TLDR: This is an amazing wireless guitar system for the price. The battery lasts me a full 4 hour gig as long as I turn both the transmitter and receiver off in-between sets. Sound quality is great except for the terrifying noise they admit when the battery dies.Full Review:My setup:Fender American Ultra Jazz Bass 5-String Active/Passive switchFender Rumble 500 Watt Amp with Send-Receive effects running through a Zoom B3n Effects PedalI bought this Getaria wireless system after my Line-6 G30 bit the dust during the first night of a gig and I couldn't get it working before the second night. Amazon was able to ship the Getaria 2.4GHZ Wireless Guitar System overnight so I decided to give it a shot. I didn't have high hopes for a sub-$40 wireless system but if it worked for one night that's all I needed.I have been shocked and super impressed by how well this wireless system has performed and my $230 Line-6 system has stayed home for the past few months in favor of my Getaria has been on the road with me for 8 more nights.The Getaria 2.4ghz system is for a single user. I am the only guitarist in my band that uses one. My lead singer has a Shure Beta-58 wireless and the other guitarist uses a Line-6 G3 system. Our three systems don't cause any interference with each other. We also use a Soundcraft Ui24R mixer and wireless system isn't affected negatively by it. I've also used it in a festival setting on a big stage and it performed very well.The Getaria 2.4Ghz has great wireless range and hasn't given me any issues with my active/passive bass guitar. I have been able to wander about 40 feet away and still get a signal from my bass guitar to my amp. The wireless transmitter has no problem working with my bass guitar pickups whether they are in active or passive mode.The sound quality of the Getaria 2.4Ghz wireless is fantastic. I haven't noticed any quality loss between my expensive Line 6 systems vs. the Getaria. I have played live with the Getaria and have listened back to my band's board recordings and have been very impressed by the sound quality it carries. My one knock on the sound is the terrifying noise the wireless emits through my amp whenever the battery in the transmitter or receiver dies. As the battery emits it's dying breath it causes the Getaria to emit a sound I can only describe as something I would expect an alien ship to emit as it's shot down above Area-51. It would be a perfect sound for an M. Night Shyamalan movie.The battery life of the Getaria 2.4Ghz guitar wireless system has been impressive and I've been able to use it for a full 4 hour show as long as I remember to turn the transmitter and the receiver off in-between sets. The system comes with a dual usb-c cord so you can charge both the transmitter and receiver at the same time off the same usb outlet. It usually takes about an hour to charge both devices with the included cord. On days when I accidently leave either the transmitter or the receiver on long enough to kill the battery, I'm able to charge them for around a half hour and they last me the rest of my practice session or gig. I have also left the receiver plugged in and charging while in-use and haven't had any issue doing that. It sure beats carrying around a bag or 9v and AA batteries for my previous wireless systems.Overall I have been very impressed by the Getaria 2.4ghz wireless guitar system and would recommend it to anyone needing a budget wireless system or anyone needing a serviceable spare or backup wireless.
