F spacing?

Im selling 2 Seymour Duncan pup's, the SH2-N Jazz and the SH2 JB, a possible buyer wants to know is they are "F spacing". I must admit I dont know so I looked it up here at this site and the ad's dont give those specs. Does anyone know if those 2 pups are F spaced?
 
Re: F spacing?

If the stickers say “SH-2/4”, no they’re not. If the stickers said “TB-2/4” then they would be.

It’s referring to the spacing of the pole pieces. F=Fender spaced, which is slightly wider. TB= Trembucker, which is Duncan’s name for F spacing.

You can tell the potential buyer that it’s purely aesthetic, which is true, but they likely won’t believe you.
 
Re: F spacing?

You have to measure the distance between to two pole pieces that go under the high and low E strings.

50mm-standard spaces
53mm-F spaced

Im guessing that I measure from the center of each poll, if so then these are 50mm, if measuring from the edge of the polls then they are 53mm.

I no longer have the box's for them but the stickers on the underside of pups themselves say this: 121DY SH-2N Neck and 121DY SH-4. It might help if he told me what guitar it's going in.... I can find out
 
Re: F spacing?

Measure from where the string would be centerd over the pole.

What guitar did this come out of?

Also I think somebody above mentions the stickers on the base plate.
If the pickup model # has an SH designation it’s standard (50mm)
If it has a TB, it is F spaced.

They are standard spaced

Not purely for the looks only. Was a hair band guy running Super Strats and a Floyd back in the day so know why this was done in the first place. If you were running a Super Strat with a high gain amp doing a lot of bends and using the trem aggressively you lost some signal with your E strings at times because they were off the poll pieces. I was running a couple Carvins back in teh day with thier M22 SD mine didn't have the issue others running conventioanl pickups dis so Duncan and Dimarzio gave us the wider F and trembucker poll spacings ( at least those 2 were the first I saw who did) as a solution.

It’s interesting that some people heard signal loss in that instance, when no one has any issues with bending and misalignment.
 
Re: F spacing?

Ive had two guitars, one with a floyd and another with a trem spaced TOM, both of them have had standard spaced SD Distortions in them and I have not heard the first bit of loss. Granted the one with Floyd was stolen years ago, so memory is a bit fuzzy on that one but my Iceman has the wider spaced TOM bridge with a standard Distortion, I hear absolutely no loss.
 
Re: F spacing?

You don't notice any loss with high output pickups. Some people say you can hear it with vintage-output, but I can't.
