I’m planning a purchase of an Eb whistle soon. Hamiltons look nice, but what about volumne, wind pressure, hole spacing, chiff, spielvernugen?
As far as I know, that might only be available with a Goldie whistle.
Use the search function at the top of the page. Search the Whistle Forum with “Hamilton low whistle”. You’ll see what others are saying.
