Hi all. The floor tom on my Slingerland late 50s set is almost impossible to tune on the batter head (a lot of undesired harmonics and it's impossible to get a decent tone out of it). Today i checked the upper rim against the head (remo ambassadors) just to find that the rim is slightly bigger (around 1 to 2 mm) and that this difference is not even, meaning that the rim itself is not round at all.
Do you suggest some methods to correct the rim shape or do you suggest directly to buy a new one ? if so where i can find new (And round) replacements ?
thank you
