"The Sound, The Soul, The One"

The technology residing in the Hammond New B-3, XK-5, A-3 Heritage and other Hammond organ and keyboard products is connected to both past and present.  Laurens Hammond's original 1934-35 concepts are now a digital reality.  Others may copy but Hammond refers to the original blueprints, patents, and design concepts proven over the decades.  That's why for 90 years and counting Hammond remains, "The Sound, The Soul, The One."

The A-3 Heritage Organ System

Church Special!  Only $218 monthly with 300-Watt Leslie! Call Us!

Shown above without the optional, matching 25-note bass pedals, the Hammond A-3 Heritage Organ System gets its name from Laurens Hammond's very first organ, the Hammond Model A because  dimensionally, the A-3 Heritage and the vintage Model A are essentially the same size (slightly narrower than the B-3).  The A-3 Heritage offers churches and institutions the look and feel of the Hammond B-3 with a level of portability, should the need arise to move the instrument.  Based on the innovative Hammond XK-5, the A-3 Heritage offers the touch and feel of a vintage instrument thanks to several patent pending technological advancements.

Hybrid Multiple Key-Contact System

On classic Hammond Organs (and in the current, full-sized New B-3 Mk. II family), pressing a key sequentially closes nine mechanical contacts; one for each drawbar. In normal play, your ears hear these multiple harmonics as one note. Depress a key slowly, however, and you hear the harmonics come in at slightly different times. Normal playing created a subtle “slop” between otherwise crisp attacks, and the more drawbars pulled, the more “chewy” and soulful character it imparted to the sound. Some called it “bounce”, and it was also indelicately referred to as “spit”. Many beloved Hammond keyboard “tricks” were born of this unintended imperfection.

These unique responses can’t be accomplished with MIDI single note-on keying, the system used in the majority of today’s keyboards. The XK-5/A-3 Heritage uses three mechanical contacts at different points in the keys’ travel. Each of these, in turn, triggers three virtual contacts, providing a discrete “note on” connection for every drawbar pitch in the same manner as the original nine-contact electro-mechanical Hammond® organ. The result is a fingers-to-music connection perfectly duplicating the response of a Vintage “B” while saving on weight and cost. Plus, the time-spread between these “note-ons” is programmable, as is the order in which the harmonics speak, allowing for totally unique variations in touch and response.

Completely Redesigned Key-bed

The XK-5’s keyboard action is built in-house, not sourced from a third-party manufacturer. It was designed to duplicate the heft, bounce, and key dip of a “new old stock” or well-maintained B-3™: No springy synth keys allowed! Master Hammond players who tested early prototypes confirmed that nothing comes closer to the feel and response they expect from a Vintage Hammond. Of course it has the “waterfall” key fronts critical to Hammond playing techniques such as palm slides and glissandos. Play the XK-5/A-3 Heritage alongside any modern organ other than the A-3 Heritage or the New B-3 organs, and we’re convinced you’ll find the difference stunning. Play the Xk-5/A-3 Heritage alongside a vintage Hammond or the New B-3 and we’re convinced you’ll find the similarity stunning.

All-New Sound Engine

The XK-5 employs new proprietary technology digitally recreating Hammond’s storied tone wheel generator with unprecedented accuracy and flexibility. Tone wheels were spinning discs on shafts, each with its own pickup pointing at the edge. The pattern of “teeth” cut into the edge of the wheel determined the pitch. Modeling and sampling are combined in an exclusive process to capture the frequencies of all 91 tone wheels found in the original organs, along with other important sonic details such as key click, Touch-Response Percussion™, vibrato-chorus, and more.

More Features

Hammond did not stop there.  Just a few of the A-3 Heritage's more than 50 innovations and features include:

• Four full sets of Harmonic Drawbars plus pedal drawbars, just like vintage Hammond console organs including the B-3.
• 12 additional virtual tone wheels are devoted to harmonically complex pedal tones (more than just 16' and 8'), as found on Hammond Organs beginning in 1945.
• Hammond's best-ever Digital Leslie
• Continuously variable Digital Leslie speed, if desired.
• Dedicated octave shift/transpose buttons.
• Improved Vibrato-Chorus
• Crisp new OLED display for easy readability under varying light conditions.

All in all, the Hammond A-3 Heritage is a break-through in sound, cost reduction, and performance.  For the church musician, it is the common sense answer to the "what now?" question when the old vintage Hammond finally gives out.  For the hobbyist, it is an affordable instrument with the features necessary to duplicate just about any vintage Hammond Organ and Leslie speaker combination imaginable.  For those of us at Hammond Central, it is a product we are, therefore, quite proud to represent.

The Hammond A-3 Heritage Organ System is generally available for delivery or shipment within 5 business days.  Churches may lease this instrument together with the Leslie 3300W in matching red walnut finish for just $289 per month.  We have financing plans available for studio musicians as well as the home-hobbyist.  We also generally have one or more demonstration units available at additional savings.  Call us at:
