articleNumber => protected'SAC ELE OBOARD BP4F' (19 chars) teaser => protected'' (0 chars) description => protected'The Sadowsky Onboard Bass Preamp (4-Knob System) is a completely prewired sy
      stem offering the same controls and the same legendary active preamp as all
      Sadowsky basses. This preamp is designed for installation on most basses wit
      h 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 jac
      k 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. T
      he treble and bass controls are boost only - flat response is with the contr
      ols at their complete counterclockwise position. The VTC control is passive,
       the maximum setting is a flat EQ. The further you turn the control down, th
      e more the high end in the signal will be attenuated. This system is not com
      patible with active pickups requiring anything else than a 250K or 500K volu
      me or balance pot.

      stem offering the same controls and the same legendary active preamp as all
      Sadowsky basses. This preamp is designed for installation on most J-style ba
      sses 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 pass
      ive 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: Vo
      lume – Pan (Balance) – VTC (Vintage Tone Control) – Treble / Bass. The trebl
      e and bass controls are boost only - flat response is with the controls at t
      heir complete counterclockwise position. The VTC control is passive, the max
      imum setting is a flat EQ. The further you turn the control down, the more t
      he high end in the signal will be attenuated. The preamp can be installed ei
      ther with the included control plate or mounted through a rear control cavit
      y in either a 4-in-line or diamond pattern. This system is not compatible wi
      th active pickups requiring anything else than a 250K or 500K volume or bala
      nce pot.

      stem offering the same controls and the same legendary active preamp as all
      Sadowsky basses. This preamp is designed for installation on most basses wit
      h 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 jac
      k 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. T
      he treble and bass controls are boost only - flat response is with the contr
      ols at their complete counterclockwise position. The VTC control is passive,
       the maximum setting is a flat EQ. The further you turn the control down, th
      e more the high end in the signal will be attenuated. This system is not com
      patible with active pickups requiring anything else than a 250K or 500K volu
      me or balance pot.

      stem offering the same controls and the same legendary active preamp as all
      Sadowsky basses. This preamp is designed for installation on most basses wit
      h 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 jac
      k 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 respons
      e is with the controls at their complete counterclockwise position. The prea
      mp also features a 500 Hz mid boost that can be switched on/off with a toggl
      e 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. This system is not compatible with active pickups requiring a
      nything else than a 250K or 500K volume or balance pot.

      stem offering the same controls and the same legendary active preamp as all
      Sadowsky basses. This preamp is designed for installation on most J-style ba
      sses 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 pass
      ive 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: Vo
      lume – Pan (Balance) – VTC (Vintage Tone Control) – Treble / Bass – Mid Boos
      t switch. The treble and bass controls are boost only - flat response is wit
      h 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 atten
      uated. 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 patt
      ern. This system is not compatible with active pickups requiring anything el
      se than a 250K or 500K volume or balance pot.

      stem offering the same controls and the same legendary active preamp as all
      Sadowsky basses. This preamp is designed for installation on most J-style ba
      sses 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 pass
      ive 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: Vo
      lume – Pan (Balance) – VTC (Vintage Tone Control) – Treble / Bass – Mid Boos
      t switch. The treble and bass controls are boost only - flat response is wit
      h 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 atten
      uated. 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 patt
      ern. This system is not compatible with active pickups requiring anything el
      se than a 250K or 500K volume or balance pot.

      stem offering the same controls and the same legendary active preamp as all
      Sadowsky basses. This preamp is designed for installation on most basses wit
      h 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 jac
      k 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 respons
      e is with the controls at their complete counterclockwise position. The prea
      mp also features a 500 Hz mid boost that can be switched on/off with a toggl
      e 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. This system is not compatible with active pickups requiring a
      nything else than a 250K or 500K volume or balance pot.

articleNumber => protected'SAC ELE OBOARD BP4F' (19 chars) teaser => protected'' (0 chars) description => protected'The Sadowsky Onboard Bass Preamp (4-Knob System) is a completely prewired sy
      stem offering the same controls and the same legendary active preamp as all
      Sadowsky basses. This preamp is designed for installation on most basses wit
      h 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 jac
      k 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. T
      he treble and bass controls are boost only - flat response is with the contr
      ols at their complete counterclockwise position. The VTC control is passive,
       the maximum setting is a flat EQ. The further you turn the control down, th
      e more the high end in the signal will be attenuated. This system is not com
      patible with active pickups requiring anything else than a 250K or 500K volu
      me or balance pot.

      stem offering the same controls and the same legendary active preamp as all
      Sadowsky basses. This preamp is designed for installation on most J-style ba
      sses 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 pass
      ive 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: Vo
      lume – Pan (Balance) – VTC (Vintage Tone Control) – Treble / Bass. The trebl
      e and bass controls are boost only - flat response is with the controls at t
      heir complete counterclockwise position. The VTC control is passive, the max
      imum setting is a flat EQ. The further you turn the control down, the more t
      he high end in the signal will be attenuated. The preamp can be installed ei
      ther with the included control plate or mounted through a rear control cavit
      y in either a 4-in-line or diamond pattern. This system is not compatible wi
      th active pickups requiring anything else than a 250K or 500K volume or bala
      nce pot.

      stem offering the same controls and the same legendary active preamp as all
      Sadowsky basses. This preamp is designed for installation on most basses wit
      h 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 jac
      k 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. T
      he treble and bass controls are boost only - flat response is with the contr
      ols at their complete counterclockwise position. The VTC control is passive,
       the maximum setting is a flat EQ. The further you turn the control down, th
      e more the high end in the signal will be attenuated. This system is not com
      patible with active pickups requiring anything else than a 250K or 500K volu
      me or balance pot.

      stem offering the same controls and the same legendary active preamp as all
      Sadowsky basses. This preamp is designed for installation on most basses wit
      h 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 jac
      k 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 respons
      e is with the controls at their complete counterclockwise position. The prea
      mp also features a 500 Hz mid boost that can be switched on/off with a toggl
      e 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. This system is not compatible with active pickups requiring a
      nything else than a 250K or 500K volume or balance pot.

      stem offering the same controls and the same legendary active preamp as all
      Sadowsky basses. This preamp is designed for installation on most J-style ba
      sses 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 pass
      ive 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: Vo
      lume – Pan (Balance) – VTC (Vintage Tone Control) – Treble / Bass – Mid Boos
      t switch. The treble and bass controls are boost only - flat response is wit
      h 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 atten
      uated. 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 patt
      ern. This system is not compatible with active pickups requiring anything el
      se than a 250K or 500K volume or balance pot.

      stem offering the same controls and the same legendary active preamp as all
      Sadowsky basses. This preamp is designed for installation on most J-style ba
      sses 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 pass
      ive 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: Vo
      lume – Pan (Balance) – VTC (Vintage Tone Control) – Treble / Bass – Mid Boos
      t switch. The treble and bass controls are boost only - flat response is wit
      h 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 atten
      uated. 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 patt
      ern. This system is not compatible with active pickups requiring anything el
      se than a 250K or 500K volume or balance pot.

      stem offering the same controls and the same legendary active preamp as all
      Sadowsky basses. This preamp is designed for installation on most basses wit
      h 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 jac
      k 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 respons
      e is with the controls at their complete counterclockwise position. The prea
      mp also features a 500 Hz mid boost that can be switched on/off with a toggl
      e 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. This system is not compatible with active pickups requiring a
      nything else than a 250K or 500K volume or balance pot.

Sadowsky Guitars: Sadowsky Onboard Bass Preamp (4-Knob System, with Control Plate)

Sadowsky Onboard Bass Preamp (4-Knob System, with Control Plate)

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.
