Line 6 Relay G10S Guitar Wireless System with G10TII Transmitter

Line 6's wireless rig is better than ever -- with the G10TII plug-on transmitter for up to 7 hours of playing time, and a receiver made for your pedalboard.

The Relay G10S instrument wireless system is as powerful as it is compact. The stompbox-sized receiver offers professional features, rugged build quality, and plug-and-play operation at an easily affordable price. The Relay G10S system integrates seamlessly into any pedalboard or can function as a standalone unit. It features an impressive range of up to 130' line-of-sight, enabling you to move about untethered on any sized stage-and the Relay G10S works equally well with active or passive pickup systems.

The Relay G10S is a member of the Relay Wireless Family, a series of products that are embraced by professionals for their reliability, ease of use, and transparent sound. Thanks to the extensive experience that Line 6 brings to designing and manufacturing wireless products, you can depend on the Relay G10S to provide clear and accurate instrument sound, free from interference. Plus, the Relay G10S is compatible with the Relay G10, G30, G50, G55, and G90 guitar wireless systems


Getting up and running with the Relay G10S is simply a matter of powering it on-no complicated setup required. When powered up, the unit immediately locates and locks onto the strongest available wireless frequency, and you're ready to rock. You can also adjust the frequency selection manually, although you'll probably never need to.


Some wireless products in this price range are housed in plastic, making them less-than-optimal for stage use. Not the Relay G10S, read more which features a rugged metal housing designed to withstand the rigors of gigging. And RF and battery status indicators are conveniently located on the face of the pedal, making it easy to monitor system status at a glance.


Relay G10S offers pristine, 24-bit lossless digital audio quality. It features an extraordinary 10Hz-20kHz frequency response, so you'll hear the entire spectrum of your sound, even when playing instruments with extended ranges.


The Relay G10S pedal has a convenient 9V DC power input. You can either use the included power adapter cable or connect it to a plug from your pedalboard's power supply. The G10TII transmitter runs on a rechargeable battery that lasts for up to seven hours. What's more, the battery automatically enters sleep mode when you're not playing, significantly extending how much playing time you can get from a single charge. When you're ready to recharge, just plug the G10TII into the Relay G10S receiver and it automatically begins recharging.


Relay G10S is equipped with two different outputs, making it extremely versatile. In addition to a standard 1/4" jack for connecting it to your pedalboard or amp, there's also a balanced XLR output that allows the G10S to be used as a wireless DI box for applications such as connecting acoustic guitars or basses directly to a P.A.

"Line 6 Relay G10S review"

Overall: 3.5 out of 5 stars
(see rating details)
Verified Customer zZounds has verified that this reviewer made a purchase from us.
I purchased this unit as a quick and affordable option. At first, it was great. Very responsive, signal strength was good, didn't effect the natural tone of my guitar as much. After about 3-4 months of steady use at gigs and practices, i've noticed that placement and weather are a huge factor to the functionality of this unit. My bandmates all have their own wireless units as well but a different brand and often times I find myself adjusting the placement of my receiver because it's either too close or too far from their Shure receivers. (Note: their units have never lost signal strength, only my Line 6 unit) Also, I've noticed that on windy gigs my signal is constantly cutting off to the point where it sounds like Im using a tremolo effect on my guitar, and again my bandmates' Shure wireless units still function properly no matter how windy it may be. Not sure if anyone else has experienced this or if I just got a defective unit. Either way it's still a decent unit to use for practice or small gigs. I plan on keeping this unit for practices and purchasing a Shure wireless system pretty soon for gigs. Unfortunately, like many other things, you get what you pay for so keep that in mind!
