New module!

We're delighted to announce a new Eurorack module, Cicely.

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.

Cicely is available immediately, stock permitting - see Where To Buy.

"Instruments that sound good inspire better music, and it's a struggle to make music with bad-sounding instruments, irrespective of how talented you might be. Software instruments are no different: although they are usually discussed and sold in terms of their 'features'  what really makes you return to an instrument repeatedly is the much more elusive factor of inspirational sound quality.

"I don't know enough about programming to understand why some software tools fascinate you while others make you want to get another job, but I do know that when I use anything by ES I get excited by what I'm hearing. These tools have the sonic richness of great analogue instruments - with the features of innovative digital ones."
