Electro-Harmonix C9 Organ Machine, 9.6DC-200 PSU included

The Electro-Harmonix C9 Organ Machine takes your guitar or bass and drops it straight into the world of classic tonewheel organs and vintage keyboards. Plug in, hit a chord, and it suddenly feels like you’ve got a full electric organ rig sitting at your feet instead of a pedalboard. It’s immediate, inspiring, and one of those boxes that makes you play longer than you meant to.

Features

Building on the concept of the B9, this pedal serves up nine distinct organ and keyboard patches that go from full-bodied electric organ sounds to vintage electronic keyboard textures. A dedicated MODE knob lets you scroll through those presets, while the rest of the controls let you shape each one so it actually responds like the real thing instead of a static sample.

The DRY VOLUME and ORGAN VOLUME knobs let you balance your original signal with the synthesized organ tone right at the ORGAN output, so you can run pure organ, pure guitar, or a rich blend of both. With separate DRY and ORGAN output jacks, you can even split the signals to different amps or signal paths for bigger, more dimensional setups.

The MOD and CLICK controls are where it really gets fun. MOD adjusts modulation speed, giving you everything from a slow, syrupy swirl to a faster, more animated movement. CLICK controls the percussive click level, designed to simulate the classic harmonic percussion effect found on iconic B3 and C3 organs. Between those controls and the internal voicing of each mode, you get precise control over attack, sustain, drawbar-style balance, and high-frequency content—so it feels alive under your fingers instead of just “organ-ish.”

A buffered bypass keeps your signal strong when the effect is off, and the single BYPASS footswitch with status LED makes it easy to kick the organ tones in and out mid-song. Power is handled by the included 9.6VDC-200mA adapter, so you’re ready to drop it on the board and go.

Tone

The C9 is all about convincing, full-body organ and keyboard sounds that track your playing without asking you to change your style. Chords bloom with that familiar organ thickness, single-note lines take on a vocal, singing quality, and the added percussive click can give stabs and riffs a sharp, rhythmic edge. Dial back the ORGAN level and blend in your dry signal for shimmering, layered textures; crank the organ voice and you’re in full-on keys territory. It’s capable of uncanny emulations that respond dynamically, so it rewards everything from delicate comping to aggressive, overdriven riffs.
