This is a pretty easy straight forward question. In your opinion what are the best 6 inline locking tuners and what makes them better than the others?
hipshot griplock. Most locking tuners are the same. I like the hipshot because they are open back and lighter.
I can tell you ones to avoid - the Gotoh self-locking type. They are small and neat and they work fine, but changing strings is very slow because of all the knob winding and mucking about necessary to unlock them.
