Hi everybody.
I want to profile a tube amp. More specifically a really metal sounding. I just putted an SM57 in a 4x12 cabinet, I follow the instructions given, mic to return and send into amp input, I have the amp connected to the cabinet of course.
The reference amp is working and everything seems to be ok but after pressing the profile button and doing some noises it just appear an advertisement with an error, which says it has no reference amp or is low volume.
I checked everything, and looks in order, can someone help me??
