I was out of the house most of the evening, but got a chance to plug the guitar in and play through it briefly. My first impression of the pickups is that they are good, not great. The humbucker is appropriately hot for this type of guitar, and seems to have good clarity. I really need to play through it with various levels of distortion, which I was not able to do last night. The single coils also have good clarity and are fairly bright sounding. I was quite surprised at how much effect shifting the neck pickup back to accommodate the 24 frets has on its tone--definitely less of that typical roundness you get from a Strat neck p'up. But I guess that's to be expected. Again, these are VERY preliminary impressions, as I only had a few minutes to fool around with the guitar.

I also found that while the guitar was in tune relative to itself, it was tuned down about 1/2 of a tone. I was not able to get the guitar up to to standard A440 tuning before the fine tuners ran out of travel. Loosening the string locks at the nut, I tuned up to pitch with the headstock tuners, but this created a new problem--the greater string tension caused the FR base plate to be angled up, no longer parallel to the body. OK, no problem, just need to tighten up the trem claw. Except the trem claw was already screwed pretty much all the way in. So I had to add a 4th spring to the trem, and go through the iterative process of tuning the guitar to A440 pitch and adjusting the trem claw/spring tension to keep the FR base parallel to the body. Took about half an hour to get it pretty much dead on, but such is the reality of doing the initial set-up on a Floyd Rose guitar. I was fortunate to have extra trem springs on hand--GFS should probably include a couple of extras with this guitar.

EDIT: Turns out there's a better/faster way to do the trem spring/tuning adjustment. You loosen the trem claw until the FR plate tilts up, then pull it down and block the trem block in place so that the FR plate is parallel to the body. A wedge-shaped piece of wood would be good for this. Now that the trem can't move upward, you go ahead and tune the guitar close to exact pitch with the headstock tuners and then lock the strings at the nut. Once this is done, you slowly re-tighten the trem claw until the the block falls out. Carefully done, you should then be very close to your desired tuning and be able to use the FR fine-tuners to get it "perfect".
