Nux Mighty Plug Pro

I've had a couple of hyper-portable multifx units before (Korg Pandora MINI, Mooer Prime P1) and there is always a constant problem of quality. I don't mind excessively to this as I use these kind of machines mostly for exercising, when bringing guitar on holidays, for pre-stage warmup etc., but honestly, this time I was quite blown away by this machine.
1. the sound quality is absolutely good. Nux proves again able to write usable modelers
2. you can load custom IR
3. the machine is smaller than a credit card
4. it has bluetooth
5. with an unofficial app ("Mightier Amp") you can configure BT midi controllers like MVave Chocolate to operate it remotely
6. it can play backing tracks
7. you can even prepare cue points on the backing tracks to change preset

The only drawback is that the output is a minijack, so in case you want to go to an external PA you need an adapter from 3,5mm to 6.,3mm stereo jaack

I purchased this small headphone amp to use my electric guitar and bass more. Nowadays I almost always reach for the classical guitar, but sometimes I cannot play on loud instruments (night, weekend, wife taking a nap etc.)
This gadget is great for allowing me more practice time, the sounds are nice and endlessly tweakable and the app is well built. I have two issues with it: the plastic feels very cheap (but durable) and the swivel joint of the jack plug feels not durable (and not solid).
All in all I would recommend, I feel it can do more than the advertised 5 hrs and it makes me practice/play more. It also works with my electric bass guitar!
