We were set up to make more videos of strings, but that wasn't possible. I've gone into that before. We thought the other videos of the middle, treble, and high treble would be useful but we weren't able to complete them. I am pleased that what we did observe is being studied and presented. By the way I will be presenting an all day seminar in Lincoln, NE on March 20th at the Central West PTG Regional Seminar. Much of this information will be discussed.
