Wireless freedom

Despite their incredible potential, wireless systems have in the past often failed to deliver on their promise of a cable-free future. Various technical issues such as intermittent drop-outs, hum interference, and high latency have sadly deterred musicians from embracing this technology. Thankfully, huge strides have since been made to address these problems, with even professional musicians no longer able to notice whether a guitar or bass is connected wirelessly to an amplifier. With the GTRS GWU4 Wireless Plug, shown here in its green incarnation, Mooer has achieved this feat thanks to ultra-high frequency technology that guarantees a latency response of less than 3ms in addition to a frequency response of 20Hz to 20kHz and a dynamic range of 103dB, and the whole solution comes at a very attractive price.

Plug in and play!

The GTRS GWU4 system is a set that comprises two dongles with 6.35mm (1/4") jack connectors that serve as the transmitter and receiver. Both of these house an 800mAh battery for up to six hours of performance, which should be more than enough for even the longest live gigs! The included Y-style USB-A to USB-C cable can charge both dongles simultaneously in 2.5 hours, and an integrated LED indicator helps keep track of the battery life. Thanks to the GWU4's channel selection feature, it can work with up to four GWU4 receivers for use with different amplifiers or multi-effects units. The colour of the LED indicator also denotes the currently selected channel. As long as there is a clean line of sight between the transmitter and receiver unit, the wireless system offers a range of up to 30 metres for freedom of movement on stage and in front of the audience.

...and wireless for all

Compared to early wireless systems, which were an expensive niche reserved mainly for professionals, today's systems are not only technically more sophisticated but also much cheaper, more compact, and less susceptible to interference. With its low latency and outstanding sound quality, the Mooer GTRS GWU4 Wireless Plug Green is an excellent choice for those on a budget looking to experience the freedom of connecting their guitar or bass wirelessly to an amp without the compromises that had to be expected in the past.

About Mooer

Mooer is based in the Chinese city of Shenzhen and has been making products for guitarists since 2010, which include compact single pedals through to multi-effects units and compact amplifiers. The company initially produced a range of mini pedals before making perhaps its most significant breakthrough in 2016 with the sophisticated Ocean Machine delay pedal, which was designed in collaboration with Devin Townsend. Mooer's product range now also includes solutions that feature amp modelling, IR-based speaker simulation, and matching equalisers, and the company's focus remains firmly on the use of digital technology.

From wireless convenience to freedom on stage

Time to say goodbye to tangled and accidentally unplugged cables, and say hello to a world of freedom and peace of mind both on stage and at home. The Mooer GTRS GWU4 Wireless Plug's range of up to 30 metres allows users to unleash their inner rockstar during performances, and the ability to wirelessly operate one transmitter with four GWU4 receivers opens up numerous options for addressing different amps, modellers, or multi-effects units simultaneously. Not having to worry about cable runs also means that musicians can even head over to the kitchen and grab a coffee or tea without having to put their instrument down when they are jamming at home.

Really Good System
howardjworf@aol.com 05.02.2023
I'll update this review in a few week's time when I have used them for longer. I have an AKG wireless system, one with a receiver box that sits on the amp, but I wanted a more portable system for rehearsals. These are superb IMO. I've used them with active basses and passive guitars. They feel really well made, are very easy to use, and although I cannot yet speak for the battery life I have used them for 3 hour rehearsals and occasional use in between before recharging. Later - I have now established that the battery life for me exceeds 6 hours. More than enough. I plug the receiver unit into the input of my multi effects pedal and then cable to the amplifier. So even though the receiver is on the floor I haven't had any dropouts. The sound is to my ears indistinguishable from using a cable. The fact that the unit has an external aerial and that it can be angled as desired probably helps a lot. I'm thinking of buying another set.

I am very pleased
ilia_d 19.10.2024
All the low-budget ones looked very similar, but these ones stood out - they had a frequency different from 2.4 kHz, which means they won't conflict with Wi-Fi, and they also use a Type-C connector for charging, which is much more modern than the micro-USB (or even mini-USB) of most others.
I use them with a bass guitar at rehearsals and concerts for 9 month.

Pros:
- The sound quality is very decent. I'm not sure I can tell the difference even with headphones, let alone concerts. No interference from other devices.
- The battery life surprises me - I haven't measured it, but it feels like it's about 5 hours. Most often, it's enough for 2 rehearsals of 2 hours, but they usually run out on the third one. And the unit that's plugged into the guitar always runs out first. I also haven't measured how long it takes to charge, I think it's about 1 hour.
- It has an interesting function when you can use 1 transmitter for several receivers - for example, output sound to several amplifiers without unnecessary switching, or record sound to an audio card in parallel with the sound output. I did not use this, but it is better to have such a function than not to have it. Most other transmitters do not have this.

Cons:
- Color. The color itself is beautiful, but I would prefer to use black blocks, which are available in China, but here you can only buy white and green.
- The bending point is quite mobile, so when connecting from the side, it will go down and this does not look very aesthetic. Fortunately, I came up with the idea of ​​hooking the wire to the bridge of my headless bass - it is convenient. Otherwise, I do not know what I would do.
- The connection can be lost for a couple of seconds, but this happens rarely, literally once every few hours. It is not critical, since this is a fairly cheap device, and not a professional one, so I cannot demand much from it.

As I wrote in the title - I am very pleased with this device. I don't see any alternatives to it even for twice the price. If I were to change it, it would only be for a black version of the device.

Hiss and tone suck
Conan D 18.05.2023
Sadly, I found there was considerable hiss and the sound was like someone had thrown a towel over my amp, compared to a physical lead. I sent them back.
