The Lithium Analog Chorus is a modified version of the Electro-Harmonix Small Clone chorus pedal, which was originally released in 1979. The Small Clone was a popular choice among musicians, including Kurt Cobain, Jonny Greenwood, and The Edge. It was known for its warm analog chorus sound.

The original Small Clone circuit had two variants, one using the rare SAD1024 chip and the other using the more common MN3007 chip. While it is often believed that Kurt Cobain used the SAD1024 version, there is no definitive proof of this. The MN3007 variant is actually more common and was used throughout the entire production run.

In the early 2000s, the Small Clone was reissued with some small circuit changes that altered its sound slightly. The reissues can be modified to match the vintage specifications if desired.

The Lithium Analog Chorus is an expanded adaptation of the MN3007 Small Clone. It adds a Depth control, which was converted from a switch, and a Mix control. These additions allow for more versatility and control over the chorus effect. The build notes for the Lithium provide extensive details for those interested in the changes made to the original circuit.
