About 2 years ago I compiled a list of DC-resistance values and magnet-types to help me identify the pickups currently in use with Gibson/Epiphone(w/1 or 2 exceptions), this after someone tried to sell me a couple of fake Burstbuckers. Thought this might be usefull to some of you.

Gibson's Pickup Guide, does not show DC-resistance values, and merely indicates (relative) output.
The following values are for the most part actual measurements and not the manufacturer's paper-specs.
Please read the accompanying notes and use this list at your own discretion.

I don't do "Vintage". For vintage pickup identification please consult the resident experts on the appropriate forums.

Magnet-type is usefull in visually identifying a pickup. All Al-Ni-Co-types are a metal composite and look the part... Ceramics are resembling dark-grey/black bars of plastic or clay.

KΩ-values are measured extremes in KΩ(Kilo Ohms). Values may fluctuate depending on the coilwind, meter and human accuracy, resistive elements in the circuit, and temperature(colder equals lower KΩ values).

Interesting to note Gibson PUs show more fluctuating DC-resistance values than Epiphone PUs which are noticable consistant. If I were to speculate I'd say the Gibson pups were deliberately wound to "approximates", to mimic fluctuating DC-resistance values just like in the old days.

I've posted early roughdrafts on the Epiphone and Epiwiki forum before, and have seen it randomly copy/pasted elsewhere, including the inaccuracies. The MLP-version is the only version I will keep updated.

Comments, corrections and additions very much appreciated.

Planned feature: Pics!

Interesting bit of work there! Thanks for taking the time to start this compilation! Many of the Gibson pups are hard to identify by outward appearance. :applause:

Thanks so much for this, I have been looking for a list like this for some time! A quick correction, however. The Jimmy Page Burstbucker Pickups are A3, not A5. The Jimmy Page #2 Burstbucker (bridge on his #2 LP) is an A5. The neck pickup on #1 is around 8.2k and the bridge a little hotter. Same range for the #2. Basically they are a Burstbucker 2&3 set with different magnets.

Tnx! Not-potted I presume?

Gibson Jimmy Page#1.................(Alnico3)...................8.2KΩ(neck)/8.5?KΩ(bridge)
Gibson Jimmy Page#2...........(A3 neck/A5 bridge)..........8.2KΩ(neck)/8.5?KΩ(bridge)


Hmm, unfortunately I can't seem to edit my original post?

Not sure, I would guess non-potted but you would have to ask one of the Page #1/2 owners here.

If you want to edit your OP you need to talk to an admin. Better move the whole list to your second post if you plan on editing a lot! :D

I measured my Angus Young SG bridge at 7.60K which is suppose to be an AY pickup, the neck measured 7.64K which is a 57 classic. Is your AG measurement of a real AY or is the "?" speculation. I also have a SG 61 RI with a bridge 57 Classic Plus that measures 10.46K. All my others match what you've posted.

All these DC readings have no value without indicating at what temperature were taken. When given as actual specs, the standard is 20°C/68°F.

If the actual temperature is indicated, you can calculate the actual reading and can calculate how many turns of magnetic wire was used.

Good intentions, faulty procedure.

I've learned this the hard way.

HTH,

What is/was the difference between Gibson p90 T and R?

Thanks.

I was wondering that too, I thought Gibson only made one soapbar that they used for neck and bridge, like how they do with '57 classics (you have to put the classic + in yourself)

Who is Tommy Iommi? Is he Tony's unknown brother or a distant relative?

Gibson Tommy Iommi..........(A2+Ceramic, epoxied).......14.7-17.2KΩ

You're absolutely correct. However... it's not intended as scientific analysis to formulate a math eqation. Just an indication DC-resistance values to be expected in pickups. Temperature fluctuations of 0.1 to 0.2KΩ are to insignificant to deter from the usefullness of this chart in basic PU indentification no?

T-tops from all years are very consistent and around 7.5 ohms
