The Hammond Sk-1 is the instrument keyboard players have dreamed about, and its wild success proves dreams come true.



The SK1 Stage Keyboard is the most revolutionary HAMMOND yet. This ultra light instrument provides all of the basic instruments that any Keyboard player requires to play ANY show in ANY style. Its slim and compact 15 pound chassis begins with a complete Hammond Organ, with all of the features that you’d expect in a vintage B-3, plus our most advanced Digital Leslie yet. The Extra voice Division provides Hi-Def Acoustic and Electric/Electronic Piano, Clav, Harpsichord, Accordion, Wind, Brass, Synth and Tuned Percussion voices, which you may play solo or add to the Organ voices. The Organ Generator may be switched to modes that provide the authentic voices of British and Italian Transistor Combo Organs whose unique tones have had a 21st Century resurgence. The fourth Organ mode calls 32 ranks of Genuine Classical Pipe Organ voices derived from our Flagship Model 935 Church Organ.

Like all our models, the SK1 has deep editing capabilities that allow the user to tailor the SK1 to their exact taste, and save their work to any of the 100 user presets. The 100 factory presets remain in static memory, for convenience and reference. The Fatar semi-weighted keyboard is designed to feel like a vintage B-3, yet remains comfortable for any pianist playing it. There is an expandable Library of additional voices which may be added, available free from the Hammond Website. An Mp3/WAV music player is onboard to play backing tracks, break music, educational aids or any other tunes combined with the SK1’s stereo output. You may also direct connect a physical Leslie Speaker via the 8pin dedicated Leslie Jack.

    “After playing the Sk1 this will certainly be my main gigging axe for everything keyboard I do. I will be using it on the next Hall & Oates tour as well which starts at the end of this month and goes for a few weeks. As well as any future TV appearances we do. BTW the band on LFDH and Daryl all commented on how great it sounds.”
