Customer ratings for Alto ÜBER FX

Everything great, what can I say!!!
Anytime again

I had already tested several battery boxes, which were either too big, too small, too heavy or too expensive. I needed a box which I can use as a player for my half-playbacks. Among other things, I'm on the road as a saxophonist and clarinettist and then need an appropriate box for small dinner jobs (the half-playbacks are as MP3 on the tablet, which is connected to the box via Bluetooth). A mic is also connected, as I sing the odd song and to have a reverb effect for the blower. All this makes the Über FX with a very good sound and enough reserve to sound up to 100 people (of course, only with dinner music and not too loud dance music). The trolley telescopic handle is very stable and is also suitable for attaching a tablet holder, on which then rests the tablet. Thus, everything is loosely transportable and I am independent of electricity and space. The battery lasts very long (so far I've played about 15 hours with it and the charge level is still at 75%).
The workmanship is good, the weight fits and the controls are all valuable and easy to use.
The Bluetooth is great and there are no problems with pairing.
I can only recommend this box, because the price is really very reasonable.

Exactly something I was looking for, a medium fully network-independent box with sufficient power for a small garden or birthday party. As described, charging, mobile phone, pad or laptop connect via Bluetooth and off you go.
The sound can be changed when connected via Bluetooth or via Aux in with the sound setting of the external player. In some cases recommended, sounds then simply even better.
The mic/line inputs work well and the tone control is also good. Also the built-in effects.
The price-performance ratio is great, the box is cleanly processed and does exactly what it is intended for.
Battery performance and duration I still have to test.

I was looking for a long time for a battery-powered amplifier to play with the harmonica even times in the pedestrian zone without mains! The Alto-Over meets my expectations almost 100%! The sound is good but you should avoid maximum volume to not overdrive the tones and to save power! The achievable volume is, in my opinion, more than sufficient! Whether the mentioned 50 hours battery power can actually be achieved I have not yet tried. Unfortunately, you can not set any effects but there are separately available devices that can either be connected to the existing USB charging socket or have their own battery supply!
Conclusion: For relatively small money a "great device" that does not need to hide in terms of performance!
