The Electro Harmonix Pico Canyon Echo represents the award-winning circuitry of the original Canyon Echo within the compact Pico series. The digital delay effect creates repeats with delay times of up to 3 seconds, making it a great fit for everything from crisp slapbacks to room-filling multiple echoes. For timed sound effects, the Pico Canyon Delay footswitch can be used as a tap switch to enter the tempo, while the Tap Divide button provides various rhythmic divisions of the set tempo. For further sound processing, a filter knob is available in addition to the controls for delay, Feedback and Blend . Knob settings below 12 o'clock allow the filter to act as a lowpass, while all settings above 12 o'clock create a highpass filter for attenuating low frequencies.
