Question about Original Early Patent Number Pickups

Hey everyone. It's been a long time since I've been on this site, but it's nice to be back. I'm looking for some information on the Patent Number pickups and figured this would definitely be the place to get the best info.

What I'm specifically interested in is what year approximately the different changes happened, how the changes effected the sound, and what the current going rates are for the different versions.

I'd like to know the following:
1. When the coil wire changed from the purple enamel coated wire to the orange poly coated wire.
2. When they changed from two black leads to one black lead and one white lead.
3. When they changed from a random number of turns to a more uniform number of turns on the bobbin wire.
3. When the bobbins changed to the T-Top style. I've heard some say this happened in late 65, and others say no, it was later, closer to 67. Not sure which is accurate.
3. What is the perceived difference in sound between the purple wire PAF/Patent Number and the later orange wire version (Pre-T).
4. What is a fair price for a purple wire patent number and also for the orange wire version (Pre-T of course). Also to be clear I would not expect covers to be included.

The reason I'm asking for this info is I have this old battle axe LP/SG from 1961 I would really love to drop an original set of purple wire Patent Numbers in, but I want to really understand the changes from year to year and the current market pricing before I make any purchases.

Back story on the guitar: I've had it since 2011, and it's been posted on this site a few times but many years ago. The bad news is she suffered a neck break and a headstock break well before I got her, however the repairs are very solid and she feels, plays, and sounds great with an amazing natural resonance. As a result of the breaks/repairs someone pulled the original PAF's, and tuners, and the ABR bridge is slightly later as it is the retainer wire version from somewhere between 63 to early 65 in nickel not chrome, but with metal saddles not the nylon that was most common in those years. It also appears at some point the sidepull trem was removed and a long tail Bigsby was installed, then the original sidepull was later re-installed. The good news is the original harness is still intact with pots that date to either late 1960 or early 1961 (it's been years since I inspected that and I can't remember specifics from that long ago, just that they were all either late 60 or very early 61), and all of the plastic parts are original. She also just happens to have some really cool mojo that one of those new fangled Murphy Lab Heavy Aged guitars would kill to emulate, but could never hold a candle too. She was definitely someone's main gigging guitar for decades and was as they say "rode hard and put away wet". I just wish she could tell me her story. The guitar actually had no pickups at all when I purchased her, and now she has a set of Duncan Antiquities.

To be clear, I also fully understand putting early Patent Number pickups in it is never going to restore the value of the guitar, and that is not my reason for wanting them. Frankly that's a moot point as I never intend to part with her. She just sounds and feels too good in the hand, and I feel like she deserves a proper pair of pickups. I really want the purple wire version as I'm fearful the orange wire version is going to sound more like a T-Top than a PAF, and I would love it if they sounded like the PAF's that are in my 62 Ebony Block which sound amazing. The Patent Numbers in my 64 spec early 65 also sound great, but the 62 PAF's just sound a tiny little bit better. As the covers have never been off on the early 65's pickups, I'm not really sure if they are still the purple wire or the orange wire, which is also a reason for my questions above.

Any help with info on the early Patent Number pickups would be highly appreciated. Thanks in advance!

And now for some pron: Here is the 1961 LP/SG


And here she is with her sisters, my minty 1962 LP/SG Ebony Block and very early 1965 (all 64 spec)


And a pic of my mid/late 65 for good measure

That’s an excellent trio of SGs!

Here’s some info on early PAT# Gibson pickups: (scroll down)
PAF and PAT pickup info

My opinion: There is no sonic difference between the last version of the PAF and the earliest PAT pickups. None.

I don’t have enough experience to comment on later PAT pickups.

Another opinion: Avoid the chrome and stick with nickel.

One last opinion: The narrow spaced “jazz/Byrdland” version of a nickel PAF/PAT pickup will sound identical to a standard spaced version. It might look a bit off - but only if you really, really stare at it - but there will be no sonic difference. The problem is to find a narrow spaced nickel PAT. They’re not as common as the gold. You could always go gold and keep the covers off. With the covers off, the look will be indistinguishable from standard spacing, with the exception of whatever gold, if any, remains on the pole pieces.

From my experience I cannot detect a difference sonically in Orange poly wire vs Purple Enamel ( it's simply a coating). I insist on Poly on my Jimmy Page Neck pickup I make because it's easier to work with. It sounds accurate because of the MAGNET..Conversly, A boutique Replica PAF with period correct plain enamel won't get the "target" sound unless it had the correct magnet. Enamel or Poly does not have a sound imo . Hear the Poly Page neck pickup comparison Original vs Mine at 06:14

Thanks for the responses everyone. Although I really need two, I found one within driving distance from me and it includes the nickel cover for what seems like a decent price. I know there are fakes out there though and wondering if anyone can tell me if this one looks legit.


Thanks!

One black and one white wires began in '65.

I'm another that has the last PAF being virtually the same pickup as the pre-T pat number pickups. The uniform 7.6-ish winding started with the short magnets in late '60-61 so they're all about the same. T-Tops sound about the same (I've never noticed a difference).

I've got an early Pat # in the neck of my 59 replica (7.6k), and a 61 PAF (8.6k) in the bridge. Both have the same round/square hole feature, and they both sound killer. IMO, early pat # and later pafs sound the same.

Something's fishy here. It looks like someone messed with the coils on this one. The window holes should be a mirror image to one another.
Amateur re-wind, perhaps?

Good catch!
Though I can’t ever remember seeing this before, I wonder if it could have come from the factory this way?

I saw this once before about a year ago. James Finnerty, who wrote the book on PAF's, says it's not a factory error. See my exact question in the other forum. I passed on the set in question, as a result. ;)

Hi - here are a few of the answers, just from my own experience.

You will find a lot of info out there that disagrees with my responses here, and my answers sometimes get a decent amount of criticism when I tell people, but I’m confident that this is as correct as you will find.

My answers here relate specifically to nickel and chrome covered humbuckers (since gold covered are always a slightly different timeline):

1. When the coil wire changed from the purple enamel coated wire to the orange poly coated wire.

Late 1965 is my estimate for the humbucker change from plain enamel to orange poly wire. You will find plain enamel wire on Gibsons that shipped well into 1965 - I am talking about through Summer 1965, at least. Believe it or not, I think it is even possible plain enamel continued into around early Fall 1965 or so (actual guitar shipping dates). The plain enamel continued into the early chrome cover time period, so in 1965, you will find plain enamel wire well into mid-1965, even AFTER the changeover to chrome covers.

To further complicate matters, there was also a window of time for some portion of 1967 when plain enamel wire was used once again (after orange poly had been used solidly through 1966 and into 1967, just previously). For these 1967 plain enamel humbucker examples, they have one white and one black lead. When seen “in the wild” today, and when separated from their original guitars, these examples (combination of plain enamel, with one white and one black lead) are often erroneously identified as “transitional” “circa 1964” pickups, when in reality, they shipped at some point in 1967.

2. When they changed from two black leads to one black lead and one white lead.

Same answer as above for question #1. The double black leads continued into Summer 1965, at least, before the change to one white and one black lead.

3. When the bobbins changed to the T-Top style. I've heard some say this happened in late 65, and others say no, it was later, closer to 67. Not sure which is accurate.

Late 1967, at earliest, and possibly even as late as early 1968 is my personal estimate, for the start of T-Top bobbins. Much, much later than most guitar references will tell you. You’ll find exclusively pre-T bobbins well into late 1967 (at least).

4. What is a fair price for a purple wire patent number and also for the orange wire version (Pre-T of course). Also to be clear I would not expect covers to be included.

For a purple (plain enamel) patent numbers, currently, for an original pickup in excellent condition, I’d estimate around $2,250 to $2,500 without the cover. With the original nickel cover, closer to around $3,000 (since a set of original nickel covers often sells for over $1,000 these days). You might find extreme examples selling below, or even above, this, but this seems to be the current approximate ballpark range.
