i have a usb audio interface for my guitar so i can use various software and the output is a 1/4 headphone jack. if i plug this into my guitar amp i can hear what i would describe as data interference. if i use a set of headphones i do not hear this noise, so i figured i need to alter the signal so i don't hear any interference on my guitar amp.
Can anyone help me sort this out please
