Trembucker PG routs?

[rapfohl09]

I was looking through the pickguard builder and noticed that W now offers "trembucker" and "fat trembucker" routs. I was under the impressions that trembucker pickups had the same base as normal humbuckers, just with wider pole spacings, is that wrong?

Now that I think about it, I might be thinking of "F-spaced" vs. normal spacing. Are trembuckers something totally different? I have some F-Spaced dimarzios and didn't notice anything different about mounting them to the rings I bought.

As far as I know (and I could be wrong), the difference is that the fat trembucker routing has a bigger opening that exposes more of the pickup than the regular trembucker routing.

Have a look at the graphical difference, in the pickguard builder.
