The pickup selector allows neck, neck+middle, middle, +middle+bridge, and bridge as choices, with the combinations formed by +putting the two selected pickups in parallel. The first tone knob controls +the neck and middle pickups, the second controls the bridge pickup. + +After lots of discussion with Robert and listening to many demo videos, the +only significant change to this I decided to make is to use a push-pull switch +variant of the second tone control, wiring it to allow phase reversing the +middle pickup. Phase reversing one pickup of a blended pair yields a "nasal" +or "biting" tone. Here is one of the +[clearest demo videos](https://www.youtube.com/watch?v=VIBHg4kwl2k) +I found of this effect. What I like about this option is that it gives what +sounds to me like an old-school blues kind of tone. + +The other minor tweak I'm considering is "treble compensation" on the volume +control, which DiMarzio shows in some of their wiring diagrams. The idea is +to compensate for the usual loss of treble content when turning down the +volume on the guitar. It consists of an additional 560pF capacitor and 300k +resistor in parallel between the hot and wiper terminals on the volume +control. This may or may not seem necessary once we have the guitar together. More to come!
