Furthermore, users can mix and process Mics and DI separately to get a variety of sound.

ABU uses more mics to record every detail of upright bass from neck, body and ambience and provides 2 stereo modes and 2 mono modes on mix interface. Users can adjust volumes of mics and width to get more options in stereo mode, in which ABU has rich expressiveness even for solo. For mono modes, ABU can play an important role of middle-low end in a band steadily.
