That is a problem that I've never had with any of mine or those by others that I've played. I have to wonder if the brass bar that the "E" lock fastens into might be a little thin and flexing a bit. I usually use 1/4" thick brass on mine and the "E" locks tight and responds just like an open "E" on a bass without an extension. Just a thought.

My lock is Ebony... When I open and close it the lock nut loosens up I guess... I need to add a washer or something but dont want to make it vibrate at all... If i tighten it up...its good...

I'm referring to the piece of brass that the screw (that passes through the Ebony lock/trigger) is threaded into prior to reaching the washer and lock nut. A thicker brass bar has more area for threads which results in greater rigidity before the locking nut is attached to the end of the screw. The purpose of the locking nut is simply to keep the screw from turning after the correct amount of tension has been applied to the screw (i.e. into the brass bar).
