Deep & Vibrant Mojo from the 70s

Guitar music in the late 70s was hugely impacted by the now recognizable and revered organic warmth of the Boss classic CE-1 Chorus/Vibrato pedal. Released in 1976, the CE-1 skyrocketed Boss to the top of the guitar chain by introducing a revolutionary design that was adopted by Andy Summers (The Police), Jeff “Skunk” Baxter (The Doobie Brothers), and John Frusciante (Red Hot Chili Peppers).

The CE-1 Chorus Ensemble adopted the very popular at the time Roland JC-120 Chorus Amplifier circuit and captivated its listeners with thick organic modulation and gooey pitch-shifting vibrato, which you can now have access to at the tip of your fingers, using our Synergy Core platform.

We carefully measured and emulated the unique non-linear response of every single component found in the pedal and recreated it in a digital form using the original schematics. In our BBD-Chorus effect we included the same stereo modes as the ones found on the hardware unit – Split (Dual) and Basic (Classic), but we also carefully developed 2 additional modes unique to our design (Wide & Cross).

The extended features on our CE-1 emulation combined with the muscle power of the most powerful onboard processing system on the market today (Synergy Core) vastly expands the capabilities and uses of this pedal, propelling it beyond guitar-only processing and into the realm of sound design and music production.

Tip: Place the plugin on a parallel chain and subtly feed your whole mix into it or just some selected instruments. Now the Stereo Mode to Cross (subtle blend between Basic & Split) whilst keeping the Level Control at its mid position and turn all the other knobs on maximum. Switching between Chorus and Vibrato will give you two unique and distinct Mix Bus effects that will glue your track, unlike any other processor. At this setting Chorus will give you mellow, lush, and warm glue, whilst Vibrato will add extra depth and vibrant color to your track.
