Okay... Just got done painting and drilling on my triple pup LP (All 3 are 4 wire)... I'm trying to run individual micro toggles for coil cut (6 of 'em right below the coils.), 3 volumes, one tone, and a series/parallel DPDT (2 way on/on) Got rid of the pickup selector, because it's extraneous with the individual cut switches, and I put the series/parallel in it's place. I'm wanting to run the series/parallel however possible, even if it's neck/ center and bridge...
I've been all over the internet and my local shops, and all I keep hearing is, "Try the Super 7!" But it's not to my personal taste... All I know for sure is that without help, this wiring newbie will NEVER get it right...
Can anybody please help with a wiring diagram, or reasons why this can't be done? I'm trying to quit smoking, but this isn't helping... A guy in another forum told me to try here.

ohdub, Hi, and to the NutzHouse! Tell that guy in the other forum thanks for the kind word. No one here is gonna tell you that it can't be done. Indeed, this kind of thing goes on all the time..... albeit usually in a Strat-styled body, but nevertheless....... Just to clarify things: Have you already purchased the switches and other stuff (or do you have 'em in your junk bin)? Do have certain combinations in mind that you really want? Depending on your answers, we may already have a diagram stashed away on these pages, or we may have to break out the CAD machine and exercise several brain cells. Either way, you should be happy within a short while (unless your meds are expired.....) HTH sumgai

oddware-
Welcome seconded!
sg's question about whether you have already got the switches in hand is pertinent. Bear in mind that, soundwise, the ability to select either coil of a HB may not make much difference in the mid and neck positions. And a single 3-way switch (DPDT on-on-on) can be set up to give on/off/SC.
So, theoretically, all of the sounds would essentially be available with only one switch per pickup, or perhaps 4 total with 2 at the bridge, where it may make a difference tonally.
Also bear in mind that, with 3 pickups, 3 SCs at once can only be partially hum-cancelling, so the ability to choose which coil is split doesn't really help with hum-cancelling.
Things could thus be simplified substantially, while still giving you all the essential sounds.
Now, of course, if in your heart you really want 6 switches, no one here is going to tell you you're Nutz. We all are!

Welcome to the Nutzone. Please, don't feed the electrical engineers. So I presume you're pretty much set on having six switches! Series/parallel with just a DPDT is going to be difficult. If you've got more than two pickups on, and you want to switch them all between series and parallel, you've only ever got two poles to play with. Since you're sticking it in the place of the pickup selector, I'm going to assume you've got a toggle at work there. In that case, if you wanted to do it exactly as you've already planned, as far as I can see, you'll probably need a 10PDT toggle switch instead. Ouch! I hope there is a simpler way to do this too. But if there's room for a 10PDT, you can wire your individual coils to 'on/bypass' instead of 'on/grounded,' and wire up your 10PDT switch to put all the selected coils in parallel with each other or in series. To illustrate. Let's number your pickups (1) to (6), from the outermost Bridge coil to the outermost Neck coil. Lets assume that (1) is always grounded. So straight off you need a pole to put (1) in parallel or series. Then another pole for the negative output of (2) and another for the positive pole. Another two poles for the negative and positive outputs of (3), and so on, until you only need one pole at (6), to determine where the negative output's going. Ten whole poles. So, Newey and SG are probably right on this one. It's easily wire-able to have a DPDT on-off-on toggle switch - one that could fit in your already-drilled holes - that selects between humbucker in parallel/single coil/humbucker in series. It might be more pertinent to use six of these instead, with some nutty wiring that treats (1) and (2) as a humbucker, (2) and (3) as a humbucker, so on and so on. EDIT: I've tried a diagram of this and it doesn't work.I'll think of that and whether it might work some other time soon. We are but mere mortals here. EDIT: No, that doesn't work. If you toggle something off in parallel mode it shorts everything to ground.

Welcome oddware I was curious - what exactly is the Super 7?

asmith - 10pdt! - yes I agree! That is what you would need to take 6 coils and put them all into parallel or series. If you did, you can then control them with a dpdt for each. Its an example of the general result that you need a switch with 2n-2 poles. So for series/parallel on two coils/pickups, you need 2x2-2 = 2 poles (a bog-standard design). With three coils you need 2x3-2 = 4 poles (we have several schemes for that, using 4pdt toggles) etc
oddware - based on the holes you have comitted to, I suggest your best result is as follows (and its a good option too):
instead of switching each coil, use your two dpdt's per pckup, one to switch the pickup on andoff, and the other to switch from series to single coil, or series to parallel (pick one option). Or, get new dpdt on/on/on switches and you can have series/single/parallel on each pickup.
So that would get you down to three pickups and use a 4pole toggle to switch them all into series or parallel. In amongst all that, you can have your individual volume controls per pickup, and a master tone at the end (not an ideal place for it, but probably the best option here)
All of the above can be derived from designs that we already have on GN2, so it will definitely work.
References for the series/single/parallel switching of one pickup are many. For the series/parellel wiring of three pickups, Wolf has a clear diagram on his site, and in another post Ill link to some earlier ones here (Mr Wolf - could you provide a link please?)
If you like the sound of that, then a wiring diagram will be needed - which Im hoping somebody else will volunteer to do. It will be a doozy, because the 4 pole toggle has 12 connections and it is in the upper bout, remote from the other controls. A multicore cable will be needed to connect to it.
cheers
John

It's hard to picture quite how this would work on the guitar...and others have had concerns if it can work at all...personally I'd be a little concerned about switches being located so close to the coils and libel to be hit with the playing hand. It must have taken a lot of routing to get switches like this in an LP... If the guitar is already drilled out, perhaps it's too late for this option...or perhaps it could be worked in some how... the "free way switch"... It woks like a "gear shifter" with 6 positions... www.stewmac.com/shop/Electronics,_pickups/Components:_Switches_and_knobs/Free-Way_Pickup_Switch.html

Thanks John HTo see a switch that is wired for series/parallel switching for 3 pickups, go to this link: www.1728.com/guitar2a.htmand scroll down to the middle two graphics. The specific wiring you need is the way the 4PDT switch is wired.
