Sound Trade were made by System Craft in the 90s and petered out by the early 2000s. They were incredibly well engineered with superior playability and materials.
I believe the makers started a new company or went to work for another high end Japanese brand, which is why the brand ceased in the early 2000s.
None the less, these builds are up there with the rest of the best and compare with the likes of Moon, Combat, Atelier Z, Sadowsky etc etc.
This one was on a bit of a sorry state cosmetically when I received it, so I decided to revamp it and modify the circuit so it has added passive mode with a master tone and a drop D tuner.
