Quick question for the more knowledgable. Ive got a 1980s hohner “the jack” headless bass, it came from a yardsale with the frets pulled and rounds on it. I used my fret saw to clean out the slots and have maple veneer of the proper size to glue in, radius block to to a little smoothing, and a set of la bella double ball end flats....but my main question is whether you put the maple into the slot with its end grain up (like a heavy duty butcher block?) or do you lay the maple in so the grain is going long ways? It seems to me that the end grain would be stronger over time? Any thoughts?
