I have been using delay and reverberation since the middle 1960s. I use them to make what is almost inaudible to the ear, audible. I do not use them to play loudly but to make the higher harmonics heard. ↗
My experience in Amsterdam is that cyclists ride where the hell they like and aim in a state of rage at all pedestrians while ringing their bell loudly, the concept of avoiding people being foreign to them. ↗
