Hey Norton, I got one for ya. Growing up a guitarist in the days of vinyl I wore out Peter Frampton’s, “Do You Feel Like We Do” with my guitar. 

I have used BIAB for practicing many times. I would load a riff and try a style moving the tempo to and fro. Then, there were also the music/ear training games that I let me daughter use that helps her.

Although I am not one to toil over a particular part until I got every note correct. You will definitely hear it in my recorded music. My primary technique in using BIAB as a practice tool is to take some of their pre-composed songs, and study the lines in them. This will cause my fingers to break their muscle memory. It is a great resource that allows you to break down, measure by measure, what is taking place in the song. I find that so much more productive than watching a video of a guitar virtuoso demonstrating their wares. That is for the “ooh” & “ah” effect. I need to see notes on a page and music accompanying it to really get better as a player.
