Hi, I have a VOX VT20X and I want to use the guitar rig 7 program. Apparently this amp has a USB input to use it without the need for an interface. I already installed the latest drivers and restarted the PC when I select Asio driver and technology for the VOX 2ch Audio device. In the configuration it does not work in the inputs and outputs it appears that I have nothing connected, could someone help me?
