This MacMaghnuis whistle is tuneable and is made from Boxwood and is in the key of C
This is a wide bore whistle that is very responsive in both octaves giving strong clear notes. As Phil Hardy says in his video review, the build of Roy MacMaghnuis whistles are match perfect to that of the Oz Whistles. This latest version of the MacMaghnuis whistle has a strong bright tone with flute overtones. An ideal whistle for playing in sessions as the volume is very strong.
