The pearl eye on the TEDESKA cartridge has no function. It serves as a pure adornment like the one on the frog of a violin bow. But if you insist on having a function, I would quote an old lesson from the lutherie school "Place your right thumb on the frog, it will not be long before a melody sounds"
Fully handmade moving-coil system. Tailored cartridge, especially to your needs.
Fully hand-made lead-wires for TEDESKA half-inch systems.
