If you're looking for surgical sterile repeats, then you've come to the wrong place.
The Doomsday Delay gives your tone a warm vintage character that plays just as nicely with high gain as it does with cleaner tones.
The Mix knob gives you the ability to adjust how much of your wet delayed signal is blended in with your guitars dry signal.
The Delay knob adjusts the length of the time between repeats. At longer settings you will get even more vintage tape echo style tones giving you extra character to help stand out in the mix.
The Repeat knob controls the amount of repeats from one to infinite repeats. Crank it up to the max and you will get a chaotic mess of awesomeness not unlike Hendrix himself.
Combine these simple functions with a great sounding circuit, a two year warranty and killer build quality, and you've got the Doomsday Delay.
