weird, my now 31 year old (#wow) 500T measures 50 mm and my bridge is 2-1/16" with no misalignment of strings to pole pieces.
True, but if I'm getting either new, and I have the choice for it to match the aesthetic I'm going for, I don't see why not choose the one that matches the spacing the best.When the pickup is 500T/Distortion hot, spacing really doesn't matter.
Also, the reason why I brought the spacing up is because the 500T is actually closer to a Trembucker by Duncan's standards. Duncan Trembuckers usually have a higher DCR because of the wider bobbin. So it would be more apples to apples to compare the 500T's DCR to the Distortion TB-6's than to the SH-6b's, I would think.

I just checked... the bobbins on the 500T are also wider than on the standard-spaced Duncans I have lying around. It's not just the pole spacing.Duncan's "Trembucker" bobbins are physically longer than Duncan's standard-spaced models. In contrast, most pickup mfrs simply space the poles wider inside the traditional bobbin geometry for their F-spaced/52-53mm models.
For example, a standard-spaced DiMarzio and an F-spaced Dimarzio both use bobbins that are ~65mm long.
A "Trembucker" uses bobbins that are ~70mm long, compared to "SH" models at ~66mm long. I don't have any Gibson pickups on hand to check at the moment, but I'd hazard a guess that they simply use a wider pole spacing on standard-length bobbins, similar to what DiMarzio does.
It's that extra bobbin length of Duncan's TB models that results in an increased DCR due to the extra wire needed to cover that additional length with each wind. But also keep in mind that a "JB" in standard spacing at 16.4K and "trembucker" spacing at ~17K sound 99% identical.
On the other hand, taking a standard-spaced model and winding it up to that same "~17K" value would give you a noticeably different sound.
