Replace existing metal or plastic knob with our Mpingo knob by yourself and enjoy Mpingo effect on your high-end audio system.
You can feel the microscopic vibrations on roots of volume and selector and this vibration is amplified through the knob.

         2) self-made amp., and so there are no possibility to be order from others.
  3. Shipment : need approx. 10~15 business days, normally possible to ship until 2nd~3rd week every month.
  4. Some of parts are need minimum size for solidity due to wood than metal knob.
  5. Starting point (gold color) & set screw bolt groove are located on the opposite side from the center.
