Our Magna Koppar reeds are made of long lasting, easy bending, resilient phosphor bronze, and they’re backed by Bushman’s 60 Day No Blow-out warranty. Available in keys:  C, A, D, G, Bb, and F these high quality replacement reed plate sets are a money saving alternative to throwing out harmonicas that have fallen out of tune or become unplayable. They are the same reed plates used in our post 2019 Bushman Delta Frost series of harmonicas, including: Bushman Delta Frost Original, Bushman Delta Frost Steele and Bushman Delta Frost Woody. They do not fit Delta Frosts made prior to 2019, BUT they do fit many other popular harmonicas, including: Kongsheng Bluebird, Kongsheng Solist, Kongsheng Mars Black, Suzuki Promaster and Suzuki Manji.
