Echo-1 Standalone Analog BBD Delay

Retrogradus Instruments Echo-1

Bring the organic warmth of analog delay to your studio with the Echo-1 from Retrogradus Instruments, a standalone all-analog BBD stereo echo unit with Eurorack compatibility. The delay lines contained within are true stereo, meaning there are two individual delays running in parallel that can be affected individually. Clock each one in sync or separately with the discrete left and right channel clock CV inputs, or set them both in Free-Running mode for more unique rhythmic movement. Modulate the texture of your delay with the internal LFO, which can affect both the Tremolo and Vibrato effects. These parameters each have their own depth slider, along with the ability to invert the shape of each one for modulation that plays in tandem with each other or separately. Sync these effects to an external clock, or control the LFO with a different clock signal using the corresponding CV input. If your set-up is in need of the unmistakable feel of an all-analog stereo BBD, the Echo-1 from Retrogradus Instruments provides superb sound and deep control for any echo sound from the recognizable, to the abstract.
