B4000+ Tonewheel Organ Module

Imagine capturing the soul of a Hammond B3—those 91 spinning tonewheels with their crosstalk and gentle wear—without hauling around 400 pounds of vintage iron. The B4000+ nails that magic in a featherweight module you can toss in a gig bag.

Powered by a SHARC DSP and ARM Cortex M3, it physically models every nuance: full polyphony across three manuals, realistic keyclicks, percussion with harmonic, attack, and decay controls, plus scanner vibrato, tube overdrive, and a Leslie rotor sim you can tweak from chorale slow to tremolo fast (even blend speeds seamlessly). Nine sturdy mechanical drawbars let you pull classic registrations by feel, backed by six high-res endless metal knobs for drive, condition, and effects like chorus/vibrato, reverb, and compressor. Route stereo inputs through the FX chain, split MIDI for upper/lower manuals, and control via USB/DIN MIDI, expression pedal, or sustain switch—all on a crisp TFT display with 128 presets. At 14.2 x 9.8 x 3.8 inches and just 2.3 kg, it's built tough for the road, with stereo outs, headphones, and velocity/aftertouch response.

Players love how it disappears under your fingers, delivering pro organ tones that gig night after night, though some wish for more preset slots out of the box.[web:1][web:2][web:3]
