Note: When installing a Sadowsky onboard preamp in a MetroExpress bass without a control plate (Modern, Verdine White and M/J models), the holes in the body for the potentiometers must be enlarged. This is due to the fact that the factory-fitted potentiometers of the MetroExpress have a smaller diameter than the potentiometers of the Sadowsky Onboard Preamp
