GMT Games
GMT Games is a California-based wargaming publisher founded in 1990. The current management and creative team includes Tony Curtis, Rodger MacGowan, Mark Simonitch, and Andy Lewis. The company has become well known for graphically attractive games that range from "monster games", of many maps and counters, to quite simple games suitable for introducing new players to wargaming. They also produce card games and family games. "The Washington Post" called GMT "the modern hobby's highest-profile wargame publisher".
Gallien-Krueger
Robert Gallien started his company, then named GMT, from his garage in San Jose, California, while working as an engineer for Hewlett-Packard. His first amps were the GMT 226A and 226B (named after their power output) and were unconventional in their design because they were built around transistors instead of tubes. Carlos Santana was one of the first to buy a GMT 226A (serial #6) and it can be clearly seen in the Woodstock movie.
