We've had some discussion in the past about the SD TripleShot™ Humbucker Ring. For those who may want to explore the wiring possibilities of this piece, here's the skinny on the switch logic:    These are interesting, I think, primarily because one could add quite a few options without having to drill holes in your '59 Goldtop. The switches may be a bit too tiny for quick switching onstage, more of a "set it and forget it" deal. But I haven't played with one yet so that's just speculation, maybe it wouldn't be a big issue. Is there more to be had here than just the series/parallel/SCN/SCS options described above? What about a HB sized P90, could you do OOP on one switch and a "cap bleed" setup on the other? Or a 4-wire HB with one coil "half out of phase"? All members are hereby challenged to post alternate schemes for this Ring Thing.  |

neweyThat's an interesting bunch of graphics that were posted but I don't think it explains things enough. Copying (and editing) the upper right section of the bottom diagram, I drew this.  Notice that the top row of switch terminals (those 6 circles) do not enter into the Triple Shot circuit at all. So, what we have is a circuit consisting of 2 SPDT switches. (binary tree switching?) The terminal marked R is the only place where the red pickup wire makes a connection and the same applies to the white pickup wire and the terminal marked W. The black pickup wire is always connected to + and the green pickup wire is always connected to ground. Now that we have cleared that up, I drew a neater single-pole diagram of the circuit.  Note that when Coil B is active, the + lead of coil A is "hanging from the hot" connection. I thought SD Triple shots used DPDT switches to prevent that. Now I guess they use these because they are more secure mechanically?

Wolf-
Look again. Although they are used in a SPDT configuration, they are, in fact, DPDT switches. Notice the blue lines denoting the switch logic, and showing the connections made on the other pole of the switch.
One could (carefully) solder to the 6 unused lugs, I would think, and thus get some other combinations. For starters, one could eliminate the hanging from hot "issue" (assuming that really is an "issue").

OK, I don't know if this is doable or not. It would mean soldering the hot pickup lead to the board instead of the wiring pad, and requires a couple of jumpers (Green and Orange as shown) across the board. And I'm not happy about the 2 "off" positions. I was trying to get one of the Offs to be "on" through a cap, but I couldn't seem to work that out, and I'm not sure if you have room to add a cap in there anyways.  But this should get the discussion started!  EDIT: The above did not involve cutting any traces on the board. If one could cut the connection between the 2 poles on the left-hand switch, other possibilities are opened up. Then, the left-hand switch could be wired as a standard phase switch, and the right-hand switch becomes just an on/off switch. Much more logical switching that way, it would seem. Cutting the trace on the Black (Hot) side of the Board could enable even further possibilities, subject to one's ability to wire the thing and still keep it all stowed under the ring. |

Interesting newey
I'll agree with you that the connections across both poles of the switches can present quite a problem.
Trying to eliminate the one on the black wire seems very difficult. I think you'd have to cut the circuit board trace and then solder a new wire to the bottom right terminal. You bring up a good point about the feasibility of adding new wires to the switch terminals and still be able to squeeze everything under the pickup ring, especially if you are trying to include a capacitor.

 How about a Broadbucking style cap between the pickups It could be just a straight cap to ground or wire it to the back end of the tone pot. JohnH has a good example on his Strat SP diagram. You could also use it to control two pups, like a P90/tele and toss/use the blade switch for something else. Or with a three pickup guitar to control the N/M or M/B pups. These Triple Shots can really cut down on the p/p pots we all try to cram into our guitars |

what i've been wondering about these things is if you could put 2 single coils in them. Frinstance, for the neck postition, I'd like to put my fender texas special and a SD Vintage Rails that i have extra. Just to be able to switch betwixt and between would be cool enough, but then to run em parralelly and serially together, that would be wicked nutz.

Thats what I'm in the middle of doing, making my own P-rail, if you will, looking for a P90 style pup for my SD Vintage Rhythm/Broadcaster set One pup is wired to the black/white pads, and red/green for the other so the two combos are n>m or m>n neck to blk/wht and mid to red/grn is m>n mid to blk/wht and neck to red/grn is n>m Problem I had with the TS was you had to switch away to select that coil. See it as m>n Reverse the order (n>m) and you logically switch towards the pup Think I've seen some ppl cut them up and put them on 3 sc strats... |

I would guess that the space inside the SD Triple Shot™ mounting ring is precisely the same size as any other humbucker pickup mounting ring. I would think this is not enough room for two single coils.

But to answer you question, maybe a strat size coupled with a tele pup? two tele pups? |

I'd say the easiest thing to do would be to get a humbucker mounting ring and seeing if two single coils can be squeezed in.

Or, just google the dimensions . . .
A Strat SC is bigger than the Tele neck SC, so I'll use the smaller Tele p/u as an example.
For a std Tele neck pickup, the coils are slightly shorter (65.15mm, incl cover) than a std HB ring (68.4mm). The width, however, is 19.93 mm because of the triangular base plate. 2 Tele coils next to each other are therefore 39.87mm, and the HB ring is only 36.52mm wide.
Now, the base plates might be able to be modified so as to fit, but it might not sound like the pickup you started with as a result.
With a Strat pickup, the baseplate is even wider, about 23mm, so the problem only gets worse.

 newey, It seems that the dimensions I found on the Internet are slightly larger than what you found, but it's a small difference. |

You might get away with it with the Kent Armstrong rails as they don't have the flange a normal single coil does at the base.  That's the closed cool rail. I've got one for project #1, so I'll dig it out tomorrow and see what it measures out to be. Either way, a standard humbucker ring is not going to work anyway, as there's only one hole for the pickup height. You're probably moving into the DIY section to make it work properly. HTC1 |

Yeah, I was assuming you'd have to drill extra holes. But wait, there's switches where you'd need to drill!  Of course, you could use a single SC:  |

Good point neweyI guess this graphic shows that even a single coil would require eliminating one switch.  |

Suggestion: Can you fit two single coils in a humbucker casing and pot it w/ wax?
Ended up getting a TV Jones TV'tron for the neck pup
so the TS can control the neck and middle pickup

OK, so here's a twist on the original challenge: how about "allowing" any switch on a TripleShot be applied to any coil(s) on the guitar. In other words, let the switches act on coils that aren't inside the same mounting ring.
What strange and/or interesting combos can we dig up?
Standardizing the language: a "normal" TripleShot installation in a six-coil guitar with three humbuckers could have three TripleShot rings, with the pair of switches on each ring acting on the pair of coils inside that same ring. Let me name the coils and switches, for ease of reference: coil#1 is nearest the bridge (through to #6, near the neck); switch#1 is likewise nearest the bridge; TripleShots are TS#1 to TS#3. What if I soldered the red/grn leads from coil#2 onto the pads for TS#2 (and from coil#3 to TS#1)? And so on.
On a HSH guitar? Or even HSS!
And what if I were very interested on phase switching some coils? Might have to sacrifice other configurations, like series/parallel, but what could I gain?
Thanks from a newcomer.
