Sadowsky Onboard Bass Preamp 4-Knob

The Sadowsky Onboard Bass Preamp (4-Knob System) is a pre-wired system that offers the same control options and the legendary active preamplifier as all Sadowsky basses. The preamp is designed for installation in most J-style basses with a metal control plate. For newer active J-style models with a side output jack and a battery compartment, no changes are usually required. For passive instruments, the only necessary change is to move the output jack to the side of the instrument and make room for a battery. The control options are: Volume – Pan (Balance) – VTC (Vintage Tone Control) – Treble / Bass. The bass and treble controls boost exclusively - if you turn the controls completely to the left you get a linear frequency response. The VTC controller works passively, the maximum setting is a flat EQ. The further you turn back the controller, the more the heights in the signal are dampened. The preamp can be mounted either with the Control Plate or through an electronics compartment. This system is not compatible with active pickups that require anything other than a 250K or 500K volume or balance potentiometer.
