It's taken almost three years and has seen a number of prototype revisions, but David Levi's Magnetic Cello is finally getting ready for its first production run. Looking like a minimalist version of the acoustic instrument on which it is based, the instrument features a single resistive ribbon on the neck to alter the pitch of a note and a huge, visible coil at the bridge end. Instead of a horsehair bow, the player uses a magnetic rod to induce a voltage in the coil, which is then transformed into a frequency and fed through to the unit's voltage-controlled amplifier. The bow has a small switch at the thumb position which allows the player to select virtual strings.
