BassVoice Double is a compact two-channel preamp designed for upright bass systems using a main pickup together with a slap/fingerboard pickup.
It gives both signals their own level control, provides dedicated slap attack shaping, and adds practical tone control to the main bass signal — directly on the instrument.
Designed for players who want to control the pickup signal before it reaches the pedalboard, amplifier or PA.
The main channel works with high-impedance piezo pickups as well as magnetic pickups, while the dedicated slap channel is optimized for fingerboard/contact pickups.
The compact rechargeable unit mounts directly on the bass, keeping the controls within easy reach without requiring electronics to be permanently installed in the instrument.
