Leave do a question... What it takes for record with USB? Cause in the box there arent any USB cable or something like that...
Apparently the digitech bp355 doesn't come with a UBS cable. you'll need a UBS cable to record music on your computer.
another option you can do is if you own a mixing board like a tascam portastudio mixing board, you can record music through there and export the tracks on to you computer. that's what I did when I record music with the digitech bp355.
