NUX B-8 Wireless Guitar System Review – After Using It Live

The NUX B-8 promises a professional wireless guitar system with a few features that make it more than just a basic wireless.

You get automatic pairing, a smart transmitter charging system, and a receiver that can also work as a tuner or a boost. On paper, that already sounds interesting.

After using the NUX B-8 live, I can say this: it is one of the most practical wireless systems I have tried in this price range.

Disclaimer: NUX provided me this unit and I got to keep it as compensation for my work. However, whether the content is sponsored or not, the company has no say in the things I mention in the video or this post.

What Is the NUX B-8?

The NUX B-8 set comprises a receiver/tuner/boost, a transmitter that charges The NUX B-8 is a wireless guitar system built around a pedal-style receiver and a separate transmitter.

The receiver does more than just receive the signal. It can also work as a tuner or a boost, depending on how you set it up. On the sides, you get inputs, outputs, and an effects loop. On the back, you get power, ground/lift, XLR out, and USB-C for updates. The unit even lets you upload your own startup image, which is admittedly a bit silly, but also kind of fun.

Another clever feature is the charging system. You can charge the transmitter by placing it on top of the receiver. If you want to keep the screen visible, you can also charge it through USB-C on the back.

According to NUX, the B-8 works with electric guitar, bass, acoustic guitar, ukulele, and keyboards.

The NUX B-8 Transmitter

The transmitter is one of the more unusual parts of the NUX B-8.

Unlike the metal receiver, the transmitter uses a plastic housing. Normally that might worry me a bit. However, the upside is that it is very light. At 63 grams, it is easy to attach to your strap, and once everything is in place, you barely notice it while playing.

The transmitter connects to the instrument with the included cable. In use, I found the whole system comfortable and easy to forget about, which is exactly what you want from live gear.

There is also a long cable simulation switch for players who want a slightly different feel, plus a mute button on the transmitter itself. I found that mute button especially useful during longer breaks, because it let me unplug my active bass and save battery on the bass itself.

Wireless Connection and Everyday Use

• Getting the NUX B-8 up and running is quick.
• Powering the unit on and connecting to the transmitter takes only a few seconds. After that, the screen gives you genuinely useful information. You can see both the wireless signal strength and the remaining battery level of the transmitter. For live use, that is a very welcome feature.
• The controls also feel solid. The buttons and selector knob give the impression that this is meant for serious hobbyists and semi-professional players, which makes sense at this price point.
• Inside the menu, there are also a few useful settings:
• Two different home screen options
• Adjustable screen brightness
• Custom startup image upload
• Language settings
• TX/RX setting to balance latency and signal stability
• Three tuner display options
• Bypass mode options for tuning
• Footswitch assignment for tuner or boost
• Boost level adjustment up to 12 dB

That all makes the NUX B-8 feel more thought-out than a lot of basic wireless systems.

Using the NUX B-8 Live

This is where the NUX B-8 made the most sense to me.

In live use, the wireless connection was great. Pairing was quick, and while walking around the church with my bass, I had no dropouts or other issues. That alone already made a good impression.

What I liked even more was not having to guess what was happening. I could see both the signal strength and the battery level on the screen. That makes the whole live experience feel a lot less stressful.

The tuner was also fast and accurate. It worked well enough that I could tune even between songs. On top of that, the transmitter stayed comfortable the whole time. Because it is so light, I quickly forgot it was even there.

IS THE NUX B-8 Good?

Yes, I think the NUX B-8 is very good.

It works well, it is easy to use, and it includes several clever features that make it more practical than a standard wireless unit. The tuner is good, the boost is useful, and the screen gives you the kind of information you actually want to see during a live set.

That said, I do still have a few questions.

First, if the transmitter breaks, how easy is it to get a replacement? The manual suggests you can pair different transmitters with the main unit, so clearly NUX has thought about that. Still, it is something I would want to know for long-term use.

Second, I have the same question about the cable between the transmitter and the instrument. If that cable breaks, how easy is it to replace?

Third, I was not immediately sure what I would personally do with the effects loop. The most obvious use case to me was muting a larger part of the rig. However, a helpful YouTube comment pointed out that the FX loop becomes much more useful if you want to run effects in the chain and also use the DI output.

Final thoughts

The NUX B-8 is a smart and practical wireless system that feels designed by people who understand live use.

It pairs quickly, works reliably, and gives you helpful real-time information on the screen. More importantly, it made playing live feel easier and less stressful, which is exactly what gear like this should do.

If you want an easy-to-use wireless solution that goes beyond the basics without getting ridiculously expensive, the NUX B-8 is definitely worth considering.
