From the EHX website:
“The new C9 Organ Machine springboards off the revolutionary B9 to mine another rich vein of classic gold and provide players with nine more definitive organ and keyboard sounds.
The C9 will transform your instrument into a convincing full body, electric organ or vintage electronic keyboard. For each preset chosen, it also provides precise control over important elements of that sound’s sonic fingerprint like percussive click, modulation, attack/sustain, drawbar setting or high frequency content. Blend your dry signal to create beautiful layers. Lovers of classic organ and keyboard rejoice!” Check out EHX pedals on eBay.
