Nilsson Shmilsson!

You could make a tent with all that extra denim.

You look like the bad guy in a Stephen King novel!

For a long time big bands used banjos because they had the volume advantage.

I think your terminology is a bit loose here.

Lots of big band guitar players used “electric guitars” — they played guitars that had pickups and amplifiers for additional volume. Most of those guitars were full-depth hollow body guitars with pickups. Think the Gibson ES-175 or a D’angelico archtop. Someone else pointed to Charlie Christian with Benny Goodman in ‘39, but there were other earlier ones.

I think what you’re thinking is electric guitars with more of a rock & roll sound than a jazz sound. You can find examples of that not so much in the big band era, but in the jump blues genre (think Louis Jordan or Louis Prima), where you can here guitar parts that are proto-rock and roll. In fact, Chuck Berry lifted a riff from Carl Hogan, Jordan's guitar player, for Johnny B. Goode.

Here's a sample of Louis Jordan to try out: https://www.youtube.com/watch?v=m7M4thNT_EY

I was lucky enough to see her at a music conference where she was keynoting. I don’t remember much of the speech, but I do remember who doing this a capella. Spingles just thinking about it.
