I was recently asked in email if I could write some articles on guitar technique. In my reply I said that's a somewhat complicated request because describing technique in words isn't exactly easy.
Sometimes guitar sellers unload these things just to get rid of them. There are certain things you have to keep in mind if you decide to get one of these.
In reality I grew out of most of these things in my mid-to-late 30s, but I think most guys give this stuff a miss after passing 40.
