The original Green Shift specialized in electronic repairs and offered second-hand musical instruments on an occasional basis only. The owner retired in the early 1980s and sold his business to then-employee Donald Taylor, who began stocking a greater selection of musical instruments as well as a small assortment of comic books. He ultimately opened a larger showroom (the current location) on Nebraska Avenue, dedicating a generous portion of its maze-like interior to new, used and vintage musical instruments, amps, accessories, and an array of note-related gadgets and books. Meanwhile, the demand for comics grew so significantly that the collection soon overtook the stores other half. Nowadays, Green Shift stocks over 200,000 new and back-issue comics, Manga comics, graphic novels and non-sports cards, as well as memorabilia of all sorts, action figures (from Homer Simpson to Jerry Garcia), fiction and nonfiction books, DVD and VHS movies, imported toys, T-shirts and other random must-haves. 5226 N.
