Nux Mighty Lite BT MKII

My goal was to use it mainly with the Rocksmith or Yousician connected with the USB cable with my laptop as a portable setup.
Second use case would be to have it drive my headphones during practice session.
Third would be to pack it and visit my friends to jam together.

I think it would be good for the part of the second and third use cases.
Unfortunately I cannot use it without the plugged in power supply with the USB connected at the same time.
It does not matter if I try to power it with my laptop via USB-C or have batteries inserted when the USB is plugged in there is a significant noise coming from the speaker/headphones connected to the amp. The only way to get rid of that is either disconnecting the USB (no audio interface anymore) or connecting the power supply with the barrel plug (byebye pure battery powered portability).

Apart from that it is very nice and definitely sufficient for the practice amp.
Is it small enough that you can feel that you can put it in your bag pack and just go? Yes.
Is it plasticky? Yes, but it is quite sturdy.
Would I buy it again? Nope. I need a small amp that can be used with the PC without the AC adapter connected. This one does not check that mark.

I own a tube amp head and practice using vst amp sims. But this little thing made me really happy. It's not a toy, it's a great practice/noodling amp. Many many features, especially when using its android/ios application. Much louder than expected but loudness is not its purpose. Sounds really good. Nice materials and quality. I would buy it again.
Only downside that you can't change effects queue. I am pretty sure nux will fix it at a later update

I'm still amazed by this tiny beast!
Not only it's loud (considering its size), but the quality of its simulations has left me speechless ever since I bought it.

I'm a huge fan of tube amps, so much so that I bought tube amps of any size back in the day. 5w, 20w, 50w, 100w... I had them all! I also had some pods but they never satisfied my ears.
I sold my tube amps because I had to move to the UK, and I've been looking for a new amp to buy to start practicing again, and possibly get back in the game. But I needed something practical, and I was a bit skeptical about the most recent digital pedalboards. Then I got to know about this beast, and I had to change my mind once and for all.

Believe me, it's no toy and the sound quality is awesome - it might fry a little past 3 on the volume knob, but that's cause the speaker is meant for quick, practical desk use. Once plugged in your headphones, you can crank that volume up and it just sounds amazing.
You can control it with a very straightforward app that connects to the amp via Bluetooth. The amp comes with 7 presets that will blow your socks off, but the potential expands once connected through the app as you can play with many simulations and go for the sound you like.

It changed my mind and I'm seriously thinking of taking it up a notch and going for a Trident, as the simulations should be the same (if not better, on Trident).

A must-have.
