I have a UR22C and a Yamaha TRBX304. I plugged in a pair of headphones, plugged the guitar in input 2, turned up the headphones, output, and gain knobs, pressed the Hi-Z button, and I’m still not hearing any sound from my bass when I pluck a string. It works perfectly fine on my Fender Rumble too. Additionally, I have a Fender Stratocaster and it works fine when I use it with the audio interface. I have no idea what else to do
