This is by far the best sounding wireless I've ever used. As a bass player with active pickups, traditional wireless tend to distort. With this system their claim that it sounds as good as a direct cable is spot on. I cannot tell any difference between the two. I was planning to buy the G50 system based on price as I really wanted the G90 but didn't want to pay that much for it. The G55 gave me exactly what I was looking for, front facing display that I can easily see when perched on top of my stack, plus an extra 100ft range for only another 50 bucks.. Testing against interference trouble spots my old wireless had has proven to be unaffected with this wireless system. If you're on the fence, get one, you won't be disappointed...
