This Freeman Tweaked Generation Bb Brass Whistle is in excellent condition. Generation whistles have long been the standard of Irish and other traditional whistle music. However, in the last few decades, the quality of the mass produced Generation whistles has changed. This whistle has been “tweaked” (the traditional term for fine tuning a whistle) by Jerry Freeman to create as close as possible to an ideal Generation. It has that coveted Generation sound, with it’s beloved “chiff,” but it plays well and easily.
