observations from actual usage

 As I mentioned, the "raw" switch does very little that a 1M tone pot doesn't already do.  It's mainly useful just for making sure that your tone never gets turned down inadvertently.

The phase switch is quite interesting on this guitar.  Since the pickups are so far apart, it doesn't really produce the expected out-of-phase tone, i.e., extremely thin and hollow.  The signals from the two pickups are quite different from each other, so subtracting one from the other doesn't result in anything close to complete cancellation; instead, it's just a different tonal mix, certainly a bit thinner than the in-phase tone, but if you heard it by itself, you might not recognize it as out-of-phase.  This is true for both the parallel and series modes; so, you get four usefully different mixed-pickup tones.  I guess this might not have been surprising to me, if I had kept in mind how much the regular position-2 parallel sound, *doesn't* sound like a Strat position 2 (or position 4).  On the Strat, both of those modes are combining pickups which are significantly closer together.  Thus, the out-of-phase variations have more cancellation with a Strat, and thus that stereotypical thin out-of-phase tonality.  You'd need a Strat modified like I do it, or something like the "Gilmore switch", to get just the bridge and neck pickups together, to come closer to the sound of this Bullet.

This is the first time I've played around with series single-coil pickups on a guitar, and it's a good sound, probably useful to many people, especially those who complain that single-coils tend to sound too thin or too bright.  However, it certainly doesn't sound like a traditional humbucker, either.  Again, I believe this must be down to the large separation between the pickups.
