Tried this as a trade offer - how about cash? $8 - 1 set in Chrome that are well used, but working great $14 - 1 set in Black, used just long enough to break in the springs so they're not too stiff Both have been installed, and have a bit of loctite residue on the threads (this is my surefire way to guarantee the nut never backs off). In trade, I'll take Dunlops. I need one set each in black and chrome. Schallers worked great - IMO mechanically more sound but these days straplocks are simply a way to avoid wearing out the leather on my straps and I want to switch all my basses to the same kind - Dunlops are currently in the majority.
