1976 in Montreal Canada, Peter Janis and Denis Rozon meet. Peter was a budding young guitarist that was playing in bands and working at Steve's Music Store to pay for new gear and Denis Rozon was an office equipment technical representative with a passion for guitar sounds and electronics. Peter was dissatisfied with the options available to guitarists and wanted to find solutions. Denis loved to tinker!

The two original 'Boneheads' started collaborating on the first generation of tube distortion pedals and developing new products including the world's first 3-channel guitar amplifier. According to Peter Janis: "Our 1st distortion pedals were just plain average! They had huge top end and did not yet have the sweet tone that we were searching for. But it was a start and we knew we could only go up from there. The amps on the other hand were turning heads from day one! This was the foundation from which we built our careers".
