I'm a guitarist, guitar collector and general guitar nut.
I run several websites about guitars and have just set up a new one to promote a guitar teaching aid called the Space Trainer, invented by a friend of mine who is a guitar teacher. http://guitar-gizmo.com . It won't make our fortunes but hopefully will make life easier for guitar teachers and students.
If anyone else has a guitar-based invention they want to sell, let me know!
