This three mode reverb lets you hear what some of the most classic effects sound like on just the reverb. Allowing you to create new sounds and textures like never before.

Fibonacci
All of the Delay Space in the reverb engine for this pedal are in the Fibonacci series. What does this mean for you? You'll probably make more money, look better (see golden ratio below) and find true happiness. For Keeley it means a secret pleasure in defining a reverb that is unique and possibly more musical. Since great works of art like Debussy's La Mer have been crafted by using the Golden Ratio, why not create lengths of time defined by such ratios? 0, 1, 1, 2, 3, 5, 8, 13, 21, 34

Harmonic Reverb
This mode is like a vintage Brownface Amp or the DynaTrem, Harmonic Tremolo on the reverb. Imagine choppy waves of tremolo on your verb! All with the a delicious hint of Vibe! 

Vibrato Reverb
Pitch Bending Reverberation Machine. From mild chorus to spacey bayou tones, this is one for modern psychedelics. For this one you have to imagine maybe both the source and the reflective wall moving! Maybe even accelerating with respect to each other. 

Phaser Modulated Reverb.  
Maybe the most mild but in a way that lets you appreciate some of the space around notes. This notch filter in your reverb space gives the illusion of the reflecting wall morphing from carpet to wood, then to steel and then glass. Round and round. Get the idea? Dynamic reflections in an all new space.
