Quick story about the founder Kevin - being an enthusiastic jazz guitar collector and also a passionate jazz guitar student at Root's Jazz Academy in Tokyo (, he was lucky enough to play the variety of the jazz guitars, from US-made Gibson to the hidden champions of Japanese hollow bodies. Over the years he has built a substantial collection of the guitars up to the point where he realized these treasures were too shiny and valuable to just stay still in the corner of the room. So in 2011, he sat down together with a group of e-commerce platform management consultant, software developer and graphic designer to actualize the idea on an online marketplace also a mini encyclopedia of Japan vintage guitars... and the rest is history.
