The Line6 G30 Relay is an all round inexpensive guitar and bass wireless system that performs as good as any system the market has to offer. It delivers clarity of tone without delay and no audible loss of tonal quality at any venue anywhere.
I have used this system for my bass for many years now as have my fellow band members for their guitars with no issues to note.
Having recently purchased two more transmitters so each bass has one ready to go at the side of the stage when needed.
Flawless transition between guitar changes, simply turn off the one your using, change the guitar and switch on the new one - as simple as that.
Have thought of upgrading to a different system a few times but have no valid reason to do so as these perform so reliably in all conditions.
Weather on your amp or as I do, have it on my effects board so I can monitor signal strength it has never let me down be it small humid indoor stages or large cold and windy outdoor festival stages.
Neatly designed and simple to use it looks great on a pedal board. The only floor I have to point out is the transmitter clip. Needs to be removed if using a holder and isn't the greatest design if using the clip. They always break off. Even when removing the mounting following manufacturers instructions the clip holder breaks but this is just one tiny inconsequential flaw. They've all gone on mine.
I would recommend this system not only to anyone wanting to try a wireless system for the first time as it is inexpensive and delivers a professional sound well above what you would expect to pay for one, but for those wanting to upgrade this system packs a punch well above its weight.
