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 ax and create a cool "Riders on the Storm"-style groove or hot funk like "What'd I Say!" . Each preset allows you to control the fundamental parameters that help define the sound of that instrument. Many include adjustable modulation like tremolo, phaser, and chorus. Take if from Mike Matthews who says, "You're going to dig how KEY9 turns you into a Rhodes Scholar!" 9.6VDC 500mA power supply included.
