Pretty cool indeed. Do you think he's a Clapton fan by any chance?

I guess he might just have been, didn't do too badly although that thumb was way to prominent Lol Might be onto something as far as tuning goes though

It looks like a very cool idea for an album cover.

How cool was that?
But what did we just see? Was it necessary for the camera to be inside the guitar looking out... won't it be the same filmed from outside? And why are we seeing the sine wave? SLow mo? Any science buffs with an answer... where's Wrench?

It probably has to do with the field rate of the recording and playback.

PAL Interlace scanning at 50Hz on Uk tvs fills in all the gaps along with persistance of vision in the human eye and brain in normal circumstances. Phones will scan differently.

I have noticed this phenomenon for quite some time. If you hold your guitar in front of a television and sight across the strings, when you hit the string you should be able to see what appears to be a sine wave. At least it works on American cathode ray tube type televisions.
