Sadowsky Spare Parts Electronics & Parts

The Sadowsky Onboard Bass Preamp (4-Knob System) is a completely prewired system offering the same controls and the same legendary active preamp as all Sadowsky basses. This preamp is designed for installation on most basses with a 4-Knob Layout. On newer active electric basses with a 4-knob layout with a side jack and a battery compartment, usually no modification is required. On passive basses, the only required modification is to move the output jack to the side of the instrument and to make room for a battery. The controls are: Volume – Pan (Balance) – VTC (Vintage Tone Control) – Treble / Bass. The treble and bass controls are boost only - flat response is with the controls at their complete counterclockwise position. The VTC control is passive, the maximum setting is a flat EQ. The further you turn the control down, the more the high end in the signal will be attenuated. This system is not compatible with active pickups requiring anything else than a 250K or 500K volume or balance pot.prewired onboard bass preamp for electric basses with 4-knob layout, side jack and battery compartmentactive preamp for passive pickups4 knob layout with controls for Master Volume / Balance / Vintage Tone Control (P/P) / Treble and Bass (stacked)push/pull function at VTC knob for preamp bypassincl. 0.1 µF replacement capacitor for the VTC module for improved treble roll-off when used with Sadowsky Soapbar pickupslonger cables between the potentiometers to facilitate installation in non-Sadowsky bassesscrew terminals on the balance potentiometer for pickup hot & ground wires for solderless installationwithout Control Platefrequency response 5 Hz - 50 kHzBass control offers +18 dB boost at 40 Hz Treble control offers +18 dB boost at 4 kHztotal harmonic distortion (THD) 0.18% at 1 kHzpower supply via one 9V battery (Operating with 18V is not recommended, as this could destroy the circuit)current draw 9 mAup to 870 hours battery lifeinput impedance 1 Mohmoutput impedance 1 kohmNote: Defects or damage caused by improper installation or the use of unsuitable accessories and tools are excluded from the warranty. This includes excessively hot solder joints, incorrect solder and resulting damage to the electronics and solder joints.Note: When installing a Sadowsky Onboard Preamp on 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 because the factory installed potentiometers on the MetroExpress have a smaller diameter than the potentiometers on the Sadowsky Onboard Preamp.Warranty Information for Electronics: Electronic components such as preamps and circuit boards by Sadowsky, MEC, Seymour Duncan, and Bartolini are covered exclusively by the legal warranty period. These items are classified as electronic wear parts and are therefore excluded from the extended 4-year warranty. Thank you for your understanding.

The Sadowsky Onboard Bass Preamp (4-Knob System) is a completely prewired system offering the same controls and the same legendary active preamp as all Sadowsky basses. This preamp is designed for installation on most J-style basses with a metal control plate. On newer active J-style basses with a side jack and a battery compartment, usually no modification is required. On passive basses, the only required modification is to move the output jack to the side of the instrument and to make room for a battery. The controls are: Volume – Pan (Balance) – VTC (Vintage Tone Control) – Treble / Bass – Mid Boost switch. The treble and bass controls are boost only - flat response is with the controls at their complete counterclockwise position. The preamp also features a 500 Hz mid boost that can be switched on/off with a toggle switch. The VTC control is passive, the maximum setting is a flat EQ. The further you turn the control down, the more the high end in the signal will be attenuated. The preamp can be installed either with the included control plate or mounted through a rear control cavity in either a 4-in-line or diamond pattern. This system is not compatible with active pickups requiring anything else than a 250K or 500K volume or balance pot.prewired onboard bass preamp with Mid Boost for J-style basses with metal control plateactive preamp for passive pickups4 knob layout with controls for Master Volume / Balance / Vintage Tone Control (P/P) / Treble and Bass (stacked) / Mid Boost togglepush/pull function at VTC knob for preamp bypassincl. 0.1 µF replacement capacitor for the VTC module for improved treble roll-off when used with Sadowsky Soapbar pickupscan be installed either with the included control plate or mounted through a rear control cavityfrequency response 5 Hz - 50 kHzBass control offers +18 dB boost at 40 Hz Mid Boost switch offers +10.6 dB boost at 500 HzTreble control offers +18 dB boost at 4 kHztotal harmonic distortion (THD) 0.18% at 1 kHzpowered by one 9V battery (Operating with 18V is not recommended, as this could destroy the circuit)current draw 9 mAup to 870 hours battery lifeinput impedance 1 Mohmoutput impedance 1 kohmNote: Defects or damage resulting from culpable or improper installation as well as the use of unsuitable accessories or tools are excluded from the guarantee.
