Cicely is an “octave fuzz” effect, inspired by the legendary “Octavia” guitar pedal, created by Roger Mayer and most notably used by Jimi Hendrix. There is an interesting history of the pedal on Roger's website here. Cicely adapts the concept for the modular environment, adds some extra features, and of course puts the effect under CV control.

The effect is essentially one of adding an octave on top of the input note, but this only really applies to pure input tones – for more complex tones, the sound is changed in all sorts of interesting ways. This is combined with the possibility of overdriving the sound for even more edge, while the unique 'Centre' control adds asymmetrical clipping.

As a bonus feature, Cicely also includes an envelope follower.

The module is 100% analogue.
