Sadowsky Onboard Preamp 3 Knob Assembly Harness Kit with Vintage Tone Control

For the first time, Sadowsky’s preamp is available as a pre-wired drop-in for J style basses WITHOUT a side jack. No soldering required for installation.

The Sadowsky 3-knob Onboard Bass Preamp is a completely prewired system offering the same preamp as all Sadowsky Basses.

It has been designed for minimally invasive installation on most J-bass style instruments.  The only modification required is a battery compartment, which can be hidden under a pickguard or routed in the back of the instrument.

The 3-knob Onboard Bass Preamp can be installed with the included control plate or easily transferred to another control plate or pickguard or installed in a rear control cavity.

Controls are vol/pan/treble-bass. Pulling up on the volume control bypasses the preamp for passive operation.

Pickups attach via solderless connectors at the pan pot.  Direction of the pan pot can be easily reversed by which pickup terminals are used.
We recommend shielding the control cavity and pickup cavities at the time of installation.  We also recommend installation by a professional guitar technician or builder if routing and drilling for a battery compartment 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.
