Shure GLXD16+

I have already used it in dozens of rehersals and 3 gigs, even use it at home while practicing - without any issues whatsoever: No dropouts nor interference, provides clear transmission with great dynamics. Both sender and receiver are very strudy construction, feels indestructable. Battery can last 6-8 hours, and charges fast, so I felt no need to buy a spare one. The remaining battery life is indicated on the receiver nicely, so no unpleasent surpises while gigging. Built in tuner is easy to use. The clip of the sender is strong enough to attach it to the guitar strap and hold it there without any issues. My bandmates use the line6 g30, which is significantly cheaper, but the difference shows in the quality as well.
