Tonearm effective mass


If you add more weight to the counterweight on a tonearm does the tonearm effective mass go up or down?

Thanks

Dear Badcap: Go up but the change in the effective mass will be small due that the counterweight is near the tonearm pivot.

If you need a significant change in the tonearm effective mass and if you can then you have to do it at the tonearm headshell position.

Dear Doug: The question speaks to add weight to the counterweight, IMHO if you add weight at any position of the counterweight the effective mass goes up against the original one ( obviously with out change in the original counterweight position. ).
A plain answer to a plain question.

Dear Quidity: I'm just saying that the thread question was a plain one ( almost a yes/no. ) where you can choose to answer in the same plain way ( like me ) or in more wide way like Doug, that's all, please read the question again.

I know perfectly how " works " the effective mass subject. I'm not in disagreement with you or Doug.

Doug: Yes you are right: my answer was to much plain. But what I was trying to say was that to really make a difference in the effective mass and due that the headshell is at the " farest " position from the tonearm pivot then here at the headshell is a good place to do it, that's all.

Many times I think the things and the explanation only I understand it like a whole, like in this time. I will try to be more precise.
