually play my acoustic Gibson and Taylor guitars thru a $1200 Acus acoustic guitar amp....though not as powerful ,the sound of this tiny box is challengingly close to the same sound! I'm blown away. The reverb and chorus, delay effects are exceptional, the fact that its battery powered, blue tooth compatible and light weight as well as crazy small is just a great surprise! It charges fast, and if pointed to a smooth wall and placed about a foot away , it will use that wall as a sounding board for an even greater surprise as it sounds half again louder that way. It's just Great1 ... show more

    • What a nice compact acoustic amp!
I’d forgotten how pretty my Martin sounds with just a touch of reverb and chorus. If I were playing out somewhere with a band, I would definitely take this amp and mic it through the PA. It sounds beautiful.

    • Will not charge or play
It pains me to write this review because this little amp sounds great and looks great. But it charged a grand total of one time, and then the USB C port went dead and it will not charge or play again. It is now a paper weight.

    • Decent for what it is
Looks good. Sound quality is good for a very small amp. Reverb and chorus have good sound quality. Blue tooth works good. Rechargeable internal battery is nice for where you don't have a source of electricity. It is not loud. You can turn it up all the way and it's loud enough for small/medium size rooms, or to give your acoustic guitar a nice boost, but don't expect it to bust your ears. Also, it doesn't have a strap, which to me isn't a deal breaker. But for some it might be. It's not a rugged toss around build type like most amps, but more like a small piece of furniture! I bought it to give my daughter for her birthday. It should be good for what she will use it for. The price was also right. ... show more
