JOYO Technology are co-founders of Dr J guitar effect pedals. Dee Leung, head of the Dr.J engineering team in Shenzhen, began his career as a musician. He liked fiddling with various pedals when he was a student in college, analyzing tones and circuits from low-end pedals to advanced handmade ones. Dee Leung continued focusing on his pedal designs in his evenings, at home as his passion for electronics grew into an obsession. Although he had bought some pedals, he couldn’t afford to collect so many of the costlier effects, so he made an effort to network with local guitarists and other effects-using musicians with sizeable pedal collections of their own.
