Suggested hints on modifying the clipped-wing, V-cut type call:
This call design is becoming one of my favorites. Two ways of improving the sound quality if your initial design isn't quite right (or if you buy this call design and it is not sounding the way you want it to):
1) shaving the clipped edges down in very small increments can greatly improve the roll-over, pitch, and tonal quality,...as well as the ease of controlling volume of the call. I have found that the amount of secondary reed exposure you end up with when clipping is important.
2) deepening the V-cut (one or both sides,...also in very small increments) will generally increase rasp.
...Just a couple of suggestions for those who might be trying this call design....
