Greetings - Since I have time to kill I figured I'd start working on the design for project #2. It's an H-S-S with the following pickups: NECK: Seymour Duncan SSL-1 MIDDLE: Rio Grande Halfbreed RW/RP BRIDGE: DiMarzio DP197 Virtual PAF (Bridge) My question is on the proposed wiring for the humbucker. Here's the wiring specs:  | SCREW | POLE | COIL (S) | SLUG | COIL | POLE(N) | | Winding/Polarity | Start | Finish | Polarity | Start | Finish | Polarity | | DiMarzio | Green - | White + | South | Red + | Black - | North |
And here's the sketch:  And here's what I hope it will do: The first switch is just a Series\Parallel switch. This one should work. The second switch is for a combination coil split\humbucker. It's supposed to work like this: UP = Single Coil (N) MID = Humbucker DOWN = Single Coil (S) I hope... If anyone sees a glaring issue with this please feel free to shout it out. Thanks Happy Trails Cynical One |

The problem here is that in parallel mode, the output is shunted directly to ground (through the two wires going to the center terminal of the 3-way switch) so there will be no output in any of the parallel settings.

Ok Buster, here it is.... While you could use Fun With Toggles & Push-Pull Switches take 2 to do this with binary Tree Switching, you can still do it with your switches as well. The trick is to limit things to where they belong. You want parallel, series, one coil, and the other coil. If you make the DPDT switch do the parallel/series thing, and only let the SPDT Center-OFF switch be active in the series mode, things will be fine. If you do this, things will be just peachy as well as fairly keen.  |

If you do this, things will be just peachy as well as fairly keen. Okay, just so I understand this...the DPDT switch stays as wired. As long as the second switch (SPDT - Center OFF, I'll change the SP3T from the drawing) is in the middle position both parallel and series humbucker output is fine...and to continue...ONLY in the series mode on the DPDT switch will the N and S coil split work on the SPDT-Center OFF switch. So, in parallel mode I just have a nifty kill switch... This is fine. I looked at the Fun with Switches posting. I can see where I can get this with one more switch...but having developed CRS I'd like to keep things as simple as possible. Next part is to try and get two volumes and two tone controls...(one each for neck/middle combined and then one each for the bridge) I'll be back with that later...gotta do a little more research... +1 and thanks again for saving my a** on this. I played with this all day and finally took a swag...as you say, thank God it's low voltage... I figure by the time I understand all this I'll have all my projects done... Happy Trails Cynical One |

No, the wiring from the DPDT to the SP3T changed.
No, regardless of the position of the SP3T switch, parallel works fine. In series only, the SP3T selects one coil/both coils in series/the other coil.
Don't change it, I actually prefer SP3T - Center OFF since it has 3 positions/throws, and makes contact only in the two end positions.
Yes.
No, it's neither a kill switch nor particularly nifty.

No, the wiring from the DPDT to the SP3T changed. Yeah, I caught the wiring change between the two switches...and I've made the changes to my drawing Got it. It will remain a SP3T switch. Thank God, I finally got one... ...well, it's sort of nifty... Thanks again for setting me straight. You're the man...but where do you find a phone booth these days to change clothes in?
