Trembucker spaced vs Regular spaced humbuckers

[freefrog]

No, I didn't mean between a Duncan Trembucker and a Duncan regultar-spaced humbucker. I'm sure there is a difference between those two.

I meant between a Duncan Trembucker and something like a Gibson 500T where the poles have a wider spacing almos as wide as the Duncan, just the top of the bobbins are not as wide as Duncan Trembuckers.

Ah, OK, sorry for the parasitic answer, posted on a hurry. When I was telling that my brain is getting old...

Let's try to react on topic this time. You said in a previous message: "I would assume the internal design of the bobbins where the wire is wrapped around is very similar even if they make the tops of the bobbins wider, isn't it?"

That's something that I'll try to check if I can find the trembucker bobbin previously mentioned. In the meantime, let's share what came to my mind on the basis of my own experience: IF the plastic is thinner between magnetic poles and wire, diminishing the distance between 'em, the coil should tend to sound brighter with the same number of turns of the same wire (and even if it has an higher DCR, since it's the number of turns that counts).

And I keep thinking that something else to take in account with trembuckers is the location of the magnetic bump surrounding each E string, as illustrated by the 10th colored pic in the SKguitar page: https://www.skguitar.com/SKGS/sk/Images/pickups/Pickup stuff/Magnetics.htm

FWIW : another boring rambling posted hastily and therefore subject to change without notice, if ever I realize I was off-track or ambiguous.

Where the poles are isn't the measurement that matters, nor the top of the bobbin. It's the distance around the actual bobbin, which affects the amount of wire on the bobbin.

I'm aware. What I'm trying to say, I guess, is that a Gibson 500T (or a 498T) might as well be along the lines of a Duncan Trembucker in how it's constructed.

That's just me assuming, though. I have no idea how either of them are inside. I'd love to know.

Very interesting. I have no idea how Duncan Trembuckers or Gibson wider-spaced pickups are inside. I wonder how different they really are. Because I've always been curious about what wire gauge the 500T could be. Not sure if it's more related to the Custom or the Distortion since it's 15.2K, so it's higher than a Custom, but lower than a Distortion, but it's spaced like a Trembucker and the bobbins look pretty full.

Well, AFAIK, Gibson said each coil hosted 7500 turns: once correlated to DCR, it suggests 500T are machine-wound with AWG43 (and not too tight, apparently).

HTH.

I think the discrepancy is because Duncan made Trembuckers to work with Fender/Floyd guitars. Gibson when moving to a wider spacing, wasn't trying to make their pickups compatible with Fender for sure.

What's funny is the spacing is slightly wide for the current API bridges. It does matches the Schaller bridges they were using when the 500T and 498T came out, though.
