The kick ass was a perfect drop in replacement for the stock bridge on my Washburn T-24. It took only minutes to install, and it was an instant improvement. Easy to intonate, although, it was a bit tight to get a screwdriver between the end of the string and the recess in the bridge, maybe allen head screws could be the answer. Love the adjustability, recessed screws, and the rounded corners. My old bridge had height adjustment screws that stuck up and always annoyed me.
