Re: Floyd Rose Hollow Points??
I think it's a nifty idea. Probably more useful on OFR, Schaller, Gotoh or similar where the saddle screw is located directly under the string. Modern Ibbys have them set to the side, IIRC, so I imagine intonation isn't as much of a hassle then.
The thing is though (with a standard OFR or any Ibby), that in order to move them you need to loosen the string floopy anyways, especially to move it accurately backwards in micro-increments, and when you do it makes no difference at all that the screw is right under the string.
If after slackening the string a bit you simply use your left hand's middle finger at the front (neck-side) of the saddle to brace it so that when you loosen the screw it's easy to control back or forward slide,,,,,,and just keep your middle finger there until you re-tighten the screw with the right hand.
The old system is already perfect for any well-seasoned floyd guy.
That said, these will likely make things easier and more accurate for those not-so-seasoned floyd guys, and non-floyd techs trying to setup a floyd.
My point= Great product for some,,,,,,complete waste of money for others.
