    Awrite, fellow SG-slingers!

    I've been shopping some humbuckers, for resale. The seller said these were from the same guitar, an 1980 LP Custom. This a set of two uncovered humbuckers. I havent tried them in a guitar, but they both read round 3.8, so I wonder if something's wrong with these. (The seller didnt know, he just knew the pu's originated from a -80 LP Custom and had never used these pu's. The guy is in a band, seems like a cool guy, and has confirmed he didn't know about the low DC-resistance readings.)

    Now. First I sure would appreciate a bit of help on identifying these pu's. I have now learned that around 1979/1980 Gibson started to replace the T-tops (the ones that had been unchanged since -75, after what I've read) with the Tim Shaw-developed humbucker. I've researched heavily on the net, talked to guitarpeople, pros and amateurs, and to me it seems like the pair I bought could be a pair of so-called "Transitional Shaws".

    But I am by no means certain of this, and luckily I got ETSG! :D Yeah!

    This is the humbucker I think was in the bridge on that 1980 LP Custom. This has a "T" on the bobbins, but its not a 2-conductor pick-up ...

    This is no T-Top is it? To me this humbucker looks like a modded T-top or a so-called "T-Shaw".

    Here it is:

    And here is the other pickup, I believe was in the neck position on that LPC. I think this is a early prototype Tim Shaw from 1979 or 1980, but I'm not 100% certain. There is a smeared-out stamp on it, very hard to see, but I believe you can see it on some of the pics. I think its that XXX-XXX code with numbers.

    But what do YOU say, ETSG?

    What does the ever-impressing expert panel on the worlds coolest forum say?

    (The limit of ten pics is reached, the thread continues in a moment ...)

    Interesting riddle! The DC readings are about exactly half of what they "should" be. Maybe due to broken wires resulting in only one bobbin being read by the meter? I've never heard of any Gibson humbuckers with readings like that. I suggest you wire them up to something and test for sound.

    Yeah, interesting, for sure, mister! That's the reaction I hoped for! :D I do believe The Incredibly Laid Back And Extremely Resourceful Superpanel of SG-Experts here on ETSG will accept this challenge. :D

    And yeah, never heard of such low outputs me neither. And I'd like to try them out, but, well, yeah, I need a guitar for that ... And since I dont wanna touch anything on the electronics on my trusted and extremely sentimental-heavy 1995 Epiphone G-400, I guess my newly aquired 2000 Standard gotta be try-out guitar. I think I will do a shootout, just using the phonecamera, to compare this set of (hopefully) hybrid-Shaws to my new 1977 T-Top (bridge position) and the 57 Classics set I'm installing on the 2000 Standard these days. (Picked up a set of new 500K pots the other day :))

    Regarding trying these weirdos out, I just want to check if I can do something with these first, you know, maybe see if I can do something about those low DC-resistance readings.

    Edit: Regarding a try-out guitar: Doing anything with my 2018 Standard - The Autumn Beast - is most def ruled out, that guitar just plays and sounds just over-the-top good now :D

    (Hm. A pic of that guitar is never wrong IMO :D Here's my No. 1:

    Gotta say I've been looking forward to posting this thread! Venter spent nå. :)

    Alltid fett med nye pickups!

    If the wire’s broken somewhere, Wouldn’t a rewind be the best option?

    If you don’t get any more helpful answers than mine here, I suggest sending an email to Gibson themselves, to check if they know of any such pickups being used at that time.

    Yeah, I'm sure you're right on that rewind-solution, if its the wire. I wonder if that's way-off expensive or if it could be worth it ..?

    And mailing Gibson might help, too, but I honestly doubt they can help with the ID-part ... To me it seems like Gibson is not sure themselves of what they had or did at times ... Around 1979/80 they seemed to be in a hurry installing pu's on some models, but what do I know ..?

    Sidenote: I did have a black 1980 LPC myself once, got it in 1995 I think, sold it a year later (it ATE strings so I decided it wasnt a keeper), but then again, I didnt really give a damn about pu's back then, and through my JCM 800 that LPC sounded just fine with me, and that was it, hehe.

    Intriguing. From what I can gather on the net, your pickups might very well be "transitional" tim Shaw pups (or one T-Top and one Shaw), but the DC readings and the non-braided wire on the T-Top are puzzling. But what are the chances you have bought not only one but two defective pickups at the same time?

    Yeah, me too, very intriguing stuff these models.
    And yeah, whats up with the wires on that quasi-T-top ..?

    Chances me buying defunct pu's are big. And I can only blame myself if that would prove to be the case here. I guess the worst scenario is a case of misspent money and a lot of freshly aquired knowledge about Gibson humbuckers from the period 1967 to 1986-ish:D

    Got these mysterious humbuckers pretty cheap, approx. the same price as you pay for one T-top on Ebay, so it could be worse. Hopefully a collector is interested. I dont think I will lose all my moneys ...

    But this is exciting stuff!

    Someone’s been inside that “bridge “ pickup


    Gibson hasn’t ever used that kind of hookup wire. If you’re lucky one coil was disconnected because the player wanted a single coil sound.

    But I wouldn’t count on it.

    Plan on the worst case scenario Rewind. Which isn’t so bad.

    Thanks. I have been suspecting just that, about that quasi-"T-top". It does look pretty modified. Gotta find a guy in Oslo that rewinds for a ok price.
    Thanks.

    Anyone have a clue about the Tim Shaw? It looks original to me. But I guess it will sound below-low-output with those readings?
