Located in Montreal, Canada, JTEX develops and builds electronic devices for musicians and audio professionals. We specialize in onboard electronics for bass and guitar, but we've also been known to make pedals.

JTEX is owned and operated by Jerry Catanescu. He started building guitar effects, amplifiers, equalizers, and other electronics in his teens as a hobby. This passion led to a career that spanned several recording studios, telecom and electronics manufacturers. Jerry is the longtime Chief Electronics Technician at McGill University's Sound Recording Program.
