Critic Reviews

Line 6 Relay G50 and Relay G90 Wireless Guitar Systems – MusicPlayers.com

musicplayers.com

The Line 6 Relay G90 Wireless System impresses with its solid build, extended range, and user-friendly design. Its ability to simulate cable tone is a standout feature, offering flexibility for tone purists. The switch to AA batteries and a longer battery life are practical enhancements. While the sound quality improvements over previous models are subtle, they ensure reliable performance across various setups. The only downside is the omission of additional antennas for diversity functionality, which must be purchased separately. Overall, it’s a compelling choice for going wireless without sacrificing sound or convenience.

20 bazzilion bands all in a tight 1/4 mile area, and i didn't have any problems

That is saying something, again, as they always say, the tone will be affected no matter what wireless you use but this one at least allows you to shape it a little. Completely happy with it. Except how it tastes, it just tastes like metal and paint.
