OK the BOSS BR-800 is in the house,
Thank you Frank @ http://www.audioworksct.com/....
Now to learn it and do some KB recording, add harmony tracks to songs, etc,..so many great features inside,......
Before hand I purchased the Online DVD instructional tutorial from Pro Audio. I recommend this highly for so many products....very well done and super informative.
I learned so much from watching these first hand. They also make so many other DVD's for different products check it out. Much better to SEE it, then read it, in a manual..
There are many ZOOM Dvd's also I know some people here use the Zoom Units too.
