Based in Montreal, Canada, JTEX designs and builds electronic gadgets for musicians and audio professionals. It was started by Jerry Catanescu at the height of the Covid pandemic, to help him stay sane during the long lockdowns.

Jerry has been building guitar effects, amps, EQs and other electronics projects since he was in middle school, back in the 80s. His electronics hobby turned into a career that took him from recording studios to telecoms to electronics manufacturers, and eventually back to the world of pro audio. He is Chief Electronics Technician at the Sound Recording Area of McGill University.
