Project overview

Dome Device is a unique 2-in-1 fuzz board that combines the classic sound of two legendary pedals into one compact unit. Inspired by the now-discontinued EQD Spires it offers a one-of-a-kind playing experience that is sure to take your sound to new heights. Get ready to double down on the fuzz factor!

Introduction

Dome Device combines the sound of two legendary fuzz pedals – the Rosac Nu-Fuzz and EQD’s Dream Catcher (a modified Fuzz Face). Both pedals are known for their warm and harmonic distortion tones, producing a smooth, velvety sound perfect for blues, rock, and heavy metal.

But the Dome Device isn’t just a replica but a modern take. The Nu-Fuzz section comes with more easy-to-find values, while the Dream Catcher section ventures furthest from the original source while maintaining its roots. This means lots of experimentation and fun as you explore the different sounds this pedal can produce.

With two footswitches, you have the ultimate flexibility in tone shaping. Turn on the unit and switch between the two fuzz circuits with ease. So what are you waiting for? Get ready to rock!
