$299 USD

The initial preorder batch of the all-new Chorus has been released! Please note that your pedal will take approximately 4-6 weeks to ship from the date of order placement. 

The same, lush tones you know and love, now with new, modern features and upgraded components. It's more than just a facelift - it's the start of a new era. 

Our best-selling pedal provides the distinctive lush chorus, and true pitch-shift vibrato of the late 70's “CE-1” using the same analog BBD as the original unit. The Chorus Ensemble’s unique tone is the standard by which all other chorus effects are measured.


The Retro-Sonic Chorus is capable of a wide range of sounds, from analog chorusing to pulsating vibrato. The unique Vibrato feature that was incorporated on the original can simulate a Leslie rotating speaker. The chorus and vibrato functions are selectable through a footswitch control, allowing desired presets to be maintained separately.

Issues from the previous model, such as power cutting in and out, hum, and broken chips have all been resolved. [Discuss here the technical shortcomings of the first pedal and how they've been mitigated]
