Virtual Organ


Colossus. Reborn.

The B4000+ packs the legendary Hammond B3 organ into an ultra compact box. Nobody would build a guitar without a neck, without it, it just will not work. That’s why we’ve developed the B4000+, with nine drawbars: to touch, to screw, but most important: to play!

Based on one of the best and most powerful digital signal processors on the market, the Sharc DSP by Analog Devices, the sound and warmth of the B3 has been carefully recreated down to the last detail – with all the electrical and mechanical inefficiencies that made the instrument a legend.

Just as the real organ with voluminous bass belly, defined mids and indispensable “scream” in the heights: the authentic sound of a living electromechanical B3.

The B4000+ simulates all 91 Tonewheels, if desired, with crosstalk, and mechanical wear. All of course fully polyphonic, with scanner vibrato, tube amp and reverb, and – not to forget – the legendary Leslie. Everything perfectly simulated and adjusted.

Only the weight of the original B3 we have reduced a bit.

Two MIDI ports allows easy connecting two keyboards to the B4000+ without a MIDI merger, for playing both the upper and lower manual. For a full featured B3 simulation, a pedal manual can added too, making up to three manuals that can be played simultanously, with full polyphony. Additional TRS plugs allow to connect a foot pedal, for volume, and a switch, for sustain or rotary speed switching. If only one keyboard is used, its still possible to play two manuals by using the internal split mode. MIDI data is also transferred via USB, to record the MIDI data to the sequencer, or for playback from sequencer.

External analog signals can be fed into the B4000+ by using the analog input plug. It will be merged with the B4000+ sound at any point of the effects chain.

The B4000+ is the perfect and highly affordable solution, if the legendary organ sound is needed in a pocket size format.

The Allmighty Tonewheel Organ.

Hammond organs are towering over the 20th-century music like the ancient pyramids: massive, potent-sounding, an objects of worship, driven to the edge by keyboard wizards.

Since their first appearance in the 1930s, they were not only be used by generations of church organists but in virtually every kind of music style. Originals are still being used around the world by live bands and in selected studios, which are lucky and can afford the necessary space and costly maintenance.

Originally intended as smaller and much cheaper substitute for pipe organs, which can even be used in the smallest chapel or theater, the revolutionary instrument quickly found its way to Blues and Jazz players, like Count Basie. One of the first customers was Georg Gershwin. The movie song Tico Tico, played on a Hammond by the incredible Ethel Smith, became an international hit in 1944.

As soon as gifted rock musicians, like John Lord or Keith Emerson, got their hands on a Hammond, they created the sound, which leaves a monumental mark on the classic era of live and studio music.

While in the 1960s, almost 50.000 Hammonds lived a sacral life in churches and chapels, the trained organist Jon Lord employed the “hard rock” style on his instrument, even playing his heavy and fast keyboard riffs through a guitar amp. Inspiring legions of followers and setting the standard for modern keyboard players, not only the highly-skilled art of playing, but the original Hammond sound is still an object of desire.

Unfortunately the oversized originals require a regular and costly maintenance, including tuning and costly repairs – the additional LeslieTM speaker system is another reason for the loss of remaining hairs and money.

Around two million Hammond organs have been manufactured. The B-3 was the most popular and influential model, produced from 1954 to 1975. “Hammond gods” like Jimmy Smith, who invented the typical Jazz-organ sound, and Booker T. Jones in R&B, made it even more popular, than its predecessors. Furthermore it was used by nearly all legendary rock bands, including Deep Purple, and left its eternal fingerprint in numerous famous songs.

“Clonewheels”: B3-in-a-box.

After countless attempts to bring the sound of the original B3 in an affordable digital hardware package, the B4000+ finally succeeded. Compared to the efforts to maintain a real organ and deal with the incredible weight, the B4000+ is simply a blessing.
