Re: Eliminating all my pots?
The direct wiring doesn't necessarily make "better" tone. As you know, and others will say, a good portion of "better" or not as good tone or whatever, is largely subjective. Go to guitar center and ask them to pull down an American Elite series stratocaster. Some of them have a "passing lane" switch, which ties all of the pickups together and bypasses all of the pots and caps. It's basically, all pickups, balls to the wall. I don't necessarily like it. So "better" is one thing. "Less impedance" is another thing. They aren't always analogous.
With that said, it's possible to do it. Just make sure that all of your pickups are wired in the right directions, and decide if you want them to be parallel or in series, in or out of phase etc. I wouldn't personally do this.. but if I did, in the case of a guitar that had multiple pickups, I'd do a kill switch for each and wire them in parallel.
I honesty didn't read thoroughly enough to know if the guitar you attached a picture of was THE guitar, or what you're trying to emulate.
Another route is to put the on/off/on switches like a mustang for each pickup. That's basically what it does, except you can go in and out of phase then too. (They do come in toggle form). I'd still try out different caps, and keep soldering things until you get the sound you want. (Not the typical cap values that you would normally use, because they assume that you are using a pot) You'd have to experiment with several at many different values. Something will eventually sound good, but would kind of beat the purpose of what you asked.)
Bypassing all of the pots and caps makes it very bright and tenny. Not necessarily better tone.
