Thanks for the offer TTH, but I've got a bag of screws on the way. An Update: I have strung it up and played it, with the pickguard jury-rigged with a few screws for now, although it needs intonation and set-up. But meanwhile, there's good and bad news. On the good side, the pickups sound good and it's dead quiet, much less noisy than my unshielded 3-pickup Strat. My worries about excess noise with 4 SCs were unfounded, the shielding seems to have taken care of it nicely. The bad news: The tone control is wired backwards (why can't I ever get that right?); that's easily fixed. More of a problem is the blend control. At either extreme of rotation, it's fine- that's with 1-2 pickups in the mix, depending on the other switching. In the center detent position, however, the output is cut down to about 1/3 of full volume. In this position, 3 or 4 pickups are in the mix. My first thought was that it was the difference in load between 1-2 pickups vs. 3-4. But it seems like way too much of a cut-off for that to be the cause, and it also doesn't seem to appreciably alter things if I have 3 pickups going in the center position as opposed to all 4. My second thought is that the two pairs of pickups are wired OOP at the blender. If so, I'm getting pretty dramatic cancellation between the 3 or 4 pickups. It doesn't have that typically thin, OOP sound though- it's more like a straight volume drop, like I had the volume set to about "3". At any rate, it's only useable when turned to one or the other extreme, so the pickguard has to come off (yet again!) for some more troubleshooting.

Finally. Got this all disassembled and had several goes at fixing the blend control without success. It just seemed to load the pickups too much as 4 were blended together.
So, in the end I scrapped the blender control entirely and installed a good old Gibson 3-way toggle in its place, so as to give me the 2 pairs of pickups, each pair by itself at the ends and both pairs in the center. So, it's essentially the same, the 2 pairs of pickups are switched via binary tree switching for series/parallel and each coil individually, then the pairs get merged in parallel at the toggle switch.
And all works fine now. The guitar gets sent off to the tech this week for set-up and intonation- something that I'd rather pay to do than do myself!
I will say, after playing with this, I think I've found some interesting harmonic points with the 4 pickups, it sounds quite different than a regular Strat. But I'm also impressed with the quiet- I was worried that even a good shielding job wouldn't keep away the hum of 4 single coils, but it's dead quiet.

Your project is looking very sweet. And the sound samples will be interesting to check out. The guitar gets sent off to the tech this week for set-up and intonation- something that I'd rather pay to do than do myself! As much as we're centered around a DIY forum, newey makes a valid point here. I respect him for making it. I don't know how many butchered "DIY setups" I've fixed before. Truth be told, back in the day when business was better, I farmed out setups myself. Happy Trails Cynical One

As you've got it shown now, N+B and MA+MB will not be humcancelling. I'd probably prefer to have the N RWRP with the B (or vice versa ). I was thinking just that when I looked at the pickup layout in the OP. If there were any out of phase combinations, having like polarities on the Bridge and Neck would be desireable. I think distant spacing gives the best results for OoP. So I could see having the polarities laid out this way. But if all combinations are in phase, Neck and Bridge don't humcancel. I think that's a missed opportunity. Sound Samples soon after intonation . . . I'm sure others would enjoy the samples, but the audio on my computer is kinda crappy. But I would like your opinion on which combinations you find most useful.
