Compact Excellence: A Micro Amp that Surpasses Expectations
Alienproject 02.02.2024
In the realm of ultra-portable guitar amps, this product stands out as a testament to exceptional design and functionality. Despite its compact size, the sound quality is remarkably good, providing a satisfying experience for practicing sessions. The accompanying app is a highlight, boasting a well-thought-out design that enhances the overall user experience.

One particularly impressive feature is the amp's volume, which proves to be more than adequate for effective practice sessions. The convenience of the app further extends to the ease with which presets can be searched, simplifying the user's journey to find the perfect sound.

However, a minor inconvenience surfaces in the absence of a feature to sort presets based on their like counts after a search. While this may not be a deal-breaker, it is a noteworthy point for those who value quick and efficient preset navigation.

In conclusion, if you seek a micro amp that defies its size with excellent sound quality, convenient app functionality, and ample volume for practice, this product is a standout choice. The only minor drawback lies in the inability to sort presets by popularity, but overall, it remains a top-tier option for musicians on the go.


Amazing little amp. Great for a practice in a small room.
silencio 10.12.2023
Good quality material, feels sturdy. Very versatile because of its small size, fits into most of guitar cases. battery powered. Connects to a phone/computer with bluetooth. Lots of tones. Very easy and intuitive to use. Ability to plug in the headphones, and to store presets.
Of course, it will not sound like a big, expensive amp. But for a practice in a small room, outdoors its a great choice. Just what i needed. A small companion. I tend to practice at home at the speaking volume anyway, and for that this amp does exactly that. The amp probably is designed for more distorted sounds, but I play mostly clean guitar and its really good. Just have to spend some time dialing in the tone that you want, and there are endless possibilities regarding that.
I use it at mid-to-low volume, meaning - never put it at 100% volume. And its just for practice ant speaking volume. If you need the sound to fill the room, probably look for another alternative, or get a bigger one. This tiny amp is not meant to be tortured.


Surprisingly good
TMOG 19.03.2024
Considering the small size, the sound is surprisingly good. The app is really easy to use and one can quickly find or make just the right sound. I use it a lot with earphones, then the sound is just as good and probably better than my full sized amp.


will work with it on stage 21.03.2024
this is a cool thing, very functional and very good sound quality but it is quiet, personally I connect it to a large mixer and will work with it on stage
