I need to purchase a few leathered pre-tuned reeds for an older Patti-Bros used accordion that I have. I’m not a professional repair person by any means but I think I can do it myself after watching videos and being kind of handy. Does anyone know where to get reasonably costing accordion reeds, reed wax, etc. online either in the USA, or that ship to the USA? Multiple sources would be good. Thx.
