Moody Sounds Mushroom Echo is a combined echo / pitch pedal which is controlled optically. It can produce everything from freaky and bent out of shape notes to soft chorus like sounds. Very expressive for the creative musician!
The pitch and echo is controlled by covering/ exposing a sensor, which is placed in the right corner of the pedal. The white knob is a sensitivity control for the sensor and the red knob sets the number of repeats.
Moody mushroom has also a mode-switch. Switch it and the pedal behaves like a regular echo. Its two knobs now set interval time between the repeats (white) and length of repeats (red).
The Mushroom has true bypass and is powered with 9 or 12 volt dc adapter with common polarity (not included).
