The classic chorus! Analog chorus pedal popularized by Kurt Cobain. The finest analog chorus sounds: from clear, rich and dimensional to warm pulsating warbles, can be intensified with the Depth Control. Simple tweaks generate exciting doubling effects. Chiming 12-string tone, or Leslie-like warbles.Quick Specs – True bypass – 9-volt Battery included The Small Clone is a compact battery operated Chorus device that features DEPTH and RATE controls, with an LED function indicator. To produce the Chorus effect, The Small 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. For optimum performance, use a 9V battery, although a 9V 100ma tip-positive AC adapter with an 1/8” plug can also be used (not included). Plug your guitar into the INPUT jack and your amp into the OUTPUT. Please note that as long as anything is plugged into the INPUT, a drain is placed on your battery. It is recommended that you disconnect the INPUT when the unit is not in use to increase battery life. The DEPTH switch controls the amount of frequency change that occurs in the altered signal. The rate of alteration between raising and lowering the frequency is controlled by the RATE knob. The red LED indicates when the effect is switched on. The footswitch engages and disengages the Chorus effect. The small jack on the back of the Small Clone is for a 9-volt battery eliminator capable of delivering 100 mA of current. The units battery may be left in or taken out when the eliminator is in use.
