I just bought a Yamaha 32A. It is really differentiated, but my copy is not in such good condition. It needs a deep cleaning and it has a small leak. I tried to open it, but I noticed that internally it is very different from the P-32D. For example, I could not access the reeds. Any tips on how to do this on Yamaha Pianica 32A? Another thing, I read the forum material on how to perform a cleaning by means of a “bath” but I do not know if this procedure is indicated to this model of melodica. What do you think?
