Electro Harmonix Nano Clone

"The Nano Clone presents a lush, true analog chorus at a very affordable price.
 
This compact battery operated Chorus pedal features depth and rate controls, with an LED function indicator.

To produce the Chorus effect, the Nano Clone bends the frequency slightly from the input source and mixes this altered signal with some direct unaffected signal. The combination produces a doubling effect.

The depth switch controls the amount of frequency change that occurs in the altered signal. The rate knob controls the rate of alteration between raising and lowering the frequency. The red LED indicates when the effect is switched on. The footswitch engages and disengages the Chorus effect.

* Please note this pedal has to be powered by it's own power supply (9v battery or plug) and won't work with daisy chain power supplies."
