Thanks much to everyone for sharing your helpful comments! I just saw them yesterday when I decided to check my messages. I’m feeling kind of sheepish because I was waiting around, expecting to see an email notification that someone had seen my question. After a week, I began thinking, hmmm, I thought there would be at least one response. Wow, what a wonderful surprise when I finally checked my messages! I’m following up the leads you all mentioned and that video by Tony was the one I was thinking about. Thanks again! And I will never again doubt the helpfulness and sincerity of this community of guitar geeks. (And I will check my messages more often!)
