I just got a 335 with the MHS pups, the Wildwood spec 1963 ES 335. It is my understanding that the Wildwood spec pick ups are under wound but I haven't checked them yet. However, I really like the sound of the MHS humbuckers. They have a sweet sound, lots of chime, and seem to cover a lot of tonal territory.
Edited to add: I just checked my MHS pups and they read at 7.9 to 8.0 at the jack.
