    Comments about Line 6 TB516G (Relay G70/75 Transmitter):

    Love the Relay G70. Run it with 3 transmitters on stage. Works flawlessly. Just pickup a guitar on a change and click the footswitch and start playing with the new guitar with all your settings just the way you want them for that guitar. When I pick up the acoustic and click the footswitch it automatically goes directly to the PA. The transmitter is rugged steel construction and has great range. Latency is the best out there ! Highly recommend this transmitter and system.

    Comments about Line 6 TB516G (Relay G70/75 Transmitter):

    Already had the Line 6 G70 and needed a second transmitter. This is it. Nice transmitter. Nice wireless system with great reception, extremely low latency, and two channels plus programmable scenes. The built in tuner is kind of lame, but it works in a pinch.
