I’m impressed with the Joyo JW-02. It was easy to charge with the included cable and AC adapter. After that, I plugged the receiver into my pedalboard and the transmitter into my bass guitar, turned both on and without any configuration it worked flawlessly.
As a bass player, I was concerned about the unit clipping the low frequencies as many products for guitarists don’t necessarily work well for bass players. My signal was not affected, low end was still there. It offered great range for me to be untethered, did not interfere with the wireless of my in ear system, our band WIFI or our guitarist’s wireless system.
