An affordable classic!
The Small Clone is easily one of the most famous Chorus pedals ever made. A favourite of Kurt Cobain's, this Small Clone is featured on most of Nevermind's clean parts and a good few of the lead parts, too! It's a thick, warm chorus sound with lots of character and personality.
One switch and one knob are all you need to coax a multitude of high quality chorus sounds from the Small Clone. The rate knob will take you from placid to watery swimming ripples whilst the depth switch alters the frequency slightly more to produce a more obvious effect.
Whether Grunge was a big thing for you or not, the sounds available form the Small Clone are extremely satisfying and eminently usable.
