Completing the powerful trilogy forged by the B9 and C9 Organ Machines, the new KEY9 pedal emulates the world’s most coveted electric pianos and more. With 9 presets, you can transform your axe and lay down a cool "Riders on the Storm" style groove or some hot funk ala "What’d I Say!" . Each preset lets you control the fundamental parameters that help define that instrument’s sound. Many include adjustable modulation like tremolo, phaser and chorus. Take if from Mike Matthews who says: "You’ll dig the way the KEY9 turns you into a Rhodes Scholar!" 9.6VDC 500mA power supply included.
