Great video, and discussion! It does sound a lot better after the mod.
Considering that this guitar comes to us from the early 50s, you have to wonder where the designers were going with it, and how it would have sounded when it was new. Hard to imagine they were designing it to be able to drive an amp into distortion. Rather, they'd probably do what they could to avoid that.
But that was then, and this is now. And what we expect from an electric guitar today is very, very different.
Your effort in putting the videos together is awesome. And so is the guitar.
