I've reviewed many wireless guitar systems in the past from super budget to higher-end systems. They all had good and bad points about them but one aspect that I found many had in common was the lack of ability to deal with noise interference.
When reviewing the Phenyx Pro PTG-11 Wireless Guitar System, I noticed no additional noise. I was very pleased to see just how well the system dealt with noise overall. I feel this system is a great prosumer wireless system that is also well built and offers some very nice features not normally found on other similar systems.
