The Frog Moving Coil cartridge from Van Den Hul is custom handbuilt with the coil of a GRASSHOPPER III and the frontpole and suspension of the GRASSHOPPER IV: the best cartridge available for its price.
The FROG (standard version) has an output 0.65 mV/channel, matched crystal copper-wire coils, solid Boron cantilever and an extra internal support magnet.
