The Most Complete Practice Amp On The Market? – NUX Mighty Space Review

SNUX has been making some really interesting practice amps for a while now, and the Mighty Space feels like the most complete version of that idea so far. It has wireless guitar connectivity, a rechargeable battery, stereo speakers, USB recording, app control, jam tracks, a drum machine, a looper, an included footswitch, and even a speaker out.

So yes, on paper, this thing does a lot.

But as always, the more important question is not whether the feature list looks good. The question is whether the amp is actually fun to play, easy to use, and good enough to justify its place in your practice setup. In this NUX Mighty Space review, I’ll go through the features, first impressions, sounds, app control, and the things I liked and didn’t like after spending time with the amp.

Disclaimer: NUX provided me this product, and I got to keep it as compensation for my work. However, NUX has no say in the things I mention in the video or this post.

NUX Mighty Space Features

The NUX Mighty Space is basically built to be the center of your practice rig. It is not just a small modeling amp with a few presets. It is trying to be the amp, effects unit, jam tool, looper, recording interface, and wireless practice setup in one box.

Some of the main features include 30 watts of power, NUX’s TSAC-HD amp modeling, 512-sample IR resolution, 34 built-in impulse responses, 20 user IR slots, seven presets with active functions, and effect blocks for gate, compression, effects, amp, IR, EQ, modulation, delay, and reverb. The order of those blocks can also be changed, which is always nice.

It also includes drum and loop functions, the NMP-2 Lite footswitch, a rechargeable battery with up to seven hours of playing time, 1.2 ms system latency, and support for both the MightyAmp mobile app and Mighty Editor desktop software.

That is quite a lot for a practice amp. Maybe too much, depending on what you want from one.

NUX Mighty Space Specifications

The Mighty Space runs at a 48 kHz / 32-bit sampling rate and has a reported system latency of 1.2 ms. The built-in battery is 11.1V / 5000mAh, and the amp measures 363 x 171 x 171 mm. It weighs 4.06 kg, so while it is still very portable, it is not quite the tiny grab-and-go thing some of the smaller Mighty amps are.

That extra size and weight does make sense, though. This amp is clearly meant to sound and feel bigger than the smaller models in the Mighty range.

First Impressions

Unboxing the Mighty Space was genuinely fun. NUX packs their amps well, and in this case everything from the power supply to the footswitch is included. That already makes the amp feel like a complete package rather than something where you immediately need to buy accessories to use all the features.

I have had most of the NUX amps in my studio at this point, and the Mighty Space is easily the heaviest one from the range. I was hoping that also meant it would have the biggest sound.

The amp itself feels solid and well-built. The carrying handle feels sturdy, which is important because this is still very much a portable amp. It is not exactly heavy, but it has enough weight to feel like a proper piece of gear rather than a toy.

The wireless dongle is a different story. It works, and I like that it is very light, but it does feel a bit plasticky. That is not the end of the world, because the low weight is actually a practical advantage when it is plugged into your guitar. I also really like the fact that you can charge it by plugging it into the guitar input on the amp. That is a simple idea, but a good one.

I was already familiar with the NUX phone app and desktop editor, and I have generally liked both of them. So the main thing I wanted to know was whether the Mighty Space actually sounds different from the smaller NUX amps.

How Does The NUX Mighty Space Sound?

This is where the NUX Mighty Space review gets more interesting.

I grabbed my Sterling JP-150, plugged in the wireless transmitter, and was playing within seconds. That is one of the strengths of this amp. It removes a lot of the small annoying steps between wanting to play and actually playing.

In my experience, the average preset on NUX products ranges from good to very good, and the Mighty Space did not disappoint here either. If you have used almost any kind of modeler before, the sounds and workflow will feel familiar very quickly.

The AC30-style sounds do what you expect them to do. The Plexi-style sounds are also in the right ballpark. In general, I have always found NUX amp simulations to be good, especially considering the price range and the kind of products they usually appear in.

The bigger housing and stereo speakers also help. There is more of an “amp in the room” feeling than you get from some smaller practice amps. It also gets loud enough to annoy your neighbors, which may or may not be a useful feature depending on your living situation.

The amp sounds bigger than its smaller siblings, and that is probably the biggest sonic difference. It does not magically become a full-sized tube amp in the room, but it does feel more substantial than many small practice amps.

Desktop Editor vs. Mobile App

The desktop editor and mobile app both make sense, but they feel slightly different in use.

The NUX desktop editor is more focused on building and shaping tones. It is where I would go for deeper editing, uploading custom impulse responses, arranging effect blocks, and doing more detailed preset work. If you want to create your own sounds properly, this is probably the better tool.

The mobile app feels more like the practice companion. It is useful for playing, changing sounds quickly, using jam tracks, and getting ideas going without sitting in front of a computer.

Most of the features are available in both places, but the mindset is different. Desktop is for editing. Mobile is for playing. That is probably how it should be.

What I Like About the NUX Mighty Space

Overall, I think the Mighty Space is a very strong addition to the Mighty amp range. It sounds bigger than the smaller models, it feels more complete, and it has enough features to genuinely become the center of a home practice setup.

The amp modeling is good, the effects are useful, and the extra tools make a big difference. Jam tracks, drum tracks, the looper, wireless playing, battery power, and app control all add up to something that feels very practical.

I also really like that the footswitch is included. With an amp like this, the looper and drum machine are much more useful when you can control them without touching the amp or app constantly.

The whole package feels like NUX actually thought about how people practice. Not just how they dial in tones, but how they sit down, grab a guitar, and start playing.

What Could Be Improved?

Even though the Mighty Space sounds bigger than the smaller NUX amps, I would not say it sounds huge.

It gets loud, and it has more body than the smaller models, but the tone is still quite guitar-focused. That works well when you are playing guitar through it, obviously. But if you want to use it as a general Bluetooth speaker for listening to music, it can feel a bit underwhelming.

That mid-focused character makes sense for guitar, but it does not necessarily make full mixes sound massive.

The wireless dongle could also feel a bit more premium. Again, it works, and the light weight is nice, but the amp itself feels more solid than the transmitter.

Is the NUX Mighty Space Worth It?

If you are looking for a compact practice amp that can do almost everything, the NUX Mighty Space makes a very strong case for itself.

It is not just a modeling amp. It is a wireless practice rig, an effects unit, a looper, a drum machine, a jam tool, a recording device, and a portable amp in one package. That is a lot of functionality for one box.

I think it makes the most sense for guitarists who want a fun and flexible home practice setup without building a full pedalboard, interface, monitor, and software-based rig around it. You can just turn it on and play, which is honestly one of the most valuable things a practice amp can offer.

Final Thoughts on This NUX Mighty Space Review

The NUX Mighty Space is probably one of the most complete practice amps I have tried.

It sounds good, feels solid, includes a lot of genuinely useful features, and makes practicing easy and fun. The wireless system, built-in battery, footswitch, looper, drum machine, app control, and USB recording all add to the sense that this is not just another small modeling amp.

It is not perfect. I would not use it as my main music playback speaker, and the wireless dongle does not feel quite as premium as the amp itself. But as a guitar practice tool, it is a very solid choice.

If you want a practice amp that looks good, sounds good, and gives you almost every practice tool you could realistically need, the NUX Mighty Space is definitely worth checking out.
