The Hammond XK-3c has been designed with the professional musician in mind. Built upon the outstanding features and astounding tone-wheel type sound found on the legendary XK-3 keyboard which is no longer being produced, Hammond engineers have added many of the most requested advanced features and effects never before found on a Hammond keyboard of this price range. Like the XK-3 keyboard, the new XK-3c can be used strictly as a single keyboard or expanded into a two-manual B-3 like organ when used in conjunction with either the innovative PRO or Traditional XK Systems. - 73 keys (61 + 12 preset keys) - Waterfall keys with velocity - Two sets of 9 and one set of two drawbars - Vase III sound generator creates 96 digital tone wheels - Original B-3 reverse color keys presets - Full polyphony (unlimited) - Split upper and lower Vibrato/Chorus switches - Assignable controller for MIDI instruments - Advanced digital Leslie and Vibrato Scanner - Enhanced dual tube preamp and Overdrive
