Sadowsky Onboard Bass Preamp (4-Knob System)
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. 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. 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 for J-style basses with metal control plate
- Active preamp for passive pickups
- 4 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 bypass
- Can be installed either with the included control plate or mounted through a rear control cavity
- Frequency response 5 Hz - 50 kHz
- Bass control offers +18 dB boost at 40 Hz
- Treble control offers +18 dB boost at 4 kHz
- Total harmonic distortion (THD) 0.18% at 1 kHz
- Power supply via one 9V battery
- Current draw 9 mA
- Up to 870 hours battery life
- Input impedance 1 Mohm
- Output impedance 1 kohm
- Note: Defects or damage resulting from culpable or improper installation as well as the use of unsuitable accessories or tools are excluded from the guarantee. This includes soldering points that are too hot, wrong soldering tin and the resulting damage to the electronics and soldering points.
- 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.
