This is a SPST switch that places either the bridge or neck in parallel with whatever else is selected in parallel.
This is a DPDT switch that is completely unrelated to the rest of the wiring scheme.
I presume that this places the neck in series with the middle in position 4. Does it also place the middle in series with the bridge (regardless of whether the bridge is in internal parallel or series) in position 2?
What happens in positions 1, 3, and 5 when the guitar is in series?
What does the "Seven Sound Strat" switch mean when the guitar is in series?

A SPST switch, which is an ON/OFF switch, is a subset of a SPDT ON/ON switch.
A SPST ON/OFF switch is essentially a SPDT ON/ON switch with one end terminal missing.

Well, I can't actually tell what rabidgerry wants as
may mean that he explicitly wants to have to put the lever switch in positions 2 and 4 as well as change the toggle (DPDT) switch,
or it may mean that he wants the parallel pickup configurations that occur in positions 2 and 4 to be in series rather than in parallel, in yet to be specified lever switch positions.
The S-none designs, as well as the Fender SSS S-1 design selects
the bridge in series with the middle in position 1,
the bridge (in parallel with the "special cap") in series with the middle in position 2,
the neck (in parallel with the "special cap") in series with the middle in position 4,
and the neck in series with the middle in position 5.
The only variation is in position 3.
If you like the bridge in parallel with the neck in position 3, and the bridge in parallel with the neck, both in series with the middle in alt position 3, use the Schaller Mega Switch "E" version of the S-none design.
If you must have the middle only in position 3, and will settle for the middle in series with the "special cap" in alt position 3, then use the Fender standard 5-way lever version of the S-none design.
If you must have the middle only in position 3, and the bridge in parallel with the neck, both in series with the middle in alt position 3, then use the Fender SSS S-1 design.
We already have more design options than we have guidance as to what is actually desired.
Maybe he'd be happy with the Mike Richardson scheme?

The middle pickup will be selected alone or with one coil from either the bridge or neck pickup. These are 6dB lower in output than the full series humbucker configurations. Try it first and then decide. If there are signal phasing issues with the selected single coil on the bridge and neck pickups relative to the middle pickup, disconnect the wire from the 5-way lever switch that goes to the back of the volume pot and connect it to the hot terminal on the volume pot. This will short the other coil on the bridge and neck pickups and effectively select the coil of opposite polarity relative to the middle. Besides, it's way easier than rotating this space-time-brane instantiation (the entire universe).

I reiterate: " If the highest frets (those located over the neck pocket) have the clearance issue, no amount of seasoning/tension, truss rod adjustment, or any such measures will have any effect whatsoever." Do the highest frets on the neck have the problem? If so, shimming (angle modification) of the neck heel is required first. What is the heel thickness of the neck (from the back that fits into the pocket to the top of the fretboard)? What is the heel pocket depth? Is the bottom of the neck pocket coplanar (parallel) with the body top? Does the neck pocket have a tilt to it (such as for a TOM bridge)? Is the finish on the neck heel an even thin layer or does it get thicker closest to the neck heel bottom? All of these questions go to the coplanarity of the neck/body junction. USACG addresses the issue of coplanarity using "fall-away". www.usacustomguitars.com/neckfeatures.htmlIt would appear that the truss rod is not "maxed out", but is at its minimum adjustment. A single-acting truss rod has only one effect: to counter the bowing of the neck from string tension. Is the neck level when the strings are not under tension? Are the frets level? Here is some information on neck pockets and heels. Select "Will it Fit My Guitar". www.warmoth.com/Guitar/Necks/Strat_TotalVintage.aspx

I would like to (re)point out that the 3 Single Coils and The "S-None Switch" design uses either a Schaller mega switch "E" or a standard Fender 5-way, both in conjunction with a DPDT switch to effect both bridge and middle in series and middle and neck in series. No 4P5T super switch is required.

If the highest frets (those located over the neck pocket) have the clearance issue, no amount of seasoning/tension, truss rod adjustment, or any such measures will have any effect whatsoever.
It's a simple mechanical engineering problem. If the bridge saddles need to be too high to effect higher fret clearance on these frets, only the saddle height relative to the plane of the frets at said high fret location will effect the proper relief. Bodies and neck heels are not adjustable in co-planarity aside from shimming or pocket pitch.
As D2o indicates, the neck must first be shimmed to effect the desired saddle height relative to the plane of the neck at said high frets. Once this is done (and it must be done first), then the adjustment of the truss rod will be effective. To effect this, I use a capo to ensure that all strings are pressed against the highest possible fret just off of the body.
My approach has always been to effect the desired saddle height first via shimming if necessary. Then (and only then) I adjust the the truss rod, which only has effect on the frets that are not directly over the body, to increasing effect as one goes down the neck.
I've seen too many necks ruined through wood compression from truss rod abuse. I've bought too many guitars from GC that were on fire sale from the absolute lack of understanding on the part of the sales noobs/jubblies on how to set up a guitar.

The drawing is both a wiring diagram as well as a layout diagram as the components are in the positions that one would see when looking at the underside of a right-handed Strat pickguard. The numbering is irrelevant.
The initial standard 5-way lever switch diagram is pretty much what Fender sells in most Strats. The S-none modified drawing shows the wiring changes effected for the conversion.
I would start with a 0.022 uF film cap for the "special cap" (I never use ceramic caps).

The first version of the "3 Single Coils and the "S-None Switch" design does the following: "The Mega Switch E alone realizes the following combinations, all but #3 are the same as the Fender ones: 1. Bridge 2. Bridge + Middle 3. Bridge + Neck4. Neck + Middle 5. Neck I personally prefer the B + N rather than the middle in position #3 since it is more Tele-like. With the addition of only a DPDT switch (the S-1 is a 4PDT switch), the following additional combinations are realized, exactly as my Fender Am Dlx SSS Strat does: 1. Middle * Bridge 2. Middle * (Bridge + "Special Cap") 3. Middle * (Bridge + Neck) 4. Middle * (Neck + "Special Cap") 5. Middle * Neck" The second version of the "3 Single Coils and the "S-None Switch" does the following: For those that want to use the traditional Strat 5-way switch, here's a design that uses the Schaller Mega Switch equivalent (or the standard Fender 5-way lever switch). "The Mega Switch S alone realizes the following combinations: 1. Bridge 2. Bridge + Middle 3. Middle 4. Neck + Middle 5. Neck With the addition of only a DPDT switch (the S-1 is a 4PDT switch), the following additional combinations are realized, almost like my Fender Am Dlx SSS Strat does: 1. Middle * Bridge 2. Middle * (Bridge + "Special Cap") 3. Middle * "Special Cap" [ different] 4. Middle * (Neck + "Special Cap") 5. Middle * Neck" Each design does 9 out of 10 positions exactly the same as the Fender SSS S-1 Strat that requires a 4P5T lever super switch and a 4PDT switch. Each does 1 out of 10 differently, but only requires the standard Fender 5-way lever switch or the Schaller MegaSwitch "E", and a DPDT switch. I personally prefer the B + N rather than the middle in position #3 since it is more Tele-like, therefore, I prefer the version with the Schaller MegaSwitch "E" and a DPDT PP pot. So what exactly are you looking for as both of these designs "series/parallel a Strat the way that the Fender S-1 switch does"?

My vote would be to leave the bridge tone control in place across the bridge only, and use the neck tone control for the master tone. This is my take on Mike's design. Mike Richardson wiring with phase

A lower (smaller) value cap will act as less of a high pass filter to ground and hence cut less treble than a larger value cap. The lower cap value will effectively raise the corner frequency of the filter.
No bass is cut by a high-pass series RC filter to signal ground, which effectively is a high-cut filter.

It's all related to the electrical parameters of the capacitors. Unfortunately, these are not published except by the manufacturers of these components. These are not published by the vendors of these components for two major reasons; the first is that they generally don't have even a hint of a clue as to what they mean, and the second is that many of them do not want things reduced to actual specifications as this exposure to the "light of day" eliminates their ability to sell things based on marketing manure. No one takes the time and effort to quantify these parameters as little change will result therefrom. Keep in mind that most guitar manufacturer's used the cheapest available components (it's a business, you get to keep the difference), and hence, those special "vintage" components aren't all that special. wolf's links are good in that their limited and somewhat folklore based descriptions are good for musicians (but somewhat horrid for electrical engineers such as myself). The statement that "vintage wire must be used to fully hear the effect" is a poor excuse for fertilizer. Now, the biggest problem with the tone capacitance in an electric guitar is the cable crapacitance. If your pickups sound too "warm", this generally indicates excessive cable crapacitance. This is a good source of low capacitance cable. Low Capacitance CableThis is how you order them. Their web site layout is convoluted at best. Bill (Willi Stich, the inventor of the Fender SCN pickups) actually knows what he is talking about from an engineering perspective (compared to the legions that either just parrot what they read or have Fool's gold to sell). www.wildepickups.com/Wilde_Bill_s_Online_Shop.htmlAdding a plate of ferrous metal (iron-based) will have the effect of increasing the inductance of the pickup and therefore reducing the frequency response. It will sound "warmer". "Whatever metal" you choose is of paramount importance. Ferrous metals will increase the inductance while non-ferrous metals (such as brass) will reduce the inductance. These plates will have effect regardless of the pickup position. Stating that the effect is only occurring in bridge pickups is the unfortunate view of the legions cursed with binary vision. The most effect will occur on a Strat bridge pickup that does not have a tone control since it is in the most harmonically rich position and it does not, er, generally have a tone control. A bridge always-on switch is easy. It does get more complex depending on the series/parallel switching structure. The statement reveals little but infers much depending on what the structure of the lever switch means in this mode. Having a binary switch for bridge always-on and a binary switch for series/parallel infers up to 20 pickup combinations with a 5 position lever switch. I rarely keep wiring diagrams of specific implementations as they are easy to design and generate once the specifications stop "wobbling". I do have some designs in wiring (instantiation form) rather than just schematics (the architectural vision) although most wiring diagrams are quite restrictive of lateral vision and thinking. These both are designs that I personally recommend.

You mean like the original 13 colonies? UPS or FedEx will take it here. How about a JB in the bridge and a Jazz in the neck? Of course, this is my preference for a Gibson SG (all mahogany). I don't know what the Epi is made out of, since sometimes they use "tonewoods".

Different materials will have different tonal effects.
The aluminum sold at the big box stores is generally fairly soft.
Three 1/16" pieces will have less coupling than one 3/16" piece.

From Bill Lawrence's website.
Rating Pickups with DC Resistance
DC resistance is NOT a power rating; it is the resistance of the wire in a pickup's coil at zero hertz, something that only occurs when the guitar isn't played. If some marketers use DC resistance as a power rating for an AC device, like a pickup, then they only show their ignorance. If we use DC resistance as a parameter, we disregard the fact that, due to Pe and other conditions that result in eddy currents, the effective resistance (Rac) is frequency dependent.
DC resistance (Rdc) tells you as much about a pickup's tone and output as the shoe size tells you about a person's intelligence!
Millivolts
The output rating of pickups is generally given in millivolts (mV). Millivolts could be a helpful parameter if all manufacturers would agree on a standard measuring method that provides such data over a wide frequency range. Now, let's say with this information, we plot an impressive-looking graph showing the different output levels at various frequencies -- does this give you a good idea of the sonic character of a pickup? Yes and no. Don't forget that not every guitar is created equal, and neither are the players. We use different kinds of strings, cables, amps and speakers, and a pickup is only one link in a chain that finally determines tone and output.
Inductance
Inductance ( henry) is another valuable parameter for the sonic evaluation of a pickup but requires some basic understanding of electrodynamics. As a general rule, the higher the inductance, the lesser the highs. For example, a traditional strat pickup has an inductance around 2.3 henry while a Gibson PAF has an inductance around 4.4 henry and some of the so-called "distortion" pickups have an inductance above 8.0 henry. With these comparisons, you get a basic idea. Besides inductance, there are other factors that also need to be considered in projecting tone and output of a pickup.
Tone and output mainly depend on the relation between inductance, magnetic strength and the efficiency of the pickup, as well as the relation between the inductance of the pickup and the capacitance of the cable.

It would have been nice to get an email indication that it had been shipped.

I like a tone circuit directly across the bridge pickup and one directly across the neck pickup. This way, they can be used to make the series combo brighter go figure, well, if you ask I'll tell you). I do it here; Mike Richardson wiring with phase. This uses a DPDT switch for mode selection. It does B+N in the middle position, which I prefer over middle only. It's in the The Padouk Caster

So this is a bridge pickup ferrous mass (inductance enhancing) under plate? If so, I don't think that you need to ground it (you generally don't ground the pickup magnets either).
The tape is a good question. The air (well tape) gap will have some influence on the pickup's sound.
Ask Callaham.
