Product Specs – Mini-B

AT A GLANCE/BY THE NUMBERS:

GENUINE AND AUTHENTIC HAMMOND ORGAN

With Authentic Chorus-Vibrato/Touch Response Percussion

The Hammond MINI-B is designed to sound and play as close to a “Vintage” Hammond as possible. From the factory, the Mini-B is set with the same OEM factory presets as found on the Original B-3 (Liturgical Set); and the ability to edit/program is locked out to insure against accidental alteration of the Organ. This “lockout” can be defeated at any time to allow personalization, with the knowledge the “Mini-B” original setting can be recalled in an instant. Also, the “Transpose” parameter window remains constant in the display, to easier facilitate the changing of keys. If you change the default Startup to “Xk-3c”, all menus and functions are available.

ALL THESE FEATURES ARE IN EVERY MINI-B/XK-3c

DIGITAL TONEWHEEL GENERATOR

Laurens Hammond’s original Organ (invented in 1935) had an intricate electro-mechanical mechanism that used 96 Quarter-sized wheels spinning on driveshafts powered by his patented synchronous motor. The wheels were notched according to pitch, and an electromagnetic pickup (much like that on an Electric Guitar) sensed those notches and rendered a musical note. The Drawbars combined those harmonic tones to produce the inimitable Hammond Organ sound.

Hammond’s adherence to quality has allowed many vintage instruments to remain vital today, and are among the most desired and imitated musical instruments ever, but at a high cost. The Electromechanical Hammonds require expensive maintenance, regular doses of oil, and were of great weight; not easy to move at all.

The Mini-B/Xk-3c’s VASE III “Engine” uses the exact model of Laurens Hammond’s design, executing it in the digital realm, with no moving parts, retaining all of the nuances, imperfections and idiosyncrasies of the original. The wheels are always “spinning”. When a note is played, the tones pass, just as water through a faucet. The random starts of each wave played allow for phase interaction, producing the rich tone so prized in the vintage Hammonds.

The Digital realization of Laurens Hammond’s System allows sophisticated control of every facet. Each Digital Tonewheel can be voiced for Volume, Timbre, Motor Noise and Leakage; enabling the musician to tailor the Modern Hammond to match the characteristics of any Vintage Hammond, or to create their own vision. Twelve Macro Profiles allow the user to quickly select the most popular “kinds” of Hammond, from Showroom-New to Road-Worn Antique and all points between.

CLASSIC HAMMOND COMPONENTS

The Tonewheel Generator wasn’t the only great invention of Laurens Hammond, and no Hammond Organ would be complete without the full spectrum of ingredients that comprised Mr. Hammond’s genius design.

DRAWBARS

Mr. Hammond used the Pipe Organ Design concept of “Unification” in creating the iconic Drawbars of his Electronic Organ. This concept allowed one or more keyboards to control the pitches of many pipes within one set or “rank” of pipes. Adopting the harmonic standards and nomenclature of the Pipe Organ, Mr. Hammond’s design assured that any organist would be able to play his instrument without a steep learning curve. Unlike the Pipe Organ, Mr Hammond’s design allowed variable volumes of each Harmonic represented by each drawbar. This variation gave the musician millions of combinations of harmonics, and assured that every Hammond player would be able to summon a unique voice. An extra level to the expression a Hammond Organist had at their fingertips was added because the Drawbars could be manipulated in real time. The Mini-B/Xk-3c features real drawbars in the size, shape and configuration of Vintage Hammonds.

VIBRATO/CHORUS

One of the most distinctive parts of the Hammond sound is the shimmering “Chorus Vibrato”. It adds a silken quality to the sound by adding a second, slightly detuned pitch to the original in the Chorus Mode, and repeat-modulating the pitch slightly in Vibrato mode. Few musicians realize the Chorus effect pedal widely used for Guitars and Electric Pianos had its genesis as a component of the Hammond Organ. Mr. Hammond’s original design used an electromechanical apparatus that looked much like the distributors you would find in the automobiles of the day, and ran off the same synchronous motor that powered the Tonewheel Generator. The Mini-B/Xk-3c’s Chorus-Vibrato is executed in the Digital Realm, without moving parts, and works under the same model. The classic Round V1/V2/V3/C1/C2/C3 control is familiar to anyone who has ever played a Hammond. As with the Tonewheel Generator, Digital control allows a wide range of adjustment that was simply not possible on the original. As the Antique organs aged, the components acquired their own unique qualities. Digital control allows the user to shape the Chorus/Vibrato’s various facets, with the added ability to “age” the effect-with the resulting treble emphasis and subtle distortion that marks the organs that develop this patina as “sweeter” than others.

TOUCH-RESPONSE PERCUSSION™

The chief feature of the Hammond B-3 upon its release in 1955 was the inclusion of Touch-Response Percussion™ (Perc). This effect added a high “attack” to the Organ tone at either the octave or the twelfth, with a fast note decay. This sound was reminiscent of an xylophone or clave, and became immensely popular, immediately. Perc gave the Organ a bright highlight, and every generation of music has embraced this sound. Controls for the Perc have the classic nomenclature, familiar to anyone who has ever played a Hammond. On the Mini-B/Xk-3c, Perc is executed in the Digital realm, allowing a wide range of controls the organists back in the day did not possess. The 1′ drawbar muting, characteristic of the Vintage Organs can be defeated, as can the drop in Drawbar volume level that accompanied the engaging of the Percussion voice. You can control the volumes and decay times as well.

KEY CLICK:

In order that every key (and pedal) of the Laurens Hammond’s Organ could access every Tonewheel as predicated by the Drawbar settings, an electro-mechanical apparatus lurked behind the keyboards, with 9 contacts corresponding to each drawbar for that keyboard and a series of contacts attached to each key. As a key was depressed, the contacts sequentially touched, and the circuits were completed to produce the Organ tone that was registered by the Drawbars. The very nature of Electric circuitry dictated a click could be heard at the top of each note played when the current-carrying key contacts touched. Laurens Hammond considered that click to be a nuisance, and charged his engineers to rid his organ of that imperfection. In this instance, they were not successful. The jazz players who embraced the Hammond Organ, however, found the click to be a percussive highlight, and wanted nothing to do with its eradication. To make matters worse, as the Vintage Hammonds aged, the click became more pronounced, and by the Rock and Roll era, the Key Click assumed a role of importance that Laurens Hammond could never imagine. The Mini-B/Xk-3c allows you to adjust the intensity of the key ON click, and the key OFF click. The timbre of the click may also be adjusted. Mr. Hammond would have greatly approved of the Mini-B/Xk-3c, as you can turn the click all the way off if you desire, creating a Vintage Hammond Organ that could not possibly exist in the physical world.

THE “TONE” CONTROL:

The inclusion of this obscure feature demonstrates the commitment to authenticity Hammond has brought to the Mini-B/Xk-3. Inside the Vintage Hammond B-3, on one side of the tube preamp, there was a “Screwdriver Pot” with the engraved legend “Tone”.  It was introduced as a part of Mr. Hammond’s crusade to temper “key click”, but this was never made clear to the public. The “company line” was this control was to be adjusted by the Technician installing the organ in order to tame the treble response in the instance of the organ’s installation in a Church or Mortuary, where a more “muted” organ was desired.  The control was a cocktail of upper Mid and High frequencies (the proportions of which were, until recently, held secret.) The “Tone” control was basically a “hi cut” control and only went “down”. That this control’s presence and location were obscured goes a long way in explaining why there was such a variation in sound among Hammonds. Further, You could not direct the control to go “up” for “boost”. The TONE control is included in the Mini-B/Xk-3c’s menu with the added benefit of being able to BOOST the unique blend of frequencies, which adds a nice “edge” to the Organ’s tone, if desired.

DIGITAL LESLIE™

Chicago Engineer/Inventor Don Leslie bought a Hammond Organ not long after its introduction in 1935, but felt the instrument lacked the warmth of the Mighty Theatre Pipe Organs he so loved. The main difference between Church Pipe Organs and Theatre Organs was the deep Tremulant that took the edge off the Theatre Organ’s pipes and made them emotionally “sob”. Making use of an acoustic phenomenon called the “Doppler Effect”, Mr. Leslie constructed a speaker cabinet that used a simple system of rotating horns and baffles to give the Hammond tone “motion” and “depth”. This created a different instrument altogether, one that could play “Popular” music. Mr. Hammond intended his organ for the Church and Classical Music, looking at “Popular” Music with disdain-he wanted nothing to do with Mr. Leslie’s invention when Mr. Leslie demonstrated it. The public however, took the combination of Hammond and Leslie to heart, and so it remains to this very day. It is difficult to think of one without the other, although Mr. Hammond never allowed Hammond Dealers to sell Leslie Speakers. After Mr. Hammond’s death, the two companies became partners, and now Hammond owns the company, and manufactures Leslie Speakers. For both Hammond and Leslie, the golden goal was to produce a Leslie that did not require motor-driven speakers, and the goal has been reached. As an added benefit to being produced in the Digital realm, many aspects of the effect can be adjusted and tailored to ones own taste and requirement. Slow and Fast Rotor speeds, “Ramp Up” and “Ramp Down” speeds, Speaker Size, Amp type, Virtual Mic Placement and other parameters may be combined into “Cabinet” Macros which then may be assigned to any Organ Preset. In addition, 8 factory Cabinets, comprising the most popular Leslie Models like the 122, 147, 760, Vintage 31-H, and others are available for instant choice. There is even a model of the original PR-40 (Non-Rotating) Hammond Factory Tone Cabinet.
