I Dream of and Live for Great Guitar Tone

My name is Steen and I live in Copenhagen, Denmark. I am a passionate guitarist, a driven engineer and something of a dreamer who constantly pursues divine guitar tone.

Decades of gigging and studio sessions taught me that nothing takes my focus off the music like poor sound which made me obsessed with the idea of creating the perfect overdrive pedal. A pedal that sounds and feels like a real tube amp being cranked. A pedal that allows me to keep my sole focus on playing the music that I love. A pedal that inspires me to play my absolute best!
