Presentation
Aguilar offers you the OBP-2SK, an on-board preamp designed to provide clear, immediately usable tonal control. Its 2-band equalisation allows effective bass and treble adjustment, with a correction range wide enough to adapt the sound to different playing styles.
The active circuit ensures good signal transparency, while preserving the natural dynamics of the instrument. Its 9V or 18V operation offers additional flexibility, in particular to benefit from a greater headroom reserve in 18V configuration.
Its compact size makes it easy to fit into most bass cabinets, even those with small cavities. The double concentric potentiometer optimises ergonomics by taking up less space, while still providing quick access to essential settings.
