I bought a new guitar that had these installed but I swapped them out for another set. I bought the guitar November 2020 and swapped the pups out January 2021, so there is very little play time on these; they're essentially brand new (been sitting on a shelf for a few years).
Here's what Duncan says about this model:
The ’59 neck model (SH-1n) is one of our most popular pickups because it’s so versatile. Like its bridge-position sibling, the ’59 neck is designed in the spirit of the original P.A.F. humbuckers of the 1950s, with sweet sustain, and a warm, full sound that still possesses a clear attack. We’ve made a few refinements to slightly modernize the design and make it more adaptable to different styles. The high end is slightly boosted for improved pick-attack clarity and the mids are a little scooped for an open, smooth sound that’s great for preserving the clarity of the individual notes in a chord. The ’59 neck was born to accompany the ’59 bridge, but countless players pair it with a high output bridge humbucker, such as a JB or Custom. It’s also a popular choice for humbucker-routed Telecasters.
