I'm about to start work on a dream superstrat project as not only are the stars aligning, but someone just said to me "You can have this big bit of mahogany if you want." As you might know, I'm currently in the middle of rewiring my strat copy as well - the fates are aligning right now so in free moments I've put together a wiring diagram for this second project. It's going to be a two humbucker affair, with the positions:
1. Neck single coil 2. Neck humbucker 3. Both humbuckers in parallel 4. Bridge humbucker 5. Bridge single coil.
There's also going to be a 2P4T switch to change the humbuckers from series wiring to parallel.Now because this is a superstrat-from-scratch, I don't care about throwing ugly toggle switches all over the guitar, as there won't be a 'classic' design to ruin in the first place - when I'm done with it, it ought to look beat up anyway. There's going to be other crazy mods on it as well - solo switches, kill switches, cap switchers, yada yada. But in the meantime, after working out the diagram for the basic five-way switch with either a 2P4T or two DPDTs, I figured I'd be helpful and post the diagram in the completed schematics board. Before I do, can I just have someone proof check it? Not necessarily wire it all up, but look at it and either nod or tear their hair out in frustration. Ta.Click here for the old schematicI've used Greasebucket tone circuits simply because I want to in the project. Obviously if they aren't preferred, they can be changed to regular tone pots.

Ace, You've got some nice potential here. But as you suspected, there are some problems, sorry to say First, your ser/par switches are not gonna work in any fashion, not like you currently have them set up. Second, on your pickup selector switch, you've got one pair of poles backwards from the other pair - when selecting the Bridge pup, you're shorting a coil from the Neck pup. Vice-versa, of course. But almost as bad, you won't get squat in positions 2, 3, or 4 - they're totally unconnected. My suggestion is to take this plan in stages. Go back and completely remove the two ser/par switched from their respective pickups. Ditto for the volume and tone controls. All you should have left is the selector switch and the two pickups. Now, connect the dots to make the pickups work through the switch, as per your chart of desired combos. When that's done to your satisfaction, add the volume and tone controls. Now you're ready for the ser/par switches. I suggest you consult the following topic, it has several possible layouts for you to choose from: Unklmickey's Tutorial on Series and Parallel SwitchingWhen you've digested that, I think you're gonna find that plugging your two ser/par switches is gonna be a snap. But of course, any questions, and you know where to give a shout! ;D HTH sumgai

That's what I thought, too, at first blush. But then I noticed the tiny little lines between the dots on the selector switch, which I took to be jumpers. They're sure easy to miss, particularly for these old eyes.
asmith-
IOW, a little too stylized on the diagram. If lugs are to be jumpered, it's best to show that as a "U" connection so all can see what's going on. Or at least have the lines connect into the dots so it's clear a connection is intended.
This is, of course, a Superswitch or similar, not really the "basic" 5-way.

Of course. Apologies, a slip of the keyboard. I've added hoops to the wires to make it easier to see what's going on. Here you go: As well as that, I've drafted up some rough "flow diagrams" to demonstrate where I see the signal is going in each position. Here's the directory where they're kept. The red lines are indicative of where the South pickups' signals are travelling in completed circuits, and the blues lines are the North pickups' signals. I'm not sure what you mean. I don't see how they'll not work. Could you explain please? Thanks for all the help again.
