Little Copper Chorus is designed more to give the playing feel of a Fender Vibratone than a typical chorous and as such shows a modern use of an effect that otherwise has been overused for decades.

Back in the 1980's you just had to have a chorous or be sacked from the band.
Secretly in the mid 80's I listened to SRV and Lonnie Mack on my way to rehearsal and likewise secretly practiced using chorous ahead of distortion to get the sounds more of an organ.
Typical chorouses run triangular wave oscillators while the LCC runs a sinewave oscillator and sinewave is also what is producedc by an electrical motor such as one in a Vibratone cabinett.
That said LCC can produce standard chorous sounds.

LCC sports three controls

Width that sets the width or depth of the modulation

Colour that is tone control that allows a mild midboost- chorous as an effect has a slight tendency of becoming scooped and so to allow settings that protrudes Colour knob has been added.

Speed that allows control of speed from almost standing still to rotary and at full speed there's a sound of a rotary speaker rather than a detuned sound
