From the distant echo of cathedrals to 600-pound sheet-metal plate vibrations to spring reverb coils in a tank, reverb captures our imaginations and plunges us deeply into our musical psyches. Few effects complement a guitar better than reverb.

At Keeley Electronics, the Aurora Reverb had to meet certain specific criteria: It had to be affordable with no compromise to audio quality; easy for guitarists to use and be inspiring; and offer the essentials for tailoring your tone without a dozen knobs to learn. The final product does all of that with a true-bypass, 100% dry analog path, low noise, 24-bit, high-fidelity reverb processor.

The Aurora Reverb's controls offer everything from pristine fast reflections to ethereal spaces to deep, dark, and endless caverns.

Decay: Decay controls the amount of time it takes for the reverberated sound to disappear. The Aurora Reverb's Decay 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 essentially a pre-delay. Pre-delay 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' 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' gravitational pull in 2001: A Space

Odyssey. 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: Opposite to most tone controls, this one 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, 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, the Aurora Reverb offers 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.

All in all, the Keeley Aurora Reverb promises to provide the essentials guitarists are looking for when they need reverb on their pedal boards. Like that ethereal glow to the mighty Earth herself, Aurora creates a natural halo of sound in the atmosphere of your magnificent core tone.
