Re: ZR Trem
I like it a hell of a lot, but its very very stiff, and the arm holder is badly designed and is prone to breaking. That stiffness has an advantage in that its very easy to be subtle with it, and also it stays in tune very well. tuning it up is almost as easy as a fixed bridge, whether you change one string or all of them.
(as regards the bar, The threads that the bar screws into are only present on the plastic cap at the end. No metal threads at all. And the nut tends to come loose. Combined, those mean that unless you take VERY good care of it and tighten that nut periodically, you may one day be whammying away, and 'KLUNK' and suddenly the bar is looser than a taiwanese grandmother of 4 addicted to crack cocain in harlem.)
