In the words of EarthQuaker Devices:

Thats right, weve taken a digital delay, an analog delay, and a tape delay and merged them all together as one pedal with six presets, a tap-tempo, and user assignable expression control. Take a moment to compose yourself, we totally understand. With just four knobs, one three-way switch, oneSave/Recallbutton, and two footswitches, he made the impossible possible and now your guitar playing shall reap the rewards!Each of the three modes offers up to one second of delay time. From noon and back is 500 milliseconds to zero, which has its own character. From 500 milliseconds to one second of delay time, its an entirely different beast. Dial them in for shorter delay times where they really excel and add loads of atmosphere and vibes. Push them further for rhythmic delays that are perfect for strumming and adding extra ambiance for your riffs. And the tap tempo is truly precise and responsive so you can lock in your rate quickly within the first revolutions.

Features:

• Three-mode delay with the ability to save and recall six presets, tap-tempo, and user-assignable expression control
• Mix, Time, and Repeats knobs dial in the sound in each of the 3 modes
• Mode D:Digital Delay mode offers nearly infinite repeats that hold their fidelity while gradually rolling off the top end with each regeneration.
• Mode A:Analog Delay mode is more mid-focused in the initial attack and gradually degrades while getting darker with each repeat.
• Mode T: This mode resembles an old, well-loved tape delay with all its glorious artifacts. Dark and moody with just a hint of distortion when you hit it just right.
• User-assignable expression control
• Dedicated tap tempo footswitch
