This Cillian O'Briain Improved Feadog D Whistle is brand new, never been played (except to assess it, of course). Those of you familiar with O'Briain's improved whistles know these are excellent instruments! It takes very little air to play it, so if you're accustomed to a whistle that takes a lot of air, this will be a bit of a change! It's really efficient with the air you give it and is very precise with a nice, clear, bright tone. These really are a must have in the arsenal for whistle players-it's been one of our favorites over the years and we think you'll like it too.
