MOOER GWU4 Wireless System Green Instruments Wireless Set
This guitar wireless system has proven to be a Great addition to my little studio and my MOOER travel rig with the Mooer Prime P1 multi-effects processor and MOOER GTRS PRNR GCA5 Mini Bluetooth Amplifier. My travel rig pictured with an Epiphone Les Paul Standard Plus top.
I’ve tried a handful of inexpensive wireless guitar systems with generally good results. But every system had something that was sub-optimal. So far, this Mooer GWU4 has performed flawlessly and outperformed all of the other systems I’ve tried.

What I like about the GWU4
- In A/B testing against a new guitar cable I could not tell any difference in sound quality, hiss, etc.
- I was able to walk all throughout my 3 story house while playing and never lost signal. I definitely can’t go past the 2nd floor with my other wireless systems. I suspect that the little wire antennas hanging out of the transmitter and receiver get some credit for extending the range of this wireless system.
- The transmitter and receiver appear to be built a bit thicker than my other wireless, which gives me hope that they are structurally more sound and durable.
- The indicator lights are bright enough, but not blindingly bright.
- There are little rubber pads on the body of each unit so that they don’t scratch the guitar or amp that they are plugged into.
- There is plenty of range of motion to pivot the 1/4″ plug for whatever type of guitar you use. It even fits in my EART headless with a recessed jack that does NOT work with some of my other wireless and mini headphone amps.
- I love that it comes with a Y splitter charging cable so that I can charge both units while only taking up one USB port.

What I don’t like about the GWU4
- The color. Black wasn’t available when I was offered this for review… which is a shame as it would have matched my MOOER GTRS PRNR GCA5 Mini Bluetooth Amplifier. The pastel seafoam looks fine, I guess. But doesn’t fit with any of my gear.
