From the vendor

Project overview

The Cosmos Delay is a triple-head PT2399 delay, inspired by Roland Space Echo, Designed by Chris Carter. Only available as DYI.

Introduction

The Cosmos delay takes the original concept of the Roland Space Echo of 3 individual tape heads and takes it to the extreme. This circuit adds an individual delay time and volume control to each head so you can create your own rhythmic textures. If that is not enough, you even have a rotary switch in charge of synchronizing the delay heads in four different ways to create your galloping echo wave structures.

The Vpath rotary switch is another exclusive tool of this incredible circuit. This knob allows you to set where you are placing the feedback loop, which you can combine with reverbs and other modulations to enlarge your spaceship. This circuit also comes with a dry switch, tails control, and a slam switch to momentary drive your signal into fully chaotic feedback.

This is not a beginner-friendly project, and we recommend that you take your time and patience to get the best possible results.

This board has been corrected and improved a couple of times, being 2v the final revision. All the previous versions are fully working. You can also check the Cosmos Delay SMD version that comes with most resistors and capacitors already soldered on board as SMD components.
