Hammond SK PRO-73

SK PRO Series: The Hammond Spirit Designed for Today's Musician

With the SK lineage, Hammond has established itself among keyboardists seeking a true organ playing experience in an instrument that is easy to transport and immediate to operate. The SK PRO 73 continues this tradition by pushing versatility further: an "all-in-one" approach where the organ remains the centerpiece, but piano, ensemble, and synth sounds complement the setup without multiplying keyboards. On stage or in rehearsal, the ergonomics focus on performance: direct access, ready-to-use memories, and sufficient editing to tailor each sound to your playing.

Keyboard Design

Hammond Waterfall 73-key keyboard: the rounded profile facilitates glissandos, palm smears, and smooth register changes, while maintaining a pleasant feel on electric pianos and ensemble textures. The instrument emphasizes real-time control with genuine Hammond drawbars to shape the timbre on the fly. The organ section is organized into three parts (Upper, Lower, Pedal) and offers 9 drawbars, a classic format to regain Hammond playing reflexes and build expressive registrations in seconds.

Sound Quality

The SK PRO 73 relies on three distinct engines to preserve the responsiveness and identity of each sound family. The Organ section offers 61-voice polyphony and 3-part operation (Upper/Lower/Pedal) for complete registrations. The Piano/Ensemble section delivers 128-voice polyphony and provides deep editing (sample selection, filters, envelopes, LFO, etc.) to adjust attack, presence, and dynamics within a band mix. Finally, the Mono Synth section is truly monophonic: perfect for cutting leads, firm basses, and expressive lines, featuring 6 oscillator types, 4 filter modes, LFO, and 2 envelopes. For output, the keyboard integrates easily into your rig via its line outputs, whether you play through a keyboard amp, mixer, or stage system.

Built-in Effects

To finalize your sound without external gear, the SK PRO 73 offers essential stage effects: reverb for depth, chorus/vibrato for color, delay for space, overdrive for energy, rotary speaker simulation for the organ, and equalization to quickly adapt to room acoustics and song style.
