Description
The Ferrofish B4000+ is a masterful tribute to the iconic Hammond B3, packed into a compact desktop module. This powerhouse emulation combines the nostalgic charm of the original with the convenience of modern technology, making it a perfect companion for both studio sessions and live performances. The SHARC DSP and Cortex 3 ARM processor ensure that every nuance, from the enchanting key clicks to the warm overdrive of the tube amplifier, is captured with impeccable accuracy.
With three fully polyphonic manuals, you can orchestrate upper, lower, and pedal tones simultaneously, while the nine physical drawbars provide tactile control over your sound. The B4000+ also excels in its effects processing, featuring a Leslie rotary speaker emulation that can be adjusted in real-time using an expression pedal. This device not only offers the quintessential B3 experience but also allows for creative exploration with its built-in chorus, vibrato, reverb, and compressor effects.
Designed with the modern musician in mind, the B4000+ includes a TFT color display and six high-resolution metal dials for precise parameter tweaking. Connectivity is seamless with USB MIDI, dual MIDI inputs, and stereo analog outputs. Whether you're a purist seeking classic tones or an innovator crafting new sounds, the B4000+ offers an expansive sonic palette wrapped in a robust metal casing.
