I have a question. My cousin has this device that enables him to play his guitar on the pc from his amp. I have a jack in my amp for this, but I don't know what they're called. Does anyone know?
are you talking about a line out?
I think he's talking about a usb audio interface to plug his amp in his computer
Yah, it's most likely a USB interface like an AudioBox (my favorite) so you plug your amp in and voila, it gets rid of most of the latency that occurs in a regular microphone input.
