The TC Electronic Fluorescence Shimmer Reverb is a compact reverb pedal dedicated to shimmer sounds, the octave-up, bell-like reverb effect associated with ambient and cinematic guitar playing. TC Electronic describes it as a shimmer reverb pedal with an intuitive four-knob interface for modern and ethereal reverb sounds1. It is a digital design: the press release announcing the pedal speaks of "state of the art digital algorithms and high quality materials" aimed at the gigging musician2.
What it does
Shimmer reverb takes the reverb tail and feeds a pitch-shifted copy of it back into the reverb, building a swelling, orchestral wash behind the notes. TC Electronic's own pitch for the pedal is grandiose: the announcement says it "puts the colossal, interstellar tones of Eno & Lanois at your disposal for an instantly grandiose orchestral guitar sound"2, a reference to Brian Eno and Daniel Lanois, the producers whose studio work helped define the shimmer sound.
The four-knob layout keeps that simple to reach:
| Control | What it does |
|---|---|
| Reverb | Sets the reverb itself3 |
| Mix | Blends wet and dry signal3 |
| Tone | Shapes the reverb's tone3 |
| Shimmer | Sets the shimmer layer3 |
How it compares
MusicRadar's reviewer placed the Fluorescence at the cheaper end of the pedal market and summed it up as "a straightforward Shimmer Reverb pedal at a good price, without the extras of the" Electro-Harmonix Pico Shimmer, the pedal the review was comparing it against3. The trade the reviewer describes is plain: fewer features than some rivals, at a lower price, with the four knobs covering the essentials of the effect.
"At the cheaper end of pedals, this is a straightforward Shimmer Reverb pedal at a good price, without the extras of the Pico Shimmer."
If you want more reverb options from the same maker, TC Electronic's wider reverb range runs from the Hall of Fame 2 to the T2 Reverb and the Skysurfer; the Fluorescence sits in that line as the shimmer specialist. See the full range on the Reverb Pedals page.
Availability
The pedal was announced in January 2018 with pre-orders open at Musician's Friend and store availability at Guitar Center in the US expected late in the first quarter of 20182.
