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



Recognizing the people behind a musical instrument's creation is as vital as recognizing the artist who plays it.  In that spirit, The Midium® asked Collision Devices to please sign the Collision Devices BLACK HOLE SYMMETRY pedals in our collection.  They decided to sign as a team, which is very fitting for a tightly knit group of friends developing unique pedals, together, in their shop in France.  Our exclusive Signature Edition units form an extremely rare segment of this series.  Please note that since each pedal was individually signed, signature placement may of course vary from the example in the photo you'll find in the gallery.  It is The Midium®'s hope that you feel a deeper connection with your Collision Devices BLACK HOLE SYMMETRY Signature Edition pedal, with the knowledge that the makers have added a personal touch to the units in our collection.  We hope you enjoy this special pedal, as the proudly French group of friends at Collision Devices put so much of themselves into their designs.




Let’s dive into a black hole!
