This is one of my very first basses. It's an original B.C. Rich Eagle. The electronics have been replaced with EMGs and its strung as a tenor bass, ADGC. The contraption you see on the bottom of the bass is a Yamaha B1D MIDI pickup that plugs into a Yamaha G50 MIDI controller. I've found that the tenor tuning makes it easier for the MIDI pickup to track.
