Nux Mighty Bass 50BT

An astonishing amount of clever processing goes into persuading a single 6.5” driver to produce such volume and depth from this lightweight package. But if it’s important to be able to play along to backing tracks, you need to be aware that none of that clever processing is applied to the aux-input, which consequently sounds really strangled. More important, I didn’t find it easy to achieve a clean ‘acoustic’ sound from my electric upright bass. You will say I should have bought something less sophisticated without smart-arse modelling and a phone app. Indeed. And that’s what I’m going to do.

Great little bass practise amp especially for solo practice at home with the potential to annoy your neighbours. Initially I was a little disappointed with the unit having less practise drums than its little cousin I had been previously using (the mighty plug pro) and hoped that would be rectified with a firmware update only to find out there hasn’t been any since 2021. However the unit does function perfectly the effects and virtual pedals are bass instrument specific and can produce some crazy sounds. I soon got over the missing practice drums and was able to record some drum jam tracks to play through the app instead. I’m a uk customer and it first came supplied with a euro two pin plugged kettle lead for the power supply, Thomann costumer service responded to my email the same day and dispatched a 3 pin uk alternative instantly 👍. The amplifier comes with a shed load of features, has decent build and sound quality, is loud for such a small size. The accompanying mighty amp app is itself updated regularly, very comprehensive, and easy to use. The app can be downloaded and explored before purchasing the unit. In summary it’s a great little amp which is versatile compact and really handy, a little on the heavy side for carting around but it’s grown on me, used daily at home, it’s a keeper!

Is it good or bad? It's good. Quite amazing actually.
It’s quite overwhelming with all the options and features, because the manual is basically pictograms and the online retailers just list 22 bullet points. I found about 6 websites with various info, but no-one actually tells you HOW to work it.
I'm confused with parts of it and I wish someone somewhere explained it. If you already are familiar with modern studio/recording switches and terminology, you will probably work it out.
After playing with everything for 5 days I worked some things out. Top tip: If you wish to use PC/Windows, you download two clucky files: Driver.exe and NuX mighty bass.exe, connect with an old out-of-date USB, configure it, then try to make it actually work without losing connection and needing constant restarts. Then I tried my nice Android tablet with bluetooth. You download the Mighty Amp app from the official Google store, and it starts to work smoothly. It is more obvious how to save settings to three channels. More importantly - it has a 'Reset' function, so you can attempt the three channels and just keep hitting reset until you get it right.
From what I can make out, as a stand-alone amp, the three channels can be activated to have on-board simple effects: simple compressions, phasers through to scream/muff distortion via Para 1 and Para 2 knobs. Then when you connect the app via Bluetooth however, a whole world of IR bundles, amps, and effects open up to you to try out or save to each of the three channels. I think you can even add your own.
The pedal to access and the loop/drum beats functions are very useful, but I just stored them away and use it as a basic amp and it’s good at that.
I am downsizing, so for a small house it is a beast of an amplifier. It sounds great for its size, and does its job very well. I am very happy with it.
