Line 6 Relay G90 Digital Wireless Guitar System

Superior Sound - The Line 6 Relay G90 provides a pure signal. Its clarity rivals that of the highest-quality guitar cables. Instead of being transmitted as analog waves, which are prone to degradation and loss, the signal is converted to digital data at the transmitter and back to audio at the receiver. The result is no signal degradation and no loss of either high or low frequencies.

This model has 12 possible channels and a range of 300 ft - a great, affordable wireless system that's up to professional standards.

Here's what Line 6 say about the Relay G90 System

Relay G90 redefines the wireless experience for guitarists and bassists. Its superior sound, professional dependability and refreshing simplicity are unavailable from other wireless systems.

Superior Sound

Relay G90 provides a pure signal. Its clarity rivals that of the highest-quality guitar cables. Guitars get a beautiful high-end sparkle and basses get a thunderous low-end punch, even at distances of up to 300 feet. Traditional wireless systems compromise their sound by rolling-off crucial high- and low-end frequencies and compressing their signals. Relay G90 offers superior sound with full bandwidth and zero compression.

  • 300-foot range, line-of-sight
  • Broad 10Hz - 20kHz frequency response
  • Superior 118 dB dynamic range
  • No signal compression

Professional Dependability

Relay G90 broadcasts its robust signal over the 2.4GHz band. This keeps the signal free from many kinds of interference. For added security, Relay G90 employs exclusive signal protection technology: each channel broadcasts an encrypted data stream on four different frequencies simultaneously.

Traditional wireless systems, on the other hand, are susceptible to dropouts, static and many other kinds of interference. They broadcast over congested UHF bands and their signals can be affected by interference generated as far away as 100 miles, or more!

  • The 2.4GHz band is optimal for professional guitar wireless systems
  • Encrypted data stream for added signal protection
  • Each channel broadcasts on four different frequencies simultaneously

Refreshing Simplicity

Relay G90 is easy to use. Bright LCDs and LEDs on the transmitter and receiver display all critical system functions including power, status, channel number, battery life, and more. Plus, Relay G90 finds open channels right out of the box. No scanning, no searching, no hassles.

The low-profile transmitter remains out of the way of your performance. Plus, it's rugged, lightweight and it conveniently features a standard 1/4-inch input. The rack-mountable 1RU receiver has a clean and streamlined interface. Antennas can be connected in the front or rear of the unit.

  • The system includes the transmitter, receiver and all necessary accessories including antennas, guitar cable, power supply and batteries.
  • Lightweight, low-profile transmitter; easy-to-read rack-mountable receiver
  • LCDs/LEDs display all critical system functions
  • Find open channels right out of the box

Attached to Your Guitar Cable?

For players attached to their cables, adopting a wireless system introduces many questions: What will it feel like? Will it change my sound? Relay G90 sounds just like a cable, but it can also sound just like your cable. Relay G90 features EQ settings to match the frequency response of your guitar cable. Switch between Relay G90 and your cable without having to change the settings on your sound amp. Different players use different cables, but all players can use Relay G90.

  • EQ settings provide guitar cable frequency responses
  • Switch between Relay G90 and a cable without changing your sound

The Wireless Revolution

Relay G90 is proudly ushering in a better-sounding and more dependable era of wireless guitar systems. It will inspire you to explore new areas of your music and the stage.


  • 300-foot range; 12 user-selectable channels

    Absolutely brilliant product

    Amazing Product!

    I deliberated long and hard about wether I could justify spending £500 on a bit of kit just so I didn't have to have a 3/5m cable dragging behind me. But with Andertons Interest free payment option and 14 day money back I decided to dive in!!

    Now some people dont like Line 6??? Don't know why??...so let me say this...WOW...what an amazing pice of kit...it has blown me away..it truely is superb. First off I'm 40 yrs of age and have been playing seriously in cover bands for 15 years. The most important thing to me is 'tone' as once you have found your tone you want to keep it...this was my biggest worry with wireless. All I can say is that I've had this now for 5 days and it does NOT affect your tone in any way!! I've a/b'd the unit and compared the tone with my usual 'monster' cable...couldn't notice any difference what so ever!!

    The unit is plug and play right out of the box..a baby could set this up its simple, its also unbelievably well built, the reciever (main unit) is beautifully made, simple sold and with different led light options looks stunning. The transmitter is also superb, solid metal, light weight (you dont even notice that its on your guitar strap!) 8hrs battery led countdown...and a nice solid rubber 'stubby' antenna..not a horrible dangly wire that can be ripped out! Brilliant.

    Only minor gripe for me??..is no output on the front of the unit (its on the back) so I have to cut a hole in the lip of my rack to feed the cable through to the input which is on the front of my pre amp (Digitech 2120)...though many modern pre amps now have inputs front and back, also the guitar jack is a straight one and not angled which I prefer...not a problem if you have a fender I guess..and perhaps the lead itself is a little thin??...but you can buy an 'upgraded' jack and lead for this unit from a certain on line 'auction house' which i have done.

    So basically if your looking for a wireless system then this is the ONE to buy (I would assume that the slightly cheaper G50 G30 are just as good) but I have a rack set up so this was the one for me, Oh its digital also so no interferance either...and just incase you were wondering I took a walk down my road over 300 metres and my amp was still playng away...awsome!

    Line 6 have got this so right its untrue and is probably the reason that most pro bands are using them. Treat yourself...you deserve it!

    Excellent Wireless System from Line 6. I have always had the problem with tone suck from previous other wireless systems but I don't get that issue at all with this (you have the option to put tone suck back in! Just select your normal cable length). Very Easy to use and setup. I purchased an extra wireless pack so I have both of my guitars plugged in and with one touch of a button from the front of the unit they are instantly connected and I can flick between the two. No time wasted plugging cables in and out of guitars.

    Really great unit and I would recommend this to anyone. Great for Soundcheck's if your doing your own sound as you can stand miles out front.

    The G90 is a fantastic piece of kit.

    I was torn between the cheaper varient the G50 and this rack model. To me the rack just made more sense seeing as my entire guitar setup is rack based. I have rigorously tested its features and capabilities.

    The only other Line6 gear i've owned is a POD XT Live which lasted me years and years playing all over the country, so im expecting this to be the same.

    The battery life is phenomenal and the fact that the transmitter takes AA batterys is a god send! The transmitter itself seems bullet proof (much like the receiver as well) however my only concern is the cable. The connector that plugs into the transmitter seems like a custom line6 one and it may be difficult and/or expensive to replace.

    Signal is great and (providing there're no thick walls in the way) can stretch for aaaggeesss, more than you would ever need (but it's nice to know its there).

    Onto the receiver itself. 1U in size and as sturdy as you like, it feels like a pro piece of gear. The detachable antennas are awesome. One thing that surprised me is the ability to plug the antennas into the back so they're not sticking out the front! The LCD display on the front is bright and easy to read on stage amongst the mist and darkness. Another really cool feature is the ability to change the colour of the display on the front.

    The price may seem a little off putting when compared to cheaper units. But after seeing first hand what a cheap wireless can do (poor sound, poor construction etc...) im glad I went with this, and would definitely buy one again if need be.
