Colossus. Reborn.

The B4000+ combines the legendary unique Hammond B3 organ sound with modern design and ease of use. Built like a tank, the tone module features 9 real drawbars. With high-resolution endless potentiometer knobs, a TFT display, and full MIDI control, the B4000+ packs the authentic sound of the mighty B3 in a lightweight package – ready to travel around the world in your shoulder bag.

Based on the incredible processing power of a Sharc DSP and a Cortex 3 ARM, all the features of the glorious ancestor have been modeled with the highest accuracy. Starting with 91 tonewheels, including leakage and condition – digital “Clonewheels”. Adding full polyphony, scanner vibrato, tube amplifier emulation with overdrive, and – of course – a convincing rotating LeslieTM speaker simulation. Even the notorious key clicks and percussion sounds are reproduced just like in old times.

The B4000+ allows it to connect up to two keyboards via the MIDI ports plus pedal and sustain controllers for the full playing experience. The integrated Split Mode allows it to split a keyboard for the upper and lower manual on two sections. MIDI data is also transferred via USB. All incoming MIDI data is transferred to the PC via USB and can be recorded in a sequencer.

The B4000+ can feed an external audio signal into the internal effect section, e. g. the rotor and reverb effects. The signal can either be fed directly to the mix or pass through the effects section.

The perfect and highly affordable solution, if there are keyboards, but no ultra-realistic organ tone module in-da-house.
