In reference to the video at the Cowan book fair: The fellow (with the long hair) is Geoff Roehm. He is a luthier who lives in Sewanee, TN, just up the mountain from Cowan. I started building bass guitar bodies on a whim and he was nice enough to let me, my daughter and a friend of his come up to his shop and see some his stuff. He provided a lot of good advise and showed/played a TMB for us. It was the first time I had seen one. I'm 41 and have grown up in the county (Franklin County) that is mentioned in several posts on this forum and had not seen a TMB until Geoff showed one to me three weeks ago. My wife went to school with several Steeles. I'm sure they are grandchildren of the folks mentioned previously.
Now I'm lurking this site daily. Once I finish the basses and a couple of bookshelves I have to give a few of these TMB's a try.
