I’ve been looking these as a possible wireless solution for a keyboard. I know they are designed for guitars, but a four pack is available comprising two transmitters and two receivers. They run on the 2.4 ghz band and there a four channels to choose from. The thing is, will they wok as a pair for a keyboard with the receivers panned left and right at the mixer? Has anyone any experience with these units? There are lots of reviews but nothing on keyboard use. Here is a reference: https://tonereport.com/reviews/xvive-u2-wireless-transmitter-and-receiver
