Collision Devices' description of the Collision Devices Black Hole Symmetry delay / reverb / fuzz mono pedal


Reach infinity.  

Let’s dive into a black hole!

Create warm waves & trembling repetitions, space reverb sounds and of course make a lot of noise by recreating the fury of a black hole.

The Black Hole Symmetry is a Modulated Delay / Pitch shifted Reverb / Destruction Fuzz pedal.



Travel through the Ergosphere, the Event Horizon and the Singularity. The 3 parts of the pedal which can be played together or separetely.

Each pedal is designed, assembled & tested by hand in our workshop in France.

The B.H.S. has a lifetime warranty.


Three effects.  One pedal.


Destruction Fuzz

The single setting "Disintegrate" allows you to raise your sound.

Forget the fact that your drummer plays loudly. 

Settings :

Desintegrate : Volume setting with a huge fuzz.

Protect your ears please. 



Event Horizon.

Pitch shifted Reverb

Long reverb based on the FV1 chip.

Harmonizes the reverb signal with a pitch shifter. 

Settings :

Mix : Proportion of wet signal in the mix

Echo : Echo time (max 15s)

Radiancy : Proportion of pitch shifter in the echo signal

Pitch : Shifts the pitch of the note




Modulated Delay

Based on the PT2399 chip to have a warm echo.

The echo signal is modulated by two oscillators. 

Settings :

Mix : Proportion of wet signal in the mix

Time : Time between each repetition (From 0s to 1s)

Feedback : Number of repetitions

Modulation : Proportion of modulation in the delay signal

Speed : Speed of the main oscillator

Trimmer : Speed of the triangle oscillator
