The Expression Ramper HK transforms any expression-enabled pedal into a dynamic, evolving instrument. By defining two expression positions—A and B—you can smoothly sweep between values or continuously modulate them using a built-in LFO, all without the need for a traditional expression treadle.

Its compact mini enclosure makes it an easy fit on any pedalboard while opening the door to rhythmic modulation, automated parameter changes, and experimental textures.
