Decay: Decay controls the amount of time it takes for the reverberated sound to disappear. Ours provides a range from a realistic, close-quarters reverberated dimension to a walk-away-and-come-back signal of complex, still-ringing musical reflections.

Slapback: Slapback is what we call predelay. Predelay creates distance. How soon or late you hear the first reflection is crucial to crafting the reverberated space. Sometimes you do not want any delay between your note and the reverb. And sometimes, for clarity’s sake, you want the reverb to wait a moment before joining the dry signal. Such a setting would enable short, staccato, single-syllable type expressions to finish articulating before being suffused AND being joined by the tail-end of previously reverberated sounds. But when the illusion of infinite space is required, set your Slapback to zero and you’ll streak vividly away like Dr. David Bowman breaking free of Jupiter’s gravitational pull. The Keeley Aurora Slapback setting provides you with a sufficient range of time, from zero milliseconds to 100 milliseconds, ample time considering a pedal-board footprint this small.

Warmth: Dial up the warmth. Opposite to most tone controls, ours increases the warmth, as it is a dampening control. Its brightest setting is when completely dialed down.

Blend: Blend will take your 100% analog dry signal and blend in the reverb, from just the slightest mix of wet to much more. Because the Keeley Aurora Reverb is a pedal-board unit, we suggest you place it at the end of your pedal chain and use the Blend Knob to tailor your sound.

The Toggle Switch: The three most popular reverb styles that don’t come built into your amplifier are Room, Plate, and Hall. In the smallest footprint possible, we offer what used to take up entire city blocks or an entire studio room. You can achieve cathedral resonance, enormous surface areas of sheet-metal plate sounds, or convincing room decays. Room sizes range from something like a broom closet to that of a barn. (And I also want to add that careful adjustments to the Room settings yield a signal bordering on the verge of spring reverb, so if your amp doesn’t already have a tank, we’ve got you covered.)
