Shimmer reverb is one of those effects that you have to hear for yourself before you really know what it is.

Originally pioneered by recording legends Daniel Lanois and Brian Eno, shimmer is produced by layering a tail of reverb that is pitched up an octave and sent through a feedback loop on top of the dry signal.

This produces lush soundscapes that take on a life of their known, ranging from voluptuous chimes, to interstellar travel-like sounds that will evoke memories of Carl Sagan's Cosmos while you're playing.

A string section in your gig bag

Used extensively by U2's The Edge, the shimmer effect has been adopted by scores of shoegaze guitar players for conjuring up huge, vibrant soundscapes, bursting with sparkling clarity.

Ever since U2 started working with producers Eno and Lanois, shimmer has found its way on to classic performances like With Or Without You, 4th Of July and City Of Blinding Lights.

Wherever there's a need for grandiose string sections of ethereal presence to add body and scope to a passage, Fluorescence fits the bill. 

Complexity made clear

Fluorescence's four controls allow you to intuitively fine-tune your ethereal reverb tone in depth.

A Reverb knob adjusts the amount of tail on your dry signal for short or long ambient resonances.

Adjust the balance between the reverb tail and your guitar sound with the Mix knob, while the Tone knob sets the amount of sparkle you want from your reverb.

Finally, the Shimmer knob turns up the intensity of crystalline, angelic octaves that fill up the air with thick ambient tones

Truly roadworthy

Fluorescence Reverb is built to withstand the rigors of the road with a sturdy metal frame and high quality components.

True bypass circuitry keeps the integrity of your signal pure of any tonal coloration, while top mounted input/output jacks make it easy to fit the pedal on any pedal board.
