Using a harmonica stand leaves your hands free to play a guitar or other musical instrument along with a harmonica. The HH01 harmonica stand is designed for use with most 10-hole harmonica models, making it smaller and lighter than some other models, but it still offers a rubber collar and sturdy frame. Double wing nuts are used to lock it in the playing position - put your harmonica in and you're ready to go. One size fits all and the unit easily locks in place at any distance from your mouth.
