About JTEX

JTEX is a microbusiness based in Montreal, Canada. We design and build electronic gadgets for musicians and audio professionals. Our specialty is small volume and one-off custom projects.

JTEX was founded by Jerry Catanescu as a pandemic pastime that will hopefully outlast the crisis. Jerry has been building guitar effects, amps, EQs and other electronics projects since middle school, back in the rocking 80s. His electronics hobby turned into a full time career that took him from telecoms to recording studios to electronics manufacturers and eventually to higher education. He is the longtime Chief Electronics Technician for McGill University's Sound Recording Graduate Program.
