ELECTRO-HARMONIX / SMALL CLONE Chorus This is a famous analog chorus pedal known for being used by Kurt Cobain of Nirvana. Its clear, rich, three-dimensional, and warm sound is a unique tone that cannot be obtained with other chorus pedals. With simple controls, you can achieve a doubling effect and simulate the tones of a 12-string guitar or a Leslie speaker. The two-stage DEPTH switch allows you to switch between a gentle effect and a more intense, vibrato-like effect. - The battery compartment on the back has been removed, assuming use with an AC adapter and on an effects board. The battery cover is included, but please note that functionality has only been confirmed with an AC adapter. - Will be shipped in the original box. - Velcro is attached to the bottom as it was used on an effects board. You can use it as is when setting it up on a board. Please remove it if you don't need it.
