Mcmanus GT Session Whistle.
A new view of the large bore high D.
When I first created the large bore high D whistle I thought that it would only be low whistler that could handle the air requirement, obviously I was wrong. The Busker high D is now a standard whistles whistle. Roy has taken the larger bore D idea and made it into a work of art and practicality. If you like to blow harder and like the feel of wood, this is a wonderful addition to the family. As they say here, " Fill Ye Boots "
