These kick everything else to the curb. I have FOUR! BUT you have to use harps with steel covers
My Lee Oscars and Sydels work great. So do Hohners.
Farmer/Sydel Gecko magnetic rack. I add a second neodymium magnet underneath to avoid dislodging the harps.
Brass, plastic, etc will not attach to the magnet…
I have been using these for about 10 years, since I first found one of the original Farmer models.
I would not want one of the magnetic widgets that holds the harp to the mic. Harmonica is LOUD and piercing thru a PA! Have mercy… lean away from the mic!
YMMV, etc
Happy honkin’
