Professor’s Notes
The B9 turns your guitar or bass into a living, breathing tonewheel organ—complete with swirl, shimmer, and soul. It tracks every note with uncanny precision and transforms your sound into lush, mix-filling harmonies that feel straight out of a Hammond cabinet. The Professor calls it instant magic—plug in, strum a chord, and watch jaws drop.

Description
The Electro-Harmonix B9 Organ Machine captures the unmistakable character of classic electric organs and delivers them straight from your instrument’s output. Using advanced polyphonic tracking and rich harmonic modeling, it recreates everything from smoky jazz comping to gospel swells and rock anthems. With 9 distinct organ presets, the B9 spans iconic tones—from tonewheel grit and rotary warmth to cathedral shimmer—all without the need for MIDI or special pickups.

Dedicated Dry and Organ volume controls let you blend your natural signal with the synthesized tone, while the Mod and Click knobs add rotary speaker motion and key-click articulation for extra realism. Whether used for textures, full organ accompaniment, or subtle harmonic layering, the B9 delivers expressive, studio-quality sound that fills every corner of the mix.
