I can't tell from the video as the 2 models, C414 XLS or XLII, look very similar it could even be an 414EB as I was looking at the colours and the EB has silver? Not sure of the colours of the old versions.
One thing this points out is how simple it is to mic and record acoustic guitar and vocal, the number of threads that turn up on this forum asking how to mic the guitar? How to record guitar and vocal? Why does my recording sound so bad? Well, this is how you do it, stick the mic in front of the guitar, stick a mic in front of the singer, very simple.
Then with good instruments, good playing, good singing and talent, record.
