so i have a GK MB500 head which has a built in DI and a GK 410MBE-II cab. i went trough my pedals into my bass head and then using amicrophone cable with one XLR end plugged into the DI and 1/4" jack plugged into a 1/8" jack adapter and plugged that into my laptop's microphone input. ran cubase and couldn't hear anything. feels like a dumb question, but what im a doing wrong?
