thanx for sharing...but can I ask why the disco lights?

Well the first six minutes or so showed him playing a 670. I quit watching at that point.

Thanks for posting.

You can always learn something from these videos.

Sometimes I even learn "what not to do".

Don, that's what I thought, too. However, if you look carefully, the S670 is mounted on top of the S770 which makes it look like he's playing the S670 from the frontal shot. If you forward the video to 1 minute and 2 seconds, then, you can easily see him playing the S770, because it shows him from a side view.

The reason he has the S670 on top is that in another video (which I haven't posted) he's demoing the S670.

You're welcome! I'm glad you found it useful.
