Yesterday I’ve cleaned my Suzuki M-32C. I’d take it apart piece by piece. I’m afraid the water is not useful to the key springs and the felt pad under the keyboard.
I used dishwashing liquid. And in addition I applied medical alcohol for reed plates.
Since the melodion was disassembled, I also tuned the reeds.
I’ve just noticed, online stores in Russia sell em brand new…
…and found this:
A week ago I’ve noticed friction between white keys (small-octave B and 1-line octave C) on my Yamaha P37D. It was very noisy and annoyed me. To remove this defect I had to swap small octave and great-octve B keys.
Suzuki is much better made.
When I’ve received my P37D, my impressions was the same. Sticky keyboard as compared to my Suzuki. I was disappointed. But after a couple of weeks the keyboard got used to or me used to. And now Yamaha is my main instrument.
