Hi guys, Can anyone point me in the right direction for that diagram that explains how to wire up the different 5-way switches strat-style? I have one of those import-type switches with a line of 8 lugs on top and can't remember which wires to solder where. thanks!

looks the same only according to my multimeter my 8-lug config seems to be 321CC321 instead of 321CC123

OK, here's the plan. This is the custom Tele I'm putting together for a friend. We have a Seymour Duncan mini humbucker in the neck position, a SD Strat hot stack HB in the middle and a SD vintage stacke tele bridge HB pickup. These are all 4-conductor pickups and all will have the red and white wires taped together. The scheme below has a 5-way strat type selector with the addition of a DPDT on-on mini toggle swsitch to reverse polarity of the mid pickup. We then switch back to a standard tele-type single master vol and single master tone pot. Anything look wrong or out of place to you electronics gurus with this schematic? The idea is to get a versatile set of tones being able to use the mid pup in reverse polarity to get strat-type rhythm tones as well as full on blends of mid with neck or bridge (as well as mid on its own). On another issue, I recently plundered an old redundant project to find this resistor and capacitor in parallel soldered to the volume pot. I can't remember what the purpose was of this when i first did it, but presume it is a treble bleed circuit. Neither can i remember how effective it was! Answers on a postcard please.

eric, Your intended schematic has a flaw - the red line coming up from the Volume pot goes to the common terminal for the wrong pole! Move it over one lug to the right, that will put it on the correct common terminal for the pole you're using. And the 'extra' components wired to the Volume pot are indeed a Treble Bleed circuit, parallel version. The values are a bit hot for me, I like 180KΩ and 1.5nf, myownself. But that's just me. What you have will work, to be sure. HTH sumgai

Notwithstanding the flaw, I like that drawing, with the colours and all.
To my eye it seems easy to follow and not at all susceptible to misinterpretation.

Thanks guys, dependable advice as ever. Dan Erlwine has a cap and resistor parallel thing for voltage surge protection in one of his repair and maintainance books but I guessed it was atreble bleed thingy. Now finally, any advice on the tone pot cap value for the custom tele circuit? 0.33 or .047 would be about average for this fine array of humbuckers wouldn't it?

I can't remember why I am thinking that 0.033uF would be a nice compromise and work well with your treble bleed ... ... anyway, that's my inclination, but seein' as I can't recall why that's my inclination, I won't be offended in the least when you wisely decide that you'd better wait for sum other gai to give you his input rather than rely on what may be my imagination.

eric, in re: Tone Cap values......... Well, it is a matter of personal preference, to be sure. But, as Chris has said time and again, both here and abrood, the lower the value of the cap, the more treble you'll hear when the tone control is at 10. This is totally independent of what kind of pickups you have, as well as how many are currently selected, and likewise be they in series or parallel. The cap's value affects the frequency range, it cuts off whatever's above the frequency it can handle. The tone pot itself only controls the strength of that cutting action, it does not change the overall frequency response. That said, a higher value capacitor means that you can never have as much treble in your sound as a lower value cap will give you. For this reason, you often see a 0.02µf (or 0.022µf) capacitor in a guitar - it allows a pretty healthy range of treble to come through. And when you don't want that much, you simply roll back the tone control. Those guitars that have higher value caps can't produce the same high frequencies, no matter what the value of the pot might be..... sad, but true. So the question becomes simple - how much treble to you need to produce? What's your pleasure? You now have the tools needed to determine what value will likely work best for you, but fortunately, you are an Official Guitar Nut - if something doesn't satisfy you, you can change things around until you are happy. ;D HTH sumgai

That's a really neat way of explaining it, Sumgai. Nicely put. The wiring diagrams that came with the 3 SD pickups all refer to 0.047uF caps on the tone pots, but since I have some 0.022's in my box of bits, and I like you, and it is a Tele and meant to be bright i think I'll go for the 022, and if its too brittle then I can swap it out after.

That just about wraps up this project. Wiring works a treat, as per the above (corrected) schematic, particularly the neck and mid pup with the mid out of phase, a really nice powerful jangly rhythm sound and the mini bucker at the neck is warm and thick for some tasty blues. The bridge pup is nasty, loud and biting, just as it should be. Be sorry to see this one go

Well that looks like one fine guitar you are constructing. Good work. My thoughts on the choice of capacitor would be go with the larger value if you can get a "full-on" tone control. On "ten" the tone control has infinite resistance and so it makes no difference how large the capacitor is. Well, I suppose it would make some difference. Let's suppose you used a one farad capacitor. At "ten" the sound would have that bright Fender tone. Turning it to 9 would cause a drastic tone change and some high frequencies may get diminished. ;D
