I am part of a music duo called Two Far Gone, and we play pretty regularly in Texas. I play guitar and blues style harmonica using a holder. My Suzuki valved Pro Master MR-350 has gotten a lot of use, and two of the reeds were stuck. My mechanical aptitude is in the minus category, and previously I’ve sent my harmonicas off to be cleaned and repaired. Foolishly, I decided to try and clean the harp myself and loosen the stuck reeds. Imagine my glee when I realized I had succeeded; but when I went to put the harmonica back together to my horror, as usual, I found I was missing one of the casing screws. That meant it was not playable. With a gig coming up the next week, I found these guys online and they are the only ones I personally know of that provides replacement parts for harmonicas, including exotic valved models like the one I play. I ordered the screws I needed and chose one of the faster shipping options. I got what I needed the day of my gig, and I was saved. They specialize in harmonicas, but carry other products as well. If you are a harmonica player, you need to check these guys out. My guess is they’ll have just what you need. 5 stars plus.
