    There are other things that can help you identify a pickup.
    Measure its DC resistance, and its inductance.
    Then from a known database of pickups it's easy to find what it might be.

    That is an ARF-master pickup.

    It's a single coil pickup, disguised to look like a hum-bucking pickup.
    No not really but I have seen some like that.

    it's from this guitar ,i thought it might be a super 70 ,but when i tried it i knew it was a much hotter pickup like my dimarzio crunchlab ,so i had to check it out and to my surprise it had no markings at all .that's a 1977 ibanez futura model # 2469 ,guild style headstock .

    A super 70 *is* a much hotter pickup

    That said... the wiring looks odd and messed-with. Is that a separate ground to cover? Why??

    Maybe open it up and see what's inside? A Super 70 would have a huge alnico mag (thick A8, metallic but strong)

    Or measure it's resistance... if it's 7.9-8k ohms but pretty hot signal, it might well be a Super 70

    i have some super 70's and some u3000's photo below ,they have markings .
    i don't want to mess with it because i don't have the know how or the equpment yet .
    but there is a hum increase when i take my hand off the strings . i will ask the tech to take the cover off and maybe measure the unmarked pu and the crunchlab to compare .
    can anyone offer an example of readings on various pu's to get an idea ?
    for example :
    single coil 4 k ohm
    super 70 7-8 k ohm
    crunchlab 11 k ohm
    d activtor-x
    emg 81 active ??? etc etc

    i have no idea why it's wired up like that glad u caught that it's been bugging me ,must be why the hum increases when the volume knob is off and i move my hand away ,it does this on both pu's

    i plan on doing a swap on these 2 guitars 2nd photo

    Singles 5 - 7, Pafs 7 - 8, overwound 8 - 10, super distortion and duncan custom 13 - 14, jb/dd/bw/invader and 500t 15 - 16k

    You can just take a meter to the end of a guitar cable or input jack terminals with all pots wide open to measure a pickup

    Dwhatnow? The meter, you mean?

    20k ohm or 50k ohm or 100k ohm depending on what's on tap

    Basically 20 or more, preferably 100 or less

    ok i got it ,the :
    u3000's = 8
    crunchlab =10-11
    unmarked =8
    my no name white dummy pickups i never use but got for like 10 bucks for show and to fill up the neck space = 14 !
    i don't like the neck rythm position so i always use the bridge and use the toggle to "turn the guitar off ".
    does that mean the white dummies in the neck would give me more distortion and better sound than the 100 dollar dimarzio crunchlab ?

    That all depends . The ohm rating is just how much output the pick ups has . The magnets the type of wire how tight it is wound all make a difference in tone . The More out put The pick has the les the strings will vibrate .

    That's not how it works.

    Else everyone would just run twin Hotrails in series in a humbucker slot and call it a day

    Btw based on the ohms and the distinctive looks of those white "dummies", they're TRYING to be DiMarzio Super Distortion knockoffs... whether or not they got it right though is anyone's guess until you wire em up and/or take em apart and post pics

    guitars are back there's a photo .ok pickups are swapped ,the gold covers have been removed .
    it is not a super 70 ,no markings on the back,but the front does have some T's on them ,anyone know what these are? maybe super distortion knock offs? they measure 8 resistance ,the crunchlab is an 11 ,and the white dummy in the neck 14!.
    ok good news ,is the truss rod works ,the bad news is the frets are very worn and uneven ,he recommends a refret for 330 dollars ,or a redressing for 150 . that sucks ,previous owner or owners really used this guitar alot and or did bends on some strings more than others . he said the neck was a little too back so he turned the truss a quarter ,i don't see really much of a difference . i adjusted the bridge to get real low and still be playable so i guess i can live with it for a while. both guitars feel around the same as action is concerned ,very low .what would u guys do? a refret or a dressing crowning ?
    i asked him what is the most expensive guitar he has ever had there ,he told me a either 100,000.00 or a 400,000.00 dollar les paul ,by appointment for one day .
    since he had 2 guitars of mine there ,i asked him what is the most guitars he has had for one person he goes ,1,2,3,4,5,6,7,8,9, of a rock star's guitars right now , i don't want to drop any names so lets make a name up benny slapwits ,hahaha . i said isn't glowie slapwits his daughter he goes yeah . she's a cute actress .
    i said what are those gold and platinum records on the wall ,he said dokken ,guns and roses ,ratt and great white ,i said they gave u those cuz u worked on thier guitars ? yup .
    well the frx might be here on thursday so ima drop it on there ,try to use it without the clamp . if not i will get some guy to drill a couple holes ,yikes . IMG_2716 (Mobile).jpg

    ok i tried both guitars and my old one is ok ,the one that got the black pickups ,but the new one that got my old white pickups still has some sort of wiring problem. it has too much static ,the guitar guy swapped out the pickups but he didn't fix the problem . what causes too much static or hum in the guitar when all the other guitars and amps are fine ,and the bad guitar has good pickups .

    Usually a bad earth/ground connection.
