The Chords of Orion YouTube channel is an invaluable resource for modern guitarists. Bill Vencil’s focus is ambient music, but he covers gear of interest to any modern guitarist. I was unaware of the Joyo device. It makes me wonder if the EBow patent has run out. I compared the Aeon and the EBow in my Electronic Musician column, but a head to head (to head) video comparison is very  welcome.
