This hollow body 6-string bass is built with a quilted maple top, curly maple back and sides, with a transparent matte burst finish. One of the biggest features of this model is the Graph Tech Ghost modular pickup system. The system offers Piezo and MIDI output options as well as the magnetic sound. You can quickly and easily control various tones by two knobs and three toggle switches; Piezo/ Magnetic /Mix, MIDI program up/down, and Mid/Dark (natural Ghost acoustic sound/mid-boost) switches. The magnetic pickups are a pair of EMG 45HZ, a passive humbucking pickup which features low noise, plenty of output and warm tone. It maximizes the potential of the Ghost system and acoustic tone of the hollow body to realize Thundercat's unique sound.
