Hi Mathew,

Our new LB63 bridge is not based on a Gotoh bridge. It's our own design, and we combined ideas from several bridges to offer a combination of features unique to our bridge. These include:

- hardened knife edges, with lateral positioning determined by one blade only (to optimize the fit on a wider variety of guitars)
- angled fine tuners to provide more hand clearance for palm muting
- set-screw type tremolo arm lock to permit fine-tuning the tension to your preference

Our beta testers have had nothing but positive feedback using the LB63, so we're confident about showing this product at NAMM in January.

Let me know if you have any specific features you'd like to compare.

Here's a few of photos for you. One shows everything that comes with the LB63, but this gold bridge is actually an early prototype (with the old Graph Tech logo). The new (black) one has the new logo, and we've changed the way we do the trem arm tube, from a nylon sleeve to a steel sleeve with a nylon-tipped set screw, for more responsive action. The other bridge next to the black LB63 is a Hipshot bass bridge, nothing to do with Floyd Rose.

Edit:About the knife edges!

Its not a single knife edge. They're both standard knives, just like on gotoh trems. The flat edge is still sharpened just like on an ibanez edge or something like that. It basically means that you don't have to have exactly perfect stud spacing to have the bridge work properly. If you have 2 curved knife edges, then even 1mm out of alignment on the studs can result in a bridge that will never, EVER return properly to tune.

The flat knife edges do wear a very small amount more than a curved knife edge, but they can be really easily sharpened with just a small file. Get it butterknife sharp again and it removes any sense of binding within the posts. THeres even a guide to doing it on IbanezRules.com

It'll actually be easier to do on this bridge too, because the baseplate on the Edge trems are thicker and angled around the knife edges, so you can't get a really good filing angle. This doesn't have that so you can sharpen it really easily. (Although assuming its as hard as a floyd or Gotoh knife edge, it won't need sharpening for a good long time. 3-5 years even with heavy tremolo abuse.)
