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. Most people saw him as a reticent modding freak, a pedal head, or pedal geek considered a relatively introverted kind of guy.
When Leung submitted one of his own pedals for a graduate design project, his teachers didn’t even know what it was. 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. All those people were happy to lend their collections to his research.
Dee took this pedal to those musicians who had lent him pedals over the years and let them try it out and to thank all his friends for their years of support, Leung gave his new pedal to each one as a gift. The overdrive pedal gained increasing popularity, and more and more local blues guitar players asked Leung for a custom-made unit, which was the predecessor of the Green Crystal. Terry Li from JOYO, one of the founders of Dr.J, was among the earliest users of the Green Crystal.
Terry told his friend Dee Leung that he ought to let more people try this ingenius pedal. Meanwhile, Terry was preparing a start-up to market select pedals with the aim of bringing musicians a new kind of inspiration. This idea caught the attention of JOYO Technology which later assisted with investment for the DR.J effect pedals brand start-up. That moment was the turning point that allowed the independent development of this new brand--what is now Dr.J--to become possible.
Terry Li named his pedal company after the first initial of his favorite guitar player, Jimi Hendrix, implying that every Dr.J pedal embodies Jimi’s unconstrained creativity.
Dr.J is serious about creating inspiring tones for passionate musicians, and to ensure superb tone and outstanding quality, every Dr.J pedal must pass a series of strict tests in the hands of a professional.
From tonal selection, to circuit design and unique layout, to the selection of every single component down to the finest detail, we are committed to the pursuit of perfect pedals regardless of cost.
Dr.J is a young guitar effects company, using unique concepts to create extraordinary unique effects pedals co founded by JOYO Audio Technology.
