Sadowsky 4-knob Bass Preamp is a completely prewired system. It has the same controls and preamp as all Sadowsky basses. Preamp controls are Volume, Pan, VTC, stacked Treble/Bass. VTC=Vintage Tone Control (pull up for total bypass).
Sadowsky 4-knob Bass Preamp can be installed with the included control plate or mounted through a rear control cavity in either a 4 in-line or diamond pattern.
Pickups attach via solderless connectors at the pan pot. Direction of the pan pot can be easily reversed by which pickup terminals are used. Installation requires a side jack and a battery compartment.
Sadowsky recommendations: shielding the control and the pickup cavities. Have the installation done by a professional guitar technician or builder if routing and drilling for a battery compartment and/or side jack is required.
This system is not compatible with EMG or any other active pickups requiring anything other than a 250K or 500K volume pot. For these applications, please custom order a parts only preamp kit and use your original volume pot.
