A bass preamp with DI function that adds color to your bass sound! The Sadowsky SBP-1 Bass Preamp packs the same electronics that have been built into every Sadowsky bass guitar for over 30 years into an effects pedal. Its flexible combination of preamp and DI box allows you to use it in a pre-amp effects setup or connect your bass directly to a mixer or PA. Control options are simplified to Volume, Treble, and Bass, with Treble and Bass functioning only as boosts. The SBP-1 is ideal for upgrading older vintage instruments where you don't want to change the original electronics, or for bypassing the active electronics in passive basses or active pickups. *The V2 is a minor change with a change in production factory, and there are no changes in specifications compared to the previous type.・Bass +18dB boost (40Hz)・Treble+18 dB boost (4kHz) True bypass Volume/Treble/Bass controls Ground lift switch Bypass footswitch (On/Off) - Mute footswitch - Status LED Metal housing, 6.3mm mono input/output terminal, 6.3mm mono tuner output, XLR output (DI) Powered by a 9V battery or 9V DC adapter (2.1 x 5.5 mm barrel plug, negative center polarity) Current draw: 11 mA・Size (length x width x height) 106 x 107 x 61 mm・Weight: approx. 780g
