I had some polystyrene plastic I used for fret slot filler on some fretless conversions, and I cut some with a pair a scissors for my jazz bird.. just needs a thunderwoodstock….
I used 3m double sided tape

IIRC when I bought my early model VP (first run of Eppi VPs) they were advertising the fretboard material as “Black tech”, an engineered wood based product, not actual slab cut wood. But that’s just my recollection, I can’t seem to find anything on the web to confirm that.
i remember that, didn’t they go to laurel wood for fingerboards sometime after?
