I appreciate that he is using a left handed clone as yet another tribute to the original.
Les Paul is probably one of the more famous stories.
Most really good music technology innovations are from musicians themselves.
EHV is a world-class player, but the only reason we're reading this kind of story is because of that virtuosity-- lots of folks mess around with their instruments like he was doing, though most aren't as dangerously bad at it.
The stories you hear about folks making new music stuff are usually because the folks are good at making stuff, so it seems more like engineers/tinkerers who happen to play music, when that description might be flipped if we looked at how folks think of themselves.
Heres a video of him demoing his older setup: http://www.musicradar.com/news/guitars/video-local-hs-scott-...
I saw them a few weeks ago and he no longer uses the same setup, but I've always thought it was inventive.
I'm not a virtuoso, but was inspired by some others trying to get more range, especially Charlie Hunter (whose fanned frets are nuts), various metal guys, and the Chapman Stick.
I like the idea of a guitar that can easily reach lower registers. Whilst 7-string (and in Charlie Hunter's case, 8-string) guitars are possibly more versatile, I'm quite partial to baritone guitars. This sounds beautiful to me: https://www.youtube.com/watch?v=t_06O8XnJQo
Talking of unconventional instruments, you may be interested in hearing these microtonal guitars, I think the second one in particular sounds pretty good: https://www.youtube.com/watch?v=iRsSjh5TTqI
Then you can just mix and match parts and build according to instructions to make your own unique sound. Very cool and fun.
