Schaller Lockmeister 6 Tremolo C 37mm

Got the lockmeister for a Kramer baretta special, which moded to the original baretta specs. The tremolo itself is top quality, nothing to mention there. Big mass on the trem block also, so it flutters bery easily - maybe too easily sometimes (i can hear a slight flutter if i hit hard the G string). My only gripe is on the nut: it kept snapping off my high e string when i tightened (not overly tight) the nut lock screw. Eventually after some sanding of the B/e sting nut lock, it stopped cutting the string. Just something to be aware and not get frustrated if the same happens to you.
