Dreadbox has re-released the Hypnosis Time Effects Processor, but this time, it’s in a kit and Eurorack compatible.
However, it’s also very different from the original desktop unit and has far fewer features. You get Chorus/Flanger, a delay and a real spring reverb wrapped up in a lovely box with modulation patch points and a mono output. I go through the whole build (which is easy – no soldering) and then attempt to get to grips with the effects. You’ll find lots of thoughts and nice long demonstrations.
