The Electro-Harmonix C9 Organ Machine transforms your guitar or keyboard signal into realistic organ sounds. With 9 presets including Tone Wheel, Prog, and Mello Flutes, it offers a range of classic organ tones. This pedal features controls for Dry, Organ, Modulation, and Click, with separate outputs for the dry and effects signals, and is a great way to add keyboard textures to a guitar rig.
Guitarists found the C9 to be a unique and fun pedal, with convincing organ sounds, especially when paired with reverb. They appreciated its polyphonic capabilities, allowing for easy integration into a band setting. While the construction was good, it wasn't as sturdy as some other pedals and the tracking wasn't always perfect. Some users felt that the pedal required some experimentation to get the best results and that the price was a little steep. There were also comments about the lack of dynamic control for the vibrato effect.
