Wireless Freedom, Cable Tone!

You're a guitarist. So, what do you want from a wireless system? You want your rig to feel and sound like you're playing through a cable! Fortunately, Line 6 gets that — and that's why the Relay G Series is for you. Each member of the series — the Relay G30, the Relay G50, and the Relay G90 — offers up Line 6's impressive "Virtual Wire Transmission" technology. In short, it means these systems are designed to give you the full-range sound, response, and range you expect from your guitar rig... just like a high-quality guitar cable. There's even a Cable Tone Simulator feature that lets you match the sound of your Relay wireless system to the sound of your favorite cable... so now you don't have to compromise your tone just to go cable-free. What else do you need to know about the Relay G?

Well, when you want no-compromise sound in a rugged, rackmountable form factor, the Relay G90 system — the one you're looking at right now — is the way to go. It features 12 compatible channels — plenty of channels for your weekend gigs and even most festival shows with tons of other guitarists. The Relay G90 also gives you 300 feet line-of-sight to move about the stage — that's more than enough to get interactive with the crowd and the rest of your band.

All in all, the Relay G90 system gives you a rock-solid wireless solution. You touring musicians will appreciate the IEC power connector and the internal switching power supply — that way when you head overseas to tour, you won't have to leave your wireless freedom behind. This particular system also features an XLR output in addition to the 1/4" standard output, so you can pipe your signal out to a recording interface or into the mixer to beef up your sound through the PA.

Worry-free Wireless!

We wanted you to know that all of the wireless systems you see here — and all of the wireless systems available at Sweetwater — are 100% compliant with the Federal Communication Commission's new rules governing wireless systems. You can be confident that these systems will work safely and within the permitted frequency/power ranges, just as they are. However, please be aware that by choosing to use systems that operate in the 700MHz range or by modifying a new wireless system you receive from us, you may cause your system to operate outside the FCC's new guidelines. If that's the case, you may need a license to operate the unit. To find out more, visit the FCC's wireless microphone website at or give them a call at (888) CALL-FCC.

Great gear

bought this unit and love it. top quality equipment and support. always helpful,

Absolute Best Wireless for gigging Musicians

Crystal clear, perfectly quiet, excellent range, rugged construction (both transmitter and receiver are metal), and so easy to use my Grandma could have done it. Don't worry about the cost. You will be glad you paid it and this is what they're talking about when they say "You get what you pay for". These Line 6 G-50 and G-90 series absolutely rule.

Competes With the Rest

I was blown away by this unit! Great battery unit and it's a shame no one else as paid much attention to it. Sennheiser makes good stuff but I had to go with this one. It gives awesome tone, great functions, 12 channels, awesome battery life (800 minutes). Pick one up if you got the coin.

This is the best wireless! PERIOD!!!!

The dynamics, range and tone of this unit is insane. The freedom of plying unleashed, so to speak, is frickin awesome. Any place, any stage, this unit will deliver the sonic rockin shredding you'll expect from your set up. Plain and simple, IT KICKS ASS!!!

So far incredible!

I've been messing around with these wireless units for many years without having much luck. Some work well but alter your tone so much, you have to re-tweak your tone totally just for wireless use. It really is a drag how much they compress your tone. If you are a serious guitarist that has spent years tone chasing and finally have the sound you love, you have 3 options. 1. Use a good cable. 2. Buy what the pro's use and spring for the Sony...which is the price of a downpayment on a car. 3. The line 6 G90. I have had just about every wireless unit you can think of. Samson, Beyer, Shure, AKG, Sennhehiser, me when I tell you, I've really put some time into this. Well, I got my G90 last week and I'm totally in love with it. The cable selection option is truly incredible and DOES make a difference. The reception is great, the signal is clean and I didn't even hook any antenna's up and it still worked great! I'm currently using the antenna's in the back of my rack right now. I walked up stairs, all around my house, (my house is huge) in my heater room, in my attic, outside, behind my deck, in the front of my house...this thing would just not drop out or give me any artifacts at all. One of the other guys that commented on this unit mentioned issues with his re-chargable batteries. I've had no issues with mine.(the top of the line Eveready re-chargables.) This unit is just amazing. Don't even procrastinate if you really want a killer wireless. Now there is one issue that was really bothering me. The unit (at least mine does this unless it came here broken?) has a strat-type hum noise. It sounds like a 60 cycle hum minus the low end. You know that strat type buzz you get under lights? It's exactly that and I'm not using a strat. I can't get this to stop no matter what I do. As long as the unit is plugged in (it doesn't have to be turned on) and routed through your gear, you will get this noise. I've tried it in different sockets and even in my power conditioner. It does not remove this noise. The fix? of those little 3 prong to 2 prong adaptors that lifts the ground. I don't like to use those things, but I'm going into a power conditioner so hopefully I'm still protected. But the ground lift plug worked perfectly and I have no noise at all now. I have to check with my rep to see if all these units do this by default or maybe mine has an issue somewhere. But other than that little thing, this is by far the best wireless unit I have ever used. If lifting that ground is my only issue and I get the tone I get from my cable, I'm right where I want to be. So definitely check this thing'll be happy you spent the money on it. :)
