The Portable Hammond for the Organ-focused Keyboardist

At Sweetwater, the name Hammond commands respect. It’s synonymous with the classic tonewheel organs such as the B3 that played an outsized role in the music revolution of the 1960s and 1970s. In the digital era, Hammond assumed a leadership role in developing cutting-edge “clonewheel” organs that deliver those legendary organ sounds, along with all the other essential keyboard instruments you need for any gig or recording session. The SK Pro represents the latest generation of organ-focused, do-it-all keyboards from Hammond. Loaded with higher-resolution samples than previous SK series instruments and equipped with four robust sound engines that can be deployed individually or in any combination, the Hammond SK Pro ups the ante for breathtaking sonic realism.

Definitive drawbar organs

As a genuine Hammond, the SK Pro is, of course, going to have the state-of-the-art in authentic organ sounds. These come courtesy of its newly developed drawbar organ section, which is derived from Hammond’s flagship XK-5. The SK Pro’s industry-standard Hammond tone is produced by the powerful modeled tone wheel 1 (MTW1) sound engine, complemented by a special system that emulates the matching transformer of a vintage Hammond; while a newly developed virtual multi-contact function replicates the keyboard performance of those coveted models. This modern technology closely follows Mr. Hammond’s original design, but is executed without moving parts in the digital realm, providing all the unique sonic characteristics and imperfections that have come to define the classic Hammond sound. In the factory, the SK Pro is set to the same tolerances as a B-3 was during its production run, but digital control — including the touch-response percussion found on vintage Hammonds — allows you to sculpt nearly every aspect of your sound.

Next-generation digital Leslie

The SK Pro houses Hammond’s next-generation onboard digital Leslie, which features deeper authenticity, including rotor airflow, to faithfully reproduce the Leslie cabinet’s unique tone and 3-dimensional swirling effect. A new tube modeling system provides characteristic tube warmth and gritty growl when driven hard.

Classic transistor combos and pipe organs

Beyond the tonewheel, Hammond’s wave composition system adds the vintage Italian, British, and Japanese transistor combo organ voices, which have come back into vogue in a big way. In addition, the SK Pro offers a full range of pipe organ voices — including a brand-new selection of theater pipe organs. No matter the genre, the SK Pro is ready to ace the gig.

The piano/ensemble engine

The SK Pro also features an all-new piano/ensemble engine with a wide variety of keyboard and other instruments, including acoustic and electric pianos, brass, reeds, strings, choirs, and percussion. The high-resolution samples of the world’s leading acoustic grand pianos are noteworthy, particularly the stunning new “S” sample of a legendary European grand. And for the first time in an SK series keyboard, all piano/ensemble voices can be fully edited. Sample choice, EG (envelope generator), filter, LFO, and other parameters are now under your control and can be saved as a patch. A total of 162 high-definition digital voices (with upgraded resolution compared to previous SK models) provide a broad variety of tonal possibilities. All voices (many new to the SK line) have been carefully curated for their usefulness in real-world musical settings. Onstage, you’ll appreciate the 12 category buttons that allow effortless, instantaneous sound selection, and Hammond’s proprietary ProChord feature (available on many voices) that lets you produce complex harmonies by playing a single-note melody while playing chords with your left hand.

The mono synth engine

The SK Pro packs a beastly physical-modeling synthesizer that faithfully reproduces the sounds of classic analog synthesizers. The mono synth engine offers six different oscillator configurations, as well as controls for filter and amplitude, allowing you to create and tweak your sounds in real time, just as on a vintage analog synth.

Powerful onboard DSP effects

The SK Pro is equipped with a powerful onboard DSP effects engine. Each of the SK Pro’s four voice sections can be assigned overdrive and two types of comprehensive DSP multi-effects. Overdrive flavors include tube, solid-state, clip, and EP amp; and the two multi-effects engines offer tremolo, wah, ring modulator, compressor, phaser, flanger, chorus, delay, and auto pan.

Combinations and favorites

The SK Pro introduces combinations to the SK series, which allow you to prepare patches from any or all of its four tonal sections, along with your desired performance parameters. You can also assign external MIDI instruments to these combinations. combinations set you up for each performance and can be changed in an instant. In conjunction with the four allocation buttons in the center of the keyboard, you can call up any part of a combination in real time, giving you the equivalent of four discrete keyboard instruments. In all, 200 combinations are available (100 Factory, 100 User). For instant access, any 10 of these may be assigned to the favorites buttons (as on previous SK models). The role of the favorites has been expanded to include 10 Banks of Favorites, easily called up with a single keystroke.

What is Demo Gear?

At Sweetwater, we're so picky that what we call a "demo" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

What demo means to us is that we've had it out of the box, or maybe it was in a customer's hands for a few days and isn't "factory fresh" as a result. Every demo item we sell has Sweetwater's 2-year Total Confidence Coverage™ warranty, and has been tested and verified up to "new" specs by our factory-authorized technicians to make sure it's in perfect working order before we ship it to you.

When you buy a Demo item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!

Sk pro 61 key

This keyboard by Hammond is the best organ combination yet that I have ever heard The internal Leslie is sound better that what I expected. There are other great tones that sound strong and amazing no cheap or cheesy sounds. I only have 1 regret is that I need a Leslie now! The 3300 would be my choice! I also gotta get the pedal board also!

Over the years I used Roland vk8 with Leslie 3300
Nord c2d with the Leslie 3300
Casio 7600 neo ventilator sounded great also but this skpro has but my ventilator in the closet I tried with this and it still sounded great I want to thank Alex McKinney for all his time and help

GREAT HAMMOND ORGAN

I've had the Hammond XB-2 for stage and recording for many years, but the Hammond Sk PRO sounds great and performs better than most for live play in addition to its light weight. Sweet Water has been very important in making my music sound great with my band The Universals Rock Band. Im 70 and I have played nonstop since 1969, always relying on Sweet Water. The guidance and attentions of my Sales Enginner Bryan Encalada has been unsurpassed. Thank you very much, Cesar E. Santiago

My First Real Hammond!

I've been playing piano for 50 years but didn't dabble with the organ until COVID. As I learned more (and learned what to listen for), I discovered that the Hammond organ was the foundation for most of my favorite classic rock songs from the 70s. I toyed around with the organ section on my Nord Stage 88, but it never really felt like an organ. I finally decided to invest in an SK Pro just for the learning experience, and I have enjoyed every minute of working with it since it arrived. It is probably the most customizable keyboard I have ever owned. There is a steep learning curve with the in-depth OS and all the options, but I can see that with a little study and experience, there's nothing organ-related that I won't be able to do with this board. The keyboard is amazing, and the organ engine is second-to-none. My next purchase? A real Leslie!

Great Organ Piano and Strings

I've had the Hammond C3 and the Cabinet to Match Plus the Yamaha Roland and Korg for stage and recording. This baby sounds great and works better than most for live play.SweetWater has taken great care to make my music sound great with ease. Im 70 and have played non-stop since 1969, I'm sticking with sweetwater. Brent and his crew are sharp as a tack too. Roger Terrell

Totally Blown Away

This is an amazing organ!! I've had several organs over the years, from a Yamaha YC30 back in the 1970s to the Hammond SK2 recently. Now, with the SK Pro, nothing comes closer to the real sound of a B3 (C3, A100, etc.), except possibly the Hammond XK5 which has the same organ engine as the SK Pro! The SK Pro sounds far more beautiful than the SK2. With my old SK2 I needed a Neo Ventilator II and Tall & Fat to have it sound reasonably OK. The SK Pro, on the other hand, is a completely new instrument unlike anything Hammond has ever made. The built in Leslie rotary speaker sounds fantastic! No Neo Vent needed. Plus it has a fully adjustable mono synth, and it has polysynth sounds as well. All the instruments are greatly improved in sound and feel as compared with earlier models. They are all top quality. The keyboard is wonderful to play. The design of the controls is brilliantly thought out. I can't praise the SK Pro enough! Even the color is cool, a dark blue/green. I love it! If you want the best sounding organ you can buy, that plays super well, together with a full range of other instruments that also sound wonderful (pianos, strings, synths, choir, bass, and more), this is the organ for you. It's worth every penny.
