Out of curiosity, what point are you trying to make? I believe most people know about the Tutmarc instrument; and, as you have said, the Roberts book gives a pretty even handed summary of it.
If you read the Roberts book further, Jim doesn't really treat Fender as anything more or less than what it actually was. That's why I've been a little surprised by some of the posts and continue to encourage people to actually read the book. It's pretty simply what just happened. For the most part.
I was responding to an earlier post that said it was highly likely that Leo did not know about the Tutmarc bass. My post was describing a scenario which made it highly possible he could have. I was connecting dots.
I need to re-read Roberts' book, as book. I read the serialized version in Bass Player -- the "pre-publication" version. I'm sure there were changes before the book came out.
Roberts clearly whiffed on the Regal Bassoguitar, and I question some of his comments on the origin of roundwound strings; but aside from these things I give him high marks.
