I played several of his before I bought one in February this year . One thing I noticed and David also pointed out. The more Sap wood in the cedar the more rasp the call has. I ended up with one with a lot of Sap and it's nasty raspy. Definitely sounds like an old boss hen.
Good luck with your search you won't be disappointed.
I actually plan on buying a Masscar Ebony over Poplar in the future.
