GET THE MOST OUT OF YOUR KEMPER PROFILER AND REMOTE. The linear potentiometer is matched exactly to the specifications of the Kemper Profiler for precise and natural response. The standard pedal has a toe switch to turn effects on and off without requiring a separate footswitch. The optional spring load omits the physical toe switch. The spring always returns the pedal to heel down and is used with the Profilers auto-on function to automatically turn the wah effect on and off when moving the pedal. The EP1-KP is available in green or black finish, and works with the rack and head versions, the Remote floor controller and the Stage.
