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!

The amp impedance is too high if you plan on using low impedance high sensitivity IEMs, like the KZs. It gets fixed with an impedance “adapter”, the 30 ohms ones from aliexpress work great. If you don’t you will hear a weird hiss that will drive you nuts.

It has a 5h battery life more or less, around 3 with the impedance thingies. It works. It doesn’t charge super fast. It charges at 5w, higher quality charging batteries/controllers are a few cents more, heck, phones this price do.

Really good modeling with tons of effects, really good actually, it really surprised me. The bass sounds are quite good, the guitar sounds seem quite good too, I have not spent a lot of time with those.

The octaver is buggy wtf, the tracking is very fast but it is a semitone off half the time, so I can’t practice the synth octaver parts on this, which is a big bummer.

I just wich you could record the sound off of bluetooth, using the cable is kinda jankie, it works, but bluetooth would be amazing and every instagram player would use it lol.

So good enough for practice.

Eigentlich wollte ich den Katana Go, der war aber nicht verfügbar also ist es dieser Kopfhöhrerverstärker geworden. Leider habe ich keinen Vergleich, bin aber zufrieden. Viele Effekte, die App ist ok wenn auch nicht besonders übersichtlich. Was anscheinend nicht wirklich funktioniert: das Gitarrensignal via USB C ans IPhone zu leiten - zB Verwendung als Audio Interface für die Gibson App um amplification / effekte zu nutzen. Im Kopfhöhrer höre ich den Gitarrensound vom MPlug und (wenn das patchlevel richtig eingestellt ist, default ist zu niedrig) die Begleitung aus der App, jedoch keinen von der App modifizierten Gitarrensound.

The device has everything I need for practicing bass with headphones: a huge range of effects and rhythm options. It also acts as a sound card for the computer, allowing both playback and recording. I like that it has a built-in battery that charges when I connect the device to the computer via a USB-C cable. In addition, the device can be connected to a phone or iPad via Bluetooth. Various effects can be set in the application, which can then be easily changed on the device (even without a connected computer or phone). The only thing that bothers me is a bit of noise or artifact, which appears even when I play without all the effects. Otherwise, it's not a problem for playing, but it would be annoying if I wanted to record music for more serious purposes.
