Hello Jordan, a few weeks ago I posted a topic “Hohner Melodicas, old vrs new” Where I state this same issue. I have a Hohner piano 36 and a professional 36. Yes there is a lot of slop in the piano 36 in comparison to the professional but it is still a nice sounding melodica in general. I am not sure of a fix for this issues. Is it a prestige looking melodica or does it look like it has been through war? I think in one of the pictures I posted you can see the gaps on my piano 36 and do not see this in the professional.
