It's okay to get fret work or fret replacement done by a
competent luthier or repair tech. I can assure you that
every pro you see playing a fretted bass that is a vintage
piece has had to have fret work done at some time.
Do some searching in your neck of the woods so to speak;
to find a good guitar and instrument repair shop that has
a good rep for fret work. They can tell you if you need
a fret dressing or some fret replacement done.
You won't be hurting the vintage vibe or value by having
a bit of fret work done to make your bass playable as an
instrument. Consider it as if you owned a super clean 1957
Chevy that needed the tires replaced with new 50's spec
replica tires or maybe the car needs new spark plugs.You'd
get the repairs done. I wish you the best of luck.
