Bit of a bump here, but after having VN pups, heres my conclusion.
Neck sounds awesome, and still retains a good majority of genuine fender tone, and a bit more. It sounds quite stratty.
Bridge is a bit of a let down, not much bass, lacking mids, and very upper treble. All in all not as good as the neck. (this is after countless combinations of pickup height)
as said there is always a compromise. However, these pickups thrive on a bit of gain and thats where they shine, if you're looking for a more modern tele crunch sound. Otherwise, they lack that 'ballsy' single coil grit and mojo that quite frankly makes the hair on your chest go curly.
