Seymour Duncan SVR1N

[newbe]

I have been given a Seymour Duncan SVR1N for the middle and I have ordered a SHR1B for the Bridge, SCR1N for the neck.
The SVR1N is a split rail, half on one and half on the other side.
I was hoping to wire your circuit HHH Strat with parallel/series option for position 2 and 4, modified TBX tone and neck/bridge blend, but not sure how this will work with the SVR1N.
Will I need to change the wiring to suit the SVR1N and if so how do I achieve this or is it an additional switch to be added??.
Alternatively get another SVR1N and fit it next to the other one, but again how to wire them???.
I can follow a circuit but have no idea to create a circuit.

I have previous post about the guitar, its is a one piece strat and am now at the stage to route the pickups and switches.

Any ideas will be most welcome

Are you referring to a particular HHH diagram or scheme?

with parallel/series option for position 2 and 4,

I will assume that, by "positions 2 and 4", we are talking about a 5-way switch? Position 2 being therefore B + M? And Position 4 being M + N?

With those assumptions (if correct), are you saying you want the 2 pickups at positions 2 and 4 to be able to be in either series/parallel with each other? Or are we talking about putting the two coils of each SVR1 in series/parallel?

If it is the first one that you mean, a 4P5T Superswitch will be needed, together with at least one other DPDT switch to swap between "Series mode" and "parallel mode". I assume the pickups in question are all 4-conductor (I didn't check SD's website). If it is the latter you mean, then a regular 5-way switch could be used, together with added switches to do the "intra-pickup" series/parallel (one switch for each pickup you want to switch between series/parallel)

Will I need to change the wiring to suit the SVR1N and if so how do I achieve this or is it an additional switch to be added??.

You will need at least one additional switch, as I said above. You are wanting 7 combinations, and there are only 5 positions on a 5-way switch. The fact that the pickups are the "split rail" configuration won't change any wiring you plan to do. If you were planning to split coils with this pickup, there might be issues because of the half-rail, but you aren't doing any coil splitting.

Alternatively get another SVR1N and fit it next to the other one, but again how to wire them???.

I'm not clear on what this alternative is. You mentioned 3 SVR1 pickups, now you've talking 4? And what is "the other one" that you want to fit it next to- and why?

Sorry for all the questions but I'm trying to clarify what exactly you want to do here.

HHH Strat with parallel/series option for position 2 and 4, modified TBX tone and neck/bridge blend.
this is the circuit wiring I wold like to do.
With the pickups I have, can I just wire to this circuit or do I need to modify the wiring 
I'm not sure about the split rail pickup SVR1N. if it will work without any mods would be fine or just another switch is also ok
All pickups are 4 wire.
As for another pickup, as you say not a good idea, it was just a thought.



"You will need at least one additional switch, as I said above. You are wanting 7 combinations, and there are only 5 positions on a 5-way switch.

Your comment above that I won't change any wiring is ok with me as I would not want to make it more complicated.
Can you tell me how this will work?

See my comments above. You still haven't clarified what you want with that. Wiring in a TBX tone control should not present any problems, it's essentially a separate module from your pickup switching/wiring. The neck/bridge blender may present some issues, not with the pickups, but with your request for series/parallel switching. But it will depend on what you are meaning by the series/parallel switching you want to do.

[newbe]

Its the use of the split rail in the middle position instead of a normal pickup like the other two pickups and I want to keep the series/parallel switching.
I don't know how a split rail pickup works.
Do I just buy a middle pickup like the neck and bridge or will the split rail be ok to use.

This circuit is what I want to use but using the split rail if possible as I have one.
HHH Strat with parallel/series option for position 2 and 4, modified TBX tone and neck/bridge blend, this circuit does not show a split rail in the middle position.

Three times now you have said you want to have series/parallel switching at positions 2 and 4. This statement is unclear.

- Do you mean you want to have the middle pickup's coils switchable between series and parallel? Or bridge or neck coils in series/parallel?

- Or, do you mean that you want to have the bridge and middle (i.e., position 2 on a Strat-type guitar) able to be connected in either series or parallel at that posiiton?

- And, same question for position 4, neck and middle pickups, are we switching these between series and parallel? And, is a single switch going to switch between series/parallel for both positions 2 and 4 simultaneously, or are we talking separate switches for positions 2 and 4?

As I said earlier, so long as you are not planning on splitting the coils of the middle split-rail pickup, I don't see that what you want is impossible or anything, it's doable, but before we can work out a specific scheme here, we need to be clear on exactly what you want.

This circuit is what I want to use but using the split rail if possible as I have one

Is there a particular diagram you are working from? You said you wanted to "keep the seires/parallel" switching at positions 2 and 4. This implies that you already have this on the guitar. How is the guitar wired now? What switching do you have currently?

[newbe]

Its not wired yet and am using a circuit from this forum

HHH Strat with parallel/series option for position 2 and 4, modified TBX tone and neck/bridge blend,

I do not want to split the middle coil, just follow the existing circuit above but using the pickup I was given if possible or I buy another type of pickup for the middle position

OK, please link to the diagram you are using. The middle pickup should not be a problem but let me look at what you are trying to achieve here.

HHH Strat with Series/Parallel Option for Positions 2 & 4, Modified TBX Tone, and Neck/Bridge Blend


Since I like to use my modified TBX Tone Control with humbuckers and I like the look and operation of the Fender S-1 switching pot, I decided to add those 2 things to this HHH Strat with Series/Parallel option setup. That left me with a place for another pot, so I decided to add a Neck/Bridge Blend control.


5-Way Switching:


S-1 Up:
1. Bridge Humbucker with Neck Humbucker Blend
2. Bridge South Coil & Middle North Coil in Series
3. Middle Humbucker
4. Neck South Coil & Middle North Coil in Series
5. Neck Humbucker with Bridge Humbucker Blend

S-1 Down:
1. Bridge Humbucker with Neck Humbucker Blend
2. Bridge South Coil & Middle North Coil in Parallel
3. Middle Humbucker
4. Neck South Coil & Middle North Coil in Parallel
5. Neck Humbucker with Bridge Humbucker Blend

When you are on a page that you wish to link to, simply highlight the url and copy it. Then, when you reply to a post, hitting "reply" brings up a "create Post" window. In this window, you have a series of buttons across the top. One button has an icon of a globe with a page in front of it. Hit that button, it brings up a "Link" text box. Paste the url into that box and yu're done.

S-1 Up:
1. Bridge Humbucker with Neck Humbucker Blend
2. Bridge South Coil & Middle North Coil in Series
3. Middle Humbucker
4. Neck South Coil & Middle North Coil in Series

I thought you weren't going to be splitting coils?? I will definitely need to see the diagram to which you are referring. My concern with your list is that I don't know if you can cut the coils of that middle split rail pickup in the same way as with a regular HB.

If no one can offer a definitive answer, I would assume that if the Green and Black wires from the middle pickup are the - leads of each coil, and the red and white wires are the + leads, I assume for both coils to be active in the SVR1N for each pickup combination you'd need to first connect its coils in series. Then connect its - lead to both places the Green and Black wires from the middle HB in the diagram are connected, and connect the + lead to both places the red and white leads from the middle HB in the diagram are connected too. Otherwise, I wouldn't know where to begin with that switching system.

"From 'https://www.seymourduncan.com/blogs/wp-content/uploads/HumbuckerColorCodes.gif' "
I dont want to get in the middle of this as too much politics for me.
I dont like the colour system, to many and no common, plus being Red/Green Colour blind (why we dont have the wiring colours in Electricals)
Only seem to be using 2 sides of the S1 (might as well have a 2P2T) with the S1 you have a bit more scope to do more if you wanted.
But down to your TASTE of the Person

If what the circuit claims will happen and that is what you want then go for it. As you know with a lot of wiring a lot of possible faults, take time over of (all want to rush and play asap). The colour chart should be the same, the same make i believe uses the same colour coding.

The SD website is not particularly informative about the split-rails pickup and how the "blades" are wired together internally. They don't mention splitting the coils, but it's a 4-wire HB so it certainly can be done. What the middle pickup will sound like when split? You won't know until you try it. I'd say (agreeing with angellahash here) go ahead and wire it up, see if you like it.

If by "split" you mean using just one coil of the SVR1N, I'd assume only the bottom or top three strings would be active.

[newbe]

Thanks for you reply, but its a bit beyond me.
If only 3 of the strings are active how do you get both coils active,  but I will ask for the wiring of a SVR1N. Can you wire the split coils in parallel.

You'd need both coils in series or parallel to have all strings active. It comes wired in parallel. You couldn't have looked here b4 asking?: www.seymourduncan.com/single-product/vintage-rails-strat

That's what my thought was as well. But in looking at the picture of the thing, it looks like maybe the two coils are each split, SO:



If it's the lower one, then no problem splitting the coils. If it's the upper, then gckelloch is right, you'd only get 3 strings.

The bottom and top half of either rail look like plastic bars, so I don't think so. The description says it comes with 4 conductor wires for parallel or series operation. There would be 8 wires if it had 4 coils.

Yeah, they do look like plastic, so maybe you're correct. As far as 8 wires, I was assuming the coils would be internally connected

The description says it comes with 4 wires, but it occurred to me that the pickup would short in the SS position #3. There may be a way to wire it to work, but it's too complicated for me to tell.

Thanks for all your replies 
You have now lost me with this technical problem. 
I have now bought a ordinary sd rail to fit in thr middle  position  and I will return the split rail back to my friend. 
So I'll be following the diagram I posted on the forum.
You guys are the best for help but I didn't understand  a bit of what you were saying. 
As I said before I can follow the circuit but not design a circuit.
Many thanks for all your help, at least I know where to come for help.
The woodwork side of the guitar is the easy bit and for me the most enjoyable part of making the one piece guitar that I have nearly finished.
The guitar will be acoustics and electric and all I have to do is hollow out the body and make a back arched lid.
Again many thanks for all your help

Wise choice to go with another twin rail, but the woodwork side is easy? Those SD rails sound a bit "brittle" to me, but the hollowed body should sweeten the tone. Consider leaving the center line solid at least from the neck pocket to the bridge for better sustain. Mahogany or Alder is always a good choice -- Mahog generally having more bass and less high end. The arched top may not matter as much if the neck is attached to the back piece, but it may have a slight tonal affect. There are enough variables so results are somewhat unpredictable, but a Mahog back with an Alder, Maple or hard Ash top should have a nice balance -- each top wood being progressively brighter. For a good compromise between the electric and acoustic sound, you could start with a ~1'' thick Mahog body hollowed out around the center line, and maybe behind the bridge posts, to the the neck so there's a 4-5mm thick portion left under the hollowed areas. Then hollow out the center of a Les Paul style top in front of the bridge posts to the neck to ~4mm thick. That shouldn't be too hard to do. What do you think?

Oh, right. If that includes the neck I hope it doesn't warp. Ken Parker said the old single-piece Fender Maple necks were notorious for fret sprout back when he was a repair tech. Check out his latest works: kenparkerarchtops.com/guitars2

[newbe]

I did a previous post in the guitar section and the details are in there. the neck and body is made up of various wood and the neck is reinforced with titanium bars. I have used quater sawn wood in oak, maple, mahogany, walnut and ash. It took me a long time to source these woods. The neck also has a truss rod
