An Organ you Want to Touch

An organ expander module without controls to shape the sound would be like a guitar without a neck – it just doesn’t make sense.

This is why we added drawbars and potentiometers – to provide you with the tools you need to find, control and tweak your favorite sounds in a fast and simple way.

Authentic Hammond B3 Emulation

The B4000+ recreates the full sonic bandwidth of the Hammond B3 organ, including all of the functions and features that made the original so special – without the
weight of course!

Housed in a rugged metal enclosure, the B4000+ features dedicated FX, adjustable parameters for key-click, percussion and even the ageing
of the tone-wheels.

All of this makes the B4000+ an authentic Hammond emulation, with full-bodied bass, defined midrange, and highs with the necessary “scream” – just like a genuine electro-mechanic B3.

Plug and Play

The B4000+ features 128 factory-presets by default, which can be expanded by the user.

With just a simple MIDI keyboard (with a MIDI 5pin output) connected to the unit, along with the combination of drawbars, endless encoders and TFT display, the B4000+ will provide you with everything you need to start creating and playing your favorite organ sounds.

Just connect and enjoy!
