sentences:  The Edge Pro and Edge Pro II differ from the original Edge, as they are able to accept strings with the ball-ends still attached, and have no locking studs.Due to the lack of locking studs, the tremolo is in some ways inferior to the models it replaces; however, the lower profile design and ergonomic improvements mean this distinction is not clear cut.The Original and Lo-Pro Edge are still produced and are available through Ibanez Parts dealers.
