Medium mass, I believe, but in spite of that, it has been found to work well with high compliance cartridges.

We don't really know, but I tried calculating it a while back using my own turntable and cartridge and here was the result:

Effective mass is not an absolute number, but varies with the mass of the cartridge, the tracking force set and the measured performance of the cartridge at a specified frequency.
