Well I never knew that - Fender Lonestar Stratocaster Content

For a while now, I've been planning to replace the PG+ in my 1999/2000 US Fender Lonestar Stratocaster with a Screamin' Demon - easy enough on the face of it. So I got MJ to do me a Demon on white bobbins to keep the look of the original setup, and decided to replace the Kinman AVn69's I put in the neck and middle years ago with a pair of SSL Five-Two's, the middle one being RW/RP. OK, so I've got the pickups sorted, but what about the switching....

I'd always had it in my head that the PG+ was just acting as the full humbucker regardless of the position of the five-way; after all there are no other switches on the guitar, so "why", the thinking ran, "would the PG+ be split at all". So, to get what I was looking for, which was basically being able to run the guitar in position two as if it were a SSS Strat, I've been looking at all sort of options to split the bucker when required and get the quick, or as near as I'm likely to get to it. So ideas of S-1 switches, mini toggles a la Dave Gilmour, or something else were going through my head, or at least they were until this morning.

A it just so happened, I'd cleared another guitar off the bench last night and had put the Lonestar on there anyway, as I'd wanted to check which pots it had on it (250k as suspected it turned out), as I was looking under the scratchplate, I noticed that the red & white wires were connected to a single lug of the 5-way. "That's odd" I thought, but didn't pay any more attention to it until this morning when I saw lex666's thread in the Trading Post where he's selling his Fender American Deluxe Stratocaster. Part way down, I saw a diagram which just so happened to be explaining the switch positions on that axe, which does have an S-1 fitted as standard. And then the penny dropped...

Whilst looking at, I saw that the position 2 selection gave me exactly what I wanted, BUT WITHOUT NEEDING THE S-1 TO BE DEPRESSED. 10 minutes later, I'd located the switch position description for the Lonestar, and low and behold, it does exactly what I want as standard in position 2. All I need do now is wire in my new pickups, the the exact same solder lugs and I should be good as gold. True enough, I can't get the bridge into a single coil only on position one, but I'm not sure I want/need that anyway, and I could always drop in an S-1 later.

The only remaining question is whether the Demon and the RW/RP middle will hum-cancel, as desired, in position two. Time will tell on that one, but that should only be a matter of finding a way to split to the other Demon coil rather than the one that it uses with the default wiring.

With that, I think I'm good.

It just crossed my mind that could solve that by just swapping the positions of the middle and neck, so the RW/RP would be in the neck position, then re-connect the wiring accordingly. Does that sound right?
 
Re: Well I never knew that - Fender Lonestar Stratocaster Content

if they do not hum cancel in position 2, you can swap the leads so the humbucker splits to its other coil. however, since you are replacing a duncan with a duncan, i'd think the stock wiring would hum cancel in position 2, just like it does now with the pg+.

To be honest, that's what I'm expecting. We'll find out a little later...

A Duncan humbucker, split to the stud coil, will be hum-cancelling with an RW/RP middle pup. Thats why, if you're building an HS guitar, you want the neck pickup to be an RW/RP middle pup.
 
Re: Well I never knew that - Fender Lonestar Stratocaster Content

I recommend you check your magnetic polarity before you start to solder. The active humbucker coil when split (normally the stud coil) should be attracted to the mid pickup (if they repel each other they are the same magnetic polarity=no hum canceling). The mid and neck should also attract.

Well the neck and middle attract to each other as you'd expect. The middle attracts to the screw coil though, not the slug (stud?) coil.

Just looking at SD's standard wiring for their humbuckers (see below), it would seem to make sense that I'd get hum-cancelling if the #2 position were to split to the screw/adjustable coil. Whilst the wiring diagram linked to above isn't overly clear, it seems to make sense that the split would be to the screw/adjustable coil, as that's the one that is grounded - doing the reverse seems like a recipe for (more?) hum.

I'll get it all wired up I think and see what happens. It's not like it would take too long to re-work anyway. BTW, I just checked the polarity on original Texas Specials, and they match those of the two SSL52's I have - the educated guess say this will just work as intended.

All Seymour Duncan humbuckers with four-conductor hookup wires incorporate a standard wire color code.

GREEN = start of adjustable/south coil
RED = finish of adjustable/south coil
BLACK = start of stud/north coil
WHITE = finish of stud/north coil

Forget (some of) what I just said. I've just taken a look at the guitar again and what they've done is take the PG+ black lead to ground and the green is being used as the hot. I'll just replace like for like then, and see what happens.

my new dean z, which came with duncans from the factory, is wired the same way. green +, black -.

Well all positions work, least ways they all light up the tuner. I just need to finish the set-up and see what it sounds like now. Job for tomorrow - nearly midnight here.

Perfect, everything should work as planned with hum canceling in neck + mid and screw coil + mid.

My wife has a Lonestar Strat that I get to play with and I'm very happy with the factory (SD) HSS pickups. I didn't realize it had SD pickups until after I replaced the pickups in my Tele and loved the SD tone so much I went after the Lonestar to see what SD pickups I could sneak into it (without my wife noticing hopefully ;) ). That's when I re-discovered it had SDs from the factory. It's a sweet guitar and really too good for my wife ;)

Well that didn't quite work out as expected. Positions 1, 3, 4 & 5 were as expected. Position 2 can only be described as thin and, I'm guessing, out of phase.

Looking back through the Fender diagram and also at the Seymour Duncan ones (both reproduced below), is that neither show how the PG+ was actually wired up when I got the guitar, also bearing in mind I got it new. Both the diagrams below show the black lead attached to the switch, with green to ground, which is the opposite of how the guitar was (the PG+ wiring has never been touched btw). Time to open her up again and go through everything joint by joint, wire by wire... :scratchch

A Duncan humbucker, split to the stud coil, will be hum-cancelling with an RW/RP middle pup. Thats why, if you're building an HS guitar, you want the neck pickup to be an RW/RP middle pup.

This is only true if the RWRP middle is also a Duncan pickup.

Fender single coils (e.g. the Texas Specials in the Lonestar) are wound with opposite polarity and wind direction as a Duncan single coil. In other words, a Fender RWRP is equivalent to a Duncan standard wind, and vice versa.

If you have a Duncan humbucker and a Fender middle single coil, you need to wire the humbucker in reverse (green hot, black ground) in order for it to hum cancel when split.
 
Re: Well I never knew that - Fender Lonestar Stratocaster Content

No, they will be all SD. 1x Screamin' Demon, 1x SSL52 RW/RP and 1x SSL52 std

You may have given me a clue though. As it did originally have the Texas Specials in it, I should perhaps switch the black & green around on the Demon.

One way or other, some combination of wiring swaps and possible flipped magnet should get me there. Step by step though...

If everything is Duncan, you're good to wire up the humbucker the standard way (black hot, green ground). If you follow the SD diagram you posted above, it should work exactly as advertised.
 
Re: Well I never knew that - Fender Lonestar Stratocaster Content

All sorted. Green to ground, black to switch and everything is as it should be. Just a pickup height adjustment or two to go and all will be right with the world again...

Thanks for all the help... :)
