f spacing & magnets

[45auto]

hey guys, do "F" spaced pickups require wider magnets? i wouldn't think it would be alot of difference, but...

I swapped new magnets into F spaced SD's a while ago with no issues. Just keep the magnet centered and if your high/low E strings don't have enough output adjust the screws or pickup height to taste.

Actually, I think that the slug spacing on the bobbin is the only difference between F Spaced and Normal pickups. I think magnets/baseplates/bobbins are all the same width.

Hopefully someone more versed in pickups will chime in here.

DiMarzios and Duncans are built to different specs. All the dimensions are posted on the Duncan site for the Trembucker the bobbins and base plates are longer. For the DiMarzios I think the length is the same standard but the bobbins are different because the pole spacing is wider.

I meant between F-spaced/Standard spacing versions of the same pickup. Obviously different models will have different bobbins/baseplates.

Do you mean that DiMarzio's F-spaced pickups have completely different bobbins from their standard counterparts? That's weird. Wouldn't that make the F spaced versions totally different animals?

Not sure. The poles are wider apart so if they wind the same weight of copper it would have very slightly less windings and if they wind the same number of windings then it would have less weight in copper. But the difference is probably too small to matter.

Maybe they just wind to the same resistance/inductance etc and just forget about the standard number of turns. Hmm......
