I have been buying Lee Oskar major diatonic harmonicas & reed plates for many years. Although it is cheaper to replace reed plates than complete harmonicas, it is still very expensive given the time they last. In addition I have had problems with "sticky" reeds & even returned one set for replacement. I have tried contacting Lee Oskar & Tombo direct but have not even received a reply. I subsequently bought a Seidl with stainless steel reeds in D & a Suzuki Pro Master in G & I am delighted with the results. The difference in quality & longevity more than compensate for the extra cost. I shall not be purchasing any more Lee Oskar harmonicas in future.
This is a great way to extend the life of your harps. The reeds are pretty durable compared to other brands. They are easy to fit - instructions included. A small philips screwdriver is required... I use the I use the one supplied in the Lee Oskar tool kit.
