The HEX delay is an unconventional and versatile effect.

 

The delay time ranges from a very fast, almost chorusing effect, to an abysmally slow; go make a sandwich delay.

The slower the delay, the noisier it gets, until it just breaks down into bleeps and squeals. The feedback knob can transform the effect into a fuzzed out distortion, or when combined with the decay knob extreme oscillations can be manipulated
