$ The Mooer Audio Ana Echo is a very small Analog echo pedal that sounds great! Don’t let the small size fool you, the tones in this box are big! The Ana Echo has 3 knobs... Rate, intense and echo. Use the Mooer for rhythmic delays or set the echo back a little for some added depth to your lead tone. The Mooer Ana Echo can also be used to self oscillate for outer space tones!
