Analog Guitar Signal to Midi Note to Blutooth to Smartphone

Hi! Helpers always want as much documentation as possible.
However, looking at videos, consumes significant time. My opinion is that video looking makes You loose potential helpers.
Try to give as many engineering facts as possible, here.
Don't be lazy, make it easy for You and then, harder for us. It's a negative approach.
For all special equipment, post links to the data sheets. Data sheets seldomly show up in videos.
All controller projects can be split in 2 parts, managing the needed hardware and what to do with the used hardware.
New games, new bets....
