The Electro-Harmonix Nano Clone Chorus Effect Pedal is everything you love about the Small Clone in an even more compact die-cast package. This compact, battery-operated Chorus pedal features a simple and effective Rate knob, with an LED function indicator. To produce the Chorus effect, the Nano Clone slightly bends the frequency of the input source and mixes this modified signal with an unaffected direct signal. The combination produces a doubling effect. The depth switch controls the amount of frequency change that occurs in the modified signal. The rate knob controls the rate of change between increasing and decreasing the frequency. The red LED indicates when the effect is activated. The footswitch turns the Chorus effect on and off.
