A Walnut fretboard features a well-balanced tonal character from low to high end. The Walnut bridge transfers string vibration directly to the body, delivering a natural and warm tone. This bass is outfitted with a special finger rest. The design allows players to position their thumb across a wide span of the instrument, based on what is most comfortable and appropriate for their playing style.
