Used for glissando effects and chromatic tone painting to add tone colour to the harmonica orchestra sound. Blow and draw note in each hole have the same pitch.
As well as rhythmic accompaniment, every harmonica ensemble needs a suitable bass. With this 2-voice instrument each channel contains two reeds, tuned exactly one octave apart, giving an extremely fat sound. The lower of each pair of octave-tuned reeds is located on the inner rows of the instrument, ensuring that high and low ranges are equidistant from one another and thus enabling balanced microphoning. For the first time, the mouthpiece of the Bass 58 and Bass 78 models has been integrated into the body, making them remarkably airtight and ensuring matchless response and volume.
