The Intelligent Harmony Machine’s Moment Mode lets you instantly change pitch by simply depressing the pedal’s footswitch. The pitch shift is engaged as long as you hold down the F/S. There’s also an option so you can apply a user-set sweep time between dry and effect. Choose instant pitch changes or control the time it takes for the Intelligent Harmony Machine to sweep up and down between the set interval and the dry signal!

EHX Founder, Mike Matthews said: “We designed the Intelligent Harmony Machine for the player who craves maximum power, but in a minimal footprint. You’ll dig its sweet, musical tone and spotless tracking!”
