In the words of Mythos Pedals:

The Oracle Analog Echo is finally here. This pedal pays homage to the Japanese echo pedals that I adore but isnt a direct clone of anything. Designed by John Snyder of Electronic Audio Experiments the Oracle is built around two reissue MN3205 chips. The layout is very straightforward and simple, the knobs are Time, Feedback, and Mix with a Tap Tempo and True Bypass On/Off Footswitches. The Time knobs allows you to get up to 600ms of delay time, but using the Tap Tempo you can push that time even further. Tapping a longer delay will begin to degrade the signal and repeats.
