[Harp-L] comb profile



Regarding comb channel profile, yes. I have made quite a few different channel profiles and can say a round channel sucks.
The top 3 holes lose all response. I also made some with hourglass shaped channels and these had improved response
but not enough to warrant doing full time. Plus it was critical to make sure the Z height (cutter) was dead on or the
profile would be a different width from top to bottom side.
