No longer available at zZounds
At only 15 pounds, the SK-1 keyboard organ delivers what you want from a Hammond: mechanical drawbars, authentic Leslie simulation, Chorus Vibrato, and more.

What do you get when a classic Hammond organ sheds several hundred pounds and jumps into a pair of skinny jeans? You get the 61-key Hammond SK-1, a super-portable, 15-pound keyboard organ that, despite its tiny footprint, still maintains all the traditional features of a complete Hammond organ, like authentic Leslie simulation and mechanical drawbars. Compact and light enough to carry under one arm, the SK-1 is easy to take on tour or from gig to gig. When you're not on the road, tuck it into a corner of your home studio, wherever you make music.

Hammond Organ to the Core

The SK-1 boasts a wide range of extra voices -- something you won't find on other portable Hammonds. Its Drawbar section is a complete Hammond organ with real mechanical drawbars, chorus vibrato, touch-response percussion, and authentic digital Leslie rotary speaker emulation. Also included are Hammond's take on Vox and Farfisa combo organs with their "Vx" and "Farf" models, plus a range of fine classical pipe organ voices derived from a 935 Church Organ. The SK-1's convincing tones come courtesy of Hammond's VASE III digital tone-wheel sound generators.

Extra Voices: Pianos, EPs, Clavs, Strings and More

There's definitely no shortage of voices on this keyboard organ. When you want to go beyond typical organ fare, tap into the SK-1's acoustic and electric pianos, Clavs, accordions, vintage string synths, wind instruments, and tuned percussion. If you crave even more sounds, download more via read more the instrument's USB port. With all these sounds on board, the Hammond SK-1 aims to be the only board you need to bring to the gig.

No Learning Curve -- Just Play!

Offering an intuitive layout, the 61-key SK-1 puts all the traditional controls such as drawbars, Leslie controls, and chorus vibrato on one side of the instrument, and all the unique extras (reverb, master mixer, extra voices) on the other. There's even a music player (WAV, MP3) onboard for when you want to jam along to your favorite tunes.

I have a C3 & 122 Leslie in my studio that I've used for years to record but RARELY took it out on a gig. A friend (who has a B3 & XK3) purchased the SK-1 about a year ago and found it delightful sound wise and for traveling including flying, The Hammond features are real. Drawbars, leslie speed ramping, percussion, vibrato/chorus, waterfall keys, all right on. Programming presets is fairly easy. The other sounds a bonus although I haven't spend too much time with them. The acoustic piano sounds real good on stage as does the Rhodes an Wurlitzer. My compact rig including amp & stand I can move into a gig with one trip using a small folding hand truck. I'm very happy using the Boss expression pedal which is LOT more affordable than the Hammond offering. Did I say it only weighs 15 pounds? :-) Check out some of the Youtube demos online if you need convincing.
