HSS Schematic help question

[tone]

Hey guys. In this HSS schematic, is position #4 middle single coil + one coil from the humbucker, or middle single + whole humbucker? Also, is position number #2 neck/middle? With this diagram, can the middle tone knob be used on the middle, as well as humbucker? If not, can I just move the tone knob wire from the middle sc lug, up to where the humbucker lug?

As you can tell i'm not very good with schematics. I'm building a HSS strat, and looking for a schematic for this wiring:

1-neck
2-neck/middle/ hum-cancelling
3-middle
4-middle/one coil from split humbucker/ hum-cancelling
5-humbucker

I wanted one master volume and two tones. One tone for the neck, and one for the bridge humbucker, unless there is a way to make it work with both the middle and bridge pickups?

If I have a tone knob on the neck pickup, does that mean it will work in the neck/middle position? And also same for the bridge. If I'm using one on the humbucker, does that mean it will work with it's in between position?

Also, i suspect I need a RW/RP single coil. Does it go in the middle, or neck position? I've seen people suggest both, so I'm not sure where to put it. The pickups used will be an EVH, and two APS-1 or 2's. Not sure which to use on a 10"-16" compound radius fretboard.

Thanks!:amish: :smokin:

Re: HSS Schematic help question

position 4 is neck split/ middle #2 is bridge/ middle im pretty sure.

Re: HSS Schematic help question

also, if you take the one wire that goes from the tone knob closest to the output to the switch and solder that instead of on the one lug with the middle pickup to the one with the bridge picup, you will have it work for the humbucker.

I think people call it both ways, but the schematic is showing position #4 as bridge/middle I think.

Re: HSS Schematic help question

Got one more question.

I have an EVH '78 4 conductor humbucker. With that schematic linked at top, what coil would be used in the split #4 position? Slug, or screw coil? I've read that the closer coil get's a more stratty quacky sound in #4 position.

Re: HSS Schematic help question

The humbucker is split in position 4. If you look at the schematic you can see that the bridging wires (red and white) are going to the opposite side of the switch which is being used to ground the one coil. If all the p/ups are Seymours and the middle is RW/RP then you will have noise cancellation in positions 2 and 4.

If the pickups are from different manufacturers you won't be able to rely on the schematics, you'll have to map the polarity of the p/ups yourself. I posted a how-to on here last week I think but the board moves so fast I'm not sure where it is now.

Seek and ye shall find, my son. Start with "find all posts by OctaveDoctor" let me know if you find anything worth reading....

Re: HSS Schematic help question

Hey thanks for the info!
Yeah all pickups will be seymours, with the RW/RP in the middle single coil.

With this schematic, what coil of the humbucker will be use in position #4 with the middle single coil?

Thanks!

Re: HSS Schematic help question

Hopefully Doc will forgive me, but using that diagram, you need a "normal" S-D single coil in the middle and the RW/RP in the neck. Wired as shown, the humbucker is split so only the slug coil is on and it is effectively RW/RP.

I'm virtually positive that the info on S-D pickups from this StewMac info is accurate.

A normal S-D single coil is south polarity and wound clockwise (except Antiquities and some Tele pups...). The slug coil of an S-D humbucker is north polarity. If you wire up an S-D humbucker like they show, the slug coil is effectively wound counter-clockwise (start & finish are flipped). So, if you want the split-bridge/middle combo to be humcancelling, you actually need a "normal" S-D single coil in the middle (and a RW/RP in the neck for humcancelling with neck/middle).

I hope this helps.

Re: HSS Schematic help question

Thanks for the info!
Assuming I take the middle pickup tone control wire and move it over to work with the bridge humbucker instead, does this schematic look like it's the right one for what I want?

1-neck
2-neck/middle/ hum-cancelling
3-middle
4-middle/slug coil from split humbucker/ hum-cancelling
5-humbucker

Re: HSS Schematic help question

Yes.

Neck - RW/RP

Middle - "normal"

bridge - 4-conductor humbucker

Re: HSS Schematic help question

Thanks Fresh Start!
Since I got two answers in here for which spot the RW/RP should be in, I emailed seymour duncan support. I got two answers there too. Can anyone give me a definite answer on which spot It really needs to be in for the switching that I want, with that schematic? No disrespect to those who have voiced their opinion on where it needs to be, I just want to be sure.


Here's the schematic:

And here's the switching I want, and I will change the middle tone pot to work with the bridge humbucker instead.

1-neck
2-neck/middle/ hum-cancelling
3-middle
4-middle/slug coil from split humbucker/ hum-cancelling
5-humbucker

Thanks!:usa1:

Hi Tone -

OctaveDoctor is a professional luthier, and I respect his knowledge a great deal.

Before my last post, I called Seymour-Duncan tech support and talked with Scott Miller to confirm that wired according to that diagram, the slug coil will be humcancelling with a "normal" S-D pup in the middle. (I also sent Scott a link to this thread and asked him to contact me immediately if I'd gotten anything wrong.)

We all understand your concern - it bites to wire up your guitar after lots of research, only to find that some assumption is wrong (or you confused two black wires 'coz you were soldering late at night).

Please call S-D if you're still unsure. However, I am as sure as I can be that what I wrote earlier is correct based on my own fat-strat and talking with Scott.

Chip

P.S. Just to confuse things a bit, some people (myself included) think that you get a sound more like a single coil strat if you split to the screw coil and use a RW/RP single coil in the middle. I think this is because the screw coil is a little weaker in output and the humbucker coil closer to the bridge is also closer to the position of a bridge single coil in a Strat.

If you want to try this alternative approach, use your diagram except do the following for the humbucker:

wire white & bare to ground
connect black & green on the "right" side of the switch
use red as the "hot" lead from the pup (instead of black), connecting to the "left" side of the switch.

Please forgive me for introducing this complication - you can get the same result by using a normal single coil in the middle, wiring just like the diagram, and rotating the humbucker 180 degrees so the slug coil is closer to the bridge. That's what I did for more than a year. Only problem is that the logo on the pickup was "upside down", and people kept telling me the pickup was installed wrong.

Re: HSS Schematic help question

I always get two answers on this also, from duncan as well.

Re: HSS Schematic help question

I also need to point out that the "rules" for S-D pickups seem to apply to humbuckers and Strat single coils only.

IIRC Antiquities are "backwards" and Tele single coil pup are inconsistent.

Fresh Start,
Thanks a lot for the help! I did'nt know you contacted SD too! Thanks! Yeah I wanted to try the slug coil of the humbucker combined with the middle single to be humcancelling in #4. I heard the slug coil gives a nice sound, but maybe later I'll try the other coil like you suggested too.

Okay so middle is normal, and neck needs to be RW/RP huh? All systems go.
