ENDANGERED AUDIO RESEARCH AD4096 ANALOG DELAY. The Endangered Audio AD4096 is much more than just another analog delay pedal. This unique soundscaping device allows the user to craft their own vistas of pure harmonic bliss. The Endangered Audio AD4096 is all analog with delay repeats that gradually decay to lo-fi goodness with startling clarity. With anywhere from 40-400ms delay time, the AD4096 can provide both quick slap-back and longer, ethereal repeats. The Infinity mode is a unique function that basically loops the repeats infinitely as they gradually fade into the dominant tone of the notes played. This provides a shifting “cloud” of background wash that drift back and forth behind the notes. Using the Aux output, the Infinity mode background tone can be played over by the guitarist. The Aux output also allows for spillover effects and splitting the input signal.
