Relay G10 USB input poor design in Relay Digital Wireless Posted October 15, 2018 My G10 USB connection totally sucks!!! - I had to return one because the USB jack was loose and it would turn on and off and lose connection to my guitar throughout the gig. They swapped me for a brand new one, and now this one is doing the same thing. Does anyone want to buy mine? I am getting rid of it.
