Hello everyone, I have this problem that I hope you can help me solve. I just purchased irig hd x and also purchased the full amplitube app on app store. Connecting irig hd x to the iphone (I have tried 3 types of iphone: 15, 15 pro and 11) the signal in both the amp output and headphones, only comes out if the FX/THU switch is on THU obviously making the natural guitar signal come out., As soon as I set the switch to FX, everything goes silent. What can I check? Thank you.
