Isaac Jang studied with Bryan Galloup at the Galloup School of Guitar Building and Professional Guitar Repair in Big Rapids, Michigan, before getting a job at Westwood Music in L.A. He then started working with Kathy Wingert - an apprenticeship that lasted ten years. He now has his own workshop in Hollywood, California where he makes ergonomic acoustic guitars by hand. Some of his guitars have a clever cutaway - he refers to it as a bendaway- using an idea borrowed from Mitsuhiro Uchida.
