Electro-Harmonix B9 Organ Machine Guitar Effects Pedal

The B9 Organ Machine from Electro-Harmonix gives guitarists and keyboardists alike the ability to summon instantly recognizable organ sounds with the stomp of a footswitch. This pedal packs nine presets tuned to capture the essence of the most iconic organs, from tonewheel and combo to cathedral and bell organs. With controls over percussive key clicks and modulation, players can customize each preset to suit their needs. The B9 also features dual outputs, allowing complex routing options for studio and live use.

Authentic Presets Span Genres and Eras

The B9 contains presets for jazz, rock, gospel and more. Fat & Full adds octaves above and below for a huge tone, perfect for any ensemble. The Jazz preset captures the smooth sound of Jimmy Smith’s organ. Gospel employs upper octave drawbars for a soul-stirring tone. Classic Rock emulates the iconic Procol Harum sound. Bottom End focuses on lower drawbars, ideal for basslines like in “Green Eyed Lady.” Octaves uses fundamentals and octave above for a Led Zeppelin vibe.

Effects Shape Each Preset

Each preset includes modulation tailored to the sound, such as rotary speaker, tremolo or vibrato. The Cathedral preset, for example, features tremolo that, when cranked through reverb, creates a psychedelic wash of sound. The Continental preset uses vibrato to conjure ’60s combo organ tones heard in songs like “96 Tears.” The Bell Organ preset layers electric piano and organ, with tremolo on the bell and chime tones.

Click Control Adds Percussive Punctuation

The B9 provides control over the percussive “click” associated with tonewheel organs. Engaging the click on the Octaves preset adds higher harmonics for a striking effect. On the Bottom End preset, the click helps craft a bassline with articulation. The Bell Organ preset uses the click to blend in bell and chime tones.

Complex Routing Made Simple

With dual outputs, the B9 accommodates complex rigs. Players can send the dry signal to one amp and the wet signal to another or connect the pedal to a mixing board to layer organ and guitar tones. Creative routing options abound with the B9.
