I pulled these out of a Sadowsky bass I recently bought. The previous owner told me they were Nordys. They look like the pictures Nordstrand has on there website for NJ5s ...

... notice the same wire coloring. The black covers have "Sadowsky" labelled on them, my guess is whomever installed them in the Sadowsky wanted to keep the Sadowsky name.
They work and sound great.
Since they fit a Sadowsky (19mm spacing at bridge), I don't think they will fit a Fender 5. Looks like Nordy makes a specific model for Fender 5s.
