The replacement studs and other items came in from Stew Mac ($100 of stuff from them fits in a very small box). After installing them (lots of banging) I tested and you can see how the Graphtech bridge doesn't exactly fit in the Floyd rout. It has a more square flange, so it is hitting the rounded edge. Squaring those off with a small Dremel sanding drum more should take care of that. The weird part is that he back of the bridge doesn't fit on the treble side. I'll have to take off a little wood with router there.
I got a bit worried that the bridge was shifted too far to the right and would mess with string alignment, but I used a string to see how it would work and there doesn't seem to be a problem. Since testing that put some hardware on the guitar, I figured I would mock up the layout to see how things looked.
The pickup rings are chromed brass and not magnetic, and shouldn't mess with the sustainer (shown in the neck ring). The EMG 89 for the bridge is still in the old guitar. The knobs will be Volume (pull up to activate tuner), Tone (pull up for single coil), Piezo Volume (pull up for alternate tone), and Midi Volume. There will be a couple push buttons for Midi program change up/down above the back knob and two toggles for the sustainer in front.
