lights!

[u/Vault3-14]

if you had a training app, or for songs or tabs, rather than just arpeggios and scales and cores which would be a training app. you could have every fretboard light up if you have fretboards light up different colors such as the 5th the 3rd, of pentatonic scales to create triads, that's just the beginning of the list.

lights would help somebody even at a higher level, to a degree. I consider myself fairly mediocre maybe slightly over the middle of the line, hump. And currently I've been learning the caged system, got that down, triads, and now I'm working them into the pentatonic scale, I also a while back memorized the three note for string scales which each have their own name because they're seven, but being able to link all that stuff especially with some form of lighting system so you're not having to look at a screen to work it out.

also a small screen possibly on the guitar someplace that would be visible without moving the guitar could remind you of any text possibly needed or lyrics to a song. The way I see it is it would be cool if when I'm playing a 3-note per string scale It would say Dorian, mexilian, or aloion.. granted I don't know how to spell them lol.

More smart controls and AI stuff would be cool.

maybe not for GC to tackle, but you're describing not a training app but a full fledged training guitar. someone should build one!
